Thanx dude, i just fixed my vx922 thanks to you. It was pretty hard, to plug back the power supply board onto the the logic one, but it was worth it, is working now. Thanks again.
Mine is VX1940w, my light keeps blinking. And it display white and fuzzy images, then it blank until now. What is the problem come from and what is the problem? LCD or CPU?
I just wanted to thank you for posting this video. I just had the same problem with my Viewsonic monitor; mine was a slightly different model but looked the same. I found three caps that looked bad, replaced them with new ones, and the monitor works again!
@Eapix Capcitors have 2 numbers on them: capacitance in uf and a voltage rating. Replacement capacitors need to match the capacitance of the bad capacitors, and the voltage rating needs to be as high or higher than what you are replacing. Electrolytic capacitors have polarity (+ and -), and it is essential that you put the + and - leads into the proper holes. Make a drawing noting polarity before you remove the bad capacitors.
@HabsCabs888 No. You must unsolder the bad capacitors and solder in new capacitors. Search YouTube for "unsoldering capacitors" and "soldering capacitors," and you will find multiple videos.
I have a ViewSonic VX922 that had this problem. Your video put me on the right track. I replaced a 470uF and two 1000uF capacitors that were all bulging up. Fixed me right up for $5 in parts. Thank you for the video help!
My capacitor seems to be fine. But the green blinking light happens and the monitor flashes. The capacitor has these black dots on top but not domed up. Could it be something with the power cord? I have a 14-inch Monitor ProView. Any help? Im 14. This happened about a year ago when the power went out probably and the fuses went out.The capacitor is 470uF 25v.
Thanks for this, I had a VX922 that was dead and a VX924 that was giving me migraines with the shimmering diaplay....took both apart today, quick run to the electronics store, back home and a couple of hours later I have 2 perfectly functioning monitors! Welcome back dual screens and goodbye to migraines!
This worked perfectly! I was going to go buy a new one, but took a minute to look it up on the internet and boom there was your vid. Took me about an hour, this was my first capacitor replacement and now I want to fix everything. I had no problems and was stoked when it fired up on the first attempt. Thank you!
Hi there, I have the same problem but nothing change after caps replace, they was like new, no blow but I change 4 of them for brand new, and still green led blinking :( Any ideas ?
@cozykris Hard to say exactly. It's always easier when you can see something physical wrong on the board. It's a little like being a detective! What doesn't look exactly right? Are there any parts that look burnt? Or look like they have been extremely hot? There is still a good chance it's on this board.. Hope this helps!
@getonthetubedude Hi can I ask you where one can buy a tool that opens thin monitor cases? I have a monitor that does NOT have any screws. It would need to be pried off. I don't want to mar it (butter knife) in any way if I can buy a tool to do it right.
@ar3582 My Viewsonic monitor had a screw in each corner of the case with several fragile plastic catches along the sides. After removing the screws, I pried off the back as carefully as possible with a thin-bladed screwdriver, but I still broke several catches, as did the person who told me how to open such cases. It is better to break a few catches than to leave the monitor unrepaired. Use a few strips of clear packing tape to hold the case together if necessary.
Many thanks - replaced all six capacitors on my VX922 monitor and it's now working fine. It was a bit difficult to separate the plastic casing - you need to lever the casing outwards to release the catches - and there about three each side. And reconnecting in the circuit board needed some manhandling to line up the plug. So patience, care, and a bit of force is needed! Thanks again for posting the video!
Hey, I want to thank you for the video post. I have a VX922 and was having the green blinking light of death. I popped the case and all but the 400v cap were showing signs of bad bloating. I replaced just the 470 caps as they were the only ones available and my 5 yr old monitor is no longer dead. THANK YOU SO MUCH!! Not only have you given my monitor a new lease on life, but now I have purchased the gear for a home business. THANK YOU! :)
Just wanted to chime in and say thanks. I have had two ViewSonics (they are both Q20wb models) for a while. One has had this problem for a year or two and I just never investigated the problem—it sat around gathering dust. Yesterday, the other (my main monitor) just stopped working and its power light is now a very dim yellow. I have no idea what the problem is, but I'm going to try swapping out the "recently broke" power supply into the "ago broke" one to see if the green light prob goes away.
i have an old crt that has this problem of the power light flashing, Do you think it would be a similar fix? Should i open it up and look for domed capacitors? near where the power comes in?
@fleetwoodsucks Could possibly be the culprit here as well. Look for any signs of heat or phisical damage. For everyone, I know most of you know this , but just to be sure, always kill the juice on the equipment before working!
hi there!!! i need your help..i had a monitor problem but it is a viewsonic VE710s. i cant see where the screws are..i want to open the back of the monitor to see if theres a capacitor bulging cause my screen display is so very dark and hard to see.i change every settings for the picture but still not working..hope you could help me..thanks!!!godbless u!
I just fixed a VX922 monitor. I'm about to do the same for the 2nd. I bought them a couple of months apart and like clockwork they both quit working a couple of months apart. They've been sitting in the corner for over a year and I decided to look into their problems. The first one, that I am using as I type this btw, had all 6 capacitors blown. Just wanted to say thanks, this worked great for me so far!
hi there.great video...I have a strange problem. I have a viewsonic va1916w.When I turn it on it does work normally for 3 maybe 5 minutes and after the screen goes off but the indicating light stays on. I turn off and then on again the monitor with the power on button and then it turns on again and after that it does the same thing. I replaced a damaged capacitor but it didn;t solve the problem. Could you give me any idea of how to solve this. Thank you in advance.
Fixed my $200 monitor FOR $1.93!!!!!!! Omg. :D After disassembling my Sceptre monitor I found just 1 bulging capacitor! Went to radioshack and got matching capacitor, little solder and POW! working like a charm. Been w/o this thing for 3 months, <3 I missed it <3 Thanks a million getonthetubedude!
I repaired yesterday my VX924 with this exact same problem. My power supply have only 4 big capacitors. Three of them looked suspicious and i replaced them. It cost me € 1,35 for the parts from a local store.
Thank you for this video witch i accidentally found but now i am happy and i hope i doubled the lifetime of this nice monitor. (y)
Thank you!!! I'm the "software" kind of guy, not really the "hardware" kind, much less if it means messing with capacitors (in fact, before this video, the only time I heard about a capacitor was in "Back To The Future"). Anyway, since I thought I had to buy a new monitor I figured "what the hell, I'll give it a try". To my surprise not only was I able to do everything instructed, but it actually WORKED!! All for only $2.78 + tax!! Well, + another $7.99 for the soldering kit I get to keep ;-)
@BatistaReel Glad to see you were not afraid to touch the Flux Capacitor. "10,000 Gigawatts, Ben what wa i thinking?" I am glad to see you left your comfort zone to save some bucks. This stuff can get addictive!
after thinking it was an OS problem not being able to wake up just this monitor in my newly installed multi monitor setup, i searched and found this. I took my VX922 apart and sure enough, like everyone else, i have the same problem in the video. Thanks. I'm going to replace the caps in mine too. I have great fix-it skills but with only rudimentary electrical knowledge. I'm going to ask friends to see which values I can change and still be compatible to possibly make this more robust.
Thanks for this video!! I was probably going to throw my old VX922 out, but after watching this video, I disassembled mine and found 3 bad caps. Tomorrow, I'm going to buy an iron, some solder and find some place local to replace those bad capacitors. Full of confidence now!
Great video!!! I've been searching for possible solutions to my power button light blinking and then not comnig out of sleep mode. I confirmed the capacitor sizes and mine were 25V in both 470uF and 1000uF. I replaced all of them except the small 10V capacitor and it is working great so far and passed the simulation test to verify it's working. I went to Fry's Electronics and picked up everything I needed for only $20 to complete the repair. Thanks to this vidoe I saved my $240 monitor!!!!!
I have the same symptoms but when i took it apart and examined the caps they all look fine. No bulging/leaking on top or under. Is there any way to test them with a multimeter or something?

Please help me out here. My moms monitor was doing the blinking light thing. And I did just as you said in video. Now it comes on fine. But the picture is real white and fuzzy.

Dude, you are the best!, thanks for this stuff, that video and your work saved my VX922... thank you again for share your fix and your dedication for help the informatic comunity!!!
Hello there. Thanks for that video. It helped me fix a ViewSonic VX724 which was almost the same as the one on your video. There was no image and a friend of mine was to throw it to garbage. Cost me around 5 dollars of capacitors and tada... and about an hour work. The only thing is that once in a while, it blinks. There is like a camera flash in the center of the screen, but it keeps on working well. What would you think is the problem? Thanks for answering.
Confirmed that this works for VX922. Replaced all 5 capacitors in the row shown in the video (all next to each other on one corner), and the one in the center of the board. The smallest cap on the board wasn't bulging up, so I did not replace it. I used:
(4) 470uF 35V 105 degree caps
(2) 1000uF 35V 105 degree caps
The 1000uF caps I used were slightly larger in diameter. They were rated to take higher voltage than stock 10V caps. Thanks for this video, the fix saved my favorite monitor!
Great vid! I have my power supply board in front of me right now, and there's three capacitors that are obviously bad on my ViewSonic VX922: 470 micro-Farad 25V, 1000 micro-Farad 10V, and another 1000 micro-Farad 10V. There's a smaller one labeled 470 micro-Farad 10V that looks "domed" as well, so I'm going to replace all four. If I don't post again, it's because it worked. Thanks in advance!
@lite1979 Just as a follow-up: I borrowed a soldering iron from a friend, bought some solder and some copper braided wick just in case (to soak up extra solder). I was able to remove all of the bad capacitors by heating them up - got a little messy and got kind of close to some other solder points, but didn't melt them. I'm posting this from the fixed monitor right now. I used a nail clipper to clip the long ends off the new capacitors. Ebay is a good place to find the capacitors. $13 total
Wow and here I was thinking it was my video card. I have the same monitor, I'll have to try this. It's starting to get real bad now about not showing anything on startup.
Hey man I have the same problem. Im getting a soldering gun soon and im gunna repair this baby by myself (since warranty is void).
Can you tell me, what type of power capacitor do I need? Is their a certain brand/model? Should I order it from viewsonic or a manufacturers website? Or can I salvage one off another monitor?
Worked like a charm... the backing was a little tough to get off, really felt like I was going to break it... and some clips did, but it's all good. That was really the most difficult part!
Hey .. i am not very good with computer hardware and i have a Viewsonic VA712 17" LCD Monitor. The problem i am facing is that when i power up the montior it gives the orange light but there is a immediate flash after which even if i power on the CPU there is no display it just stays at the orange light. It would be of great help if you could tell me whats causing this. Thank you and BTW great Video ....
Yes this same problem exists in flat TV's, also in computers, theres even a class action lawsuit against either dell or gateway due to mass early PC failures--
I know of a 50" Plasma that needed four caps replaced and it did the trick, works like new.
My friend, you are the man! This appears as though it will be the solution. I have 2 monitors doing this (Mag and Gateway.) I will document the attempt and post the results here. I'll be back.
Also, I wonder if this is the problem alot of people are having with their flat TV's? I know I threw one out already. I had one cycling on and off driving me crazy. It's gone but I'd be curious for next time and friends. Got info on the same issue for flat TV's?
I repaired my VX922 (mfg 2006) thanks to this video and some of the other peoples comments. Old Caps 1x 470uF 10v 105c 2 x 1000 uF 10v 105c 3 x 470uF 25v 105c New Caps Old Caps 1x 470uF 16v 105c 2 x 1000 uF 16v 105c 3 x 470uF 35v 105c Since I'm not sure what caused the original caps to fail I bumped up the voltage on them. Some notes: - I was careful removing the back cover but still broke parts of the plastic holding clips. 1 on each side. - Used solder wick/braid to remove old solder.
Thank you so much for posting this vid. I've never soldered anything before, except maybe a tin box over 10 years ago in high school. I was able to successfully replace the capacitors (never knew what those were before either) on my VX922 and I am writing this review looking at the screen right now. Blessings to you!
Yet another happy story here. With the most dodgy soldering iron, I've ever used my VX922 monitor is now working. Now here's to hoping I can get my second one working again too.
Thank you very much indeed for having taken the time to make this video.
thank you for your videos. The problem is i have replaced the capacitors in the power supply of a Samsung monitor (Power Board IP-35135B). I even replaced the ones that looked fine in case they couldn't hold up charge anymore. Still no success. Back light still doesn't lightup. I know for a fact its the power supply problem because i have tried it with a different known working one and the monitor lights up.
Do you have any solution? Could it be other problems such as transistors or coils?
@ASUSproz One thing to double check,,, Did you make sure the polarity marks went into the correct hole for each capacitor? They usually mark the minus (-) side of each little can. Other than that, I would check for solder bridges (drops of solder that accidentally are shorting the connections) or loose solder joints.
@getonthetubedude I have a VX922 that had the same exact issue. This video is awesome!. The monitor opened a little different and I had to hunt around for 105 degree C caps. I had 2 470 and 1 330 with crowns. I have never done anything like this before. Caps must have + and - sides and MUST go in the way they came out. My F#$%ing monitor works again!!! F#$k Viewsonic!!!!!
Yet another satisfied customer. I have had my "broken" VX924 sitting in my office for about 2-3 years now. I just could not bring myself to trash it. I just soldered on 2 new caps and it works. Unfortunately, I don't need the monitor any more. I suppose selling it is much better than trashing it though!

My VX912 started doing the blinking thing. Whipped it open, took the two bulging capacitors out, popped round to Maplins(UK) but they only had one 470μf25v in store. So I bought two 1000μf25v ones at the hugely satisfying cost of £0.84 ($1.29), popped them in and switched it on, no more blinking!
I had similar problem, screen would go on/off repeatedly when resolution changed to higher on Wins startup. I found all 4x 470uf/25V bad so replaced them with 33V ones giving them some headroom. How ever the main problem could be coz the caps are so close to the heat sink. Could add small fan but the new caps should last couple of years enyway. Hey great vid too!
@garagecrap you are partially right, theres two reason these fail, first is low grade caps, second is too close to a heat source as you mentioned. the heat sink bakes the electrolyte and shortens the life. I used hi temp caps for this reason - I just did this repair, and noticed there was plenty of room on the board to put these caps elsewhere, but they want us to buy more monitors and you can guess the rest-lol crooks --
I had the same problem with a vx922 (not a vx924 like this video) and i replaced the 470 μf + 25 volts capacitor with a 1000μf + 25 volts capacitor and i followed these steps and it now works perfectly. And i only changed one capacitor, the one that seemed more suspicious
Good job mate, cheers and thank you for your effort making this video, it really helped a lot of us
@punfs I never guessed so many people would take advantage of this. I am really gald I took the time to put this Up! I had just got my FlipVideo camera and wanted to try a quick production. The whole video took me about 2 hours start to finish. Thanks for atking the time to pass your results along. The more people who do this will motivate others. It really is pretty easy, even if you aren't that handy or whatever.. Thanks again!
@getonthetubedude Hey thanks - Just replaced all the smaller power supply caps on my Viewsonic VA912b and it works like brand new-!! Five of seven caps were showing bulges, so just replaced all but the huge one that im told never fails. Used hi temp caps from parts express and couldnt be more pleased I didint have to buy another monitor - thanks, Mike
@getonthetubedude Dude---You saved me a ton. I have never done any repair like this before but it worked like a charm VX922 opened a little differently and I had 2 470 and 1 330 cap bad. Had to hunt for 105 degree C caps but they worked perfect. You are awesome!!!!!

@handyman6042 go back and check all of the connectors to ensure they are all seated properly. There was one under the large piece of foil tape (towards to of monitor) that wiggled loose on me and picture came up fine.
@punfs I didnt see him put the little hex bolts back in that hold the external video and power connectors solid in the cover-- these not only provide a place to thread the video connector thumbscrews into, they also keep the connector leads on the board from being dislocated when plugging the cables in and out. Maybe I just couldnt see it in the video-- either way, I just did this on my VA912b viewsonic and now its up and running like new again - helpful video! thanks, Mike
@punfs No kidding, I know a guy in Arizona who's started taking monitors in for repair to make a few $, & hes flooded with work -- easliy 2/3 of the ones he fixes have this same issues. Indidentally the monitor I fixed a month ago is still working fine. Oddly enough, I have CRT televisions that are almost 20 years old and have never needed the caps or anything else replaced -- tells me the quality and location of the caps in these new monitors and TV's with this problem are suspect
Awesome tutorial. But I have a question. Is it possible to take capacitors from let's say, a mother board and put them into a monitor? Or how about a spare Imac capacitors for it's monitor and place them into my monitor that I'm planning to repair?
After replacing 6 bad caps on my VX 922, blinking power light is fixed but, still no image. Have you found any other components needing replacement, perhaps on the converter board?
AWESOME I have a viewsonic VA1703wb came on for 2 sec then nothing.Keep in mind I have never done anything with eletronics in my life beside hit power button I watched a few vids on here borrowed a soldering gun 4 dollars in caps and 3 hours later[anyone who knows what they are doing prob half hour 45 min]like BRAND NEW.The first thing I have ever done correct woohoo
Have the VX922 blinking light syndrome. Replaced the 6 bulging caps on the PSB. Now, no more blinking light but no image either, just a quick flicker and then black.
my green powerbutton does the flashingthing, but only when it goes into native resolution on the DVI-connector, the VGA still works fine, is it still bad capacitors then?
Thank you soooo much! I just repaired my Hanns G HX191D for 1,43€ :) It is quite similar, the main difference is that the case is harder to remove. Instructions for that: fixya.com/support/t1472096-open_hanns_g_monitor
I had to buy 5x 470 25V and 1x 470 10V capacitors. They were very cheap @ Conrad
To bad my Father passed a way Electronics was his trade! never learned much at the time but I must have picked up some, now I know I cant run to Dad lol. OK not much people would show honest info like this, I got a LCD monitor I guess they all work on a same principle and if one cant find same cap then I recall that u can use not lover but higher cap in its place, I am learning and will give my monitor the same thing here it is doing the same jcards thnks u Good Man!
hello thanks for this instructional video i have a viewsonic vx922 i have followed all the steps now am on the step that you have to identify the bad capacitors but it seems like all my capacitors are domed up apart from the tiny one that is next to the cylinder like battery thing i dont know what its called haha. so i dont know if i have to change most of them ?
Never had so much trouble taking a casing off since i tried to take apart a laptop.. Took out the 4 screws and the things still won't budge and now I'm damaging it with screw drivers. ARG FINALLY IT'S DONE. And with only several scratches and a hurt thumb.
Hi, Great Video. I have a VX924 with similar problems. The Green light is not blinking.....I get a strong electrical burning smell from the monitor and the PC image just appeard for a second then disappears leaving a blank screen. Any ideas on how to fix this problem?
All 6 Capacitors were blown. Most of the damage was underneath when you took them out. Went to Jaycar(Australia) and bought Capacitors, soldering iron and solder for $31.12
For mine VX922, it required
X1 10v 470HF
X3 25v 470HF
X2 10V 1000HF
As per video. push out pins with hot iron. Pushed new ones back in while heating blocked hole. Did not need really need to add more solder.
Just finished this fix and everything went well. Excellent vid. Remember, you must go into the monitor to know what capacitors to order. In my case there were three blown 470uf 25v caps which I picked up at radio shack for just a couple of bucks.
P.S. Dual monitors FTW. Now if I only had a better vid card....Radeon 5970 outta do it ;)
I recently repaired my Viewsonic VX922 using this great video tutorial. I had 7 blown capacitors, easily distinguished by the rounded domes on each bad capacitor. As I unsoldered each capacitor I kept track of the type (example: 1000 uF 10V) and the location (example: C244) on the circuit board by writing them down on a sheet of paper. The board clearly marks the negative and positive for each capacitor. I ordered the capacitors on eBay, other types were: 470 uF 25V, 470 uF 10V. Hope this helps.
@kryptiea Great question! They all have small numbers on the side, and these will vary between models. The "bad" capacitors will have a round "hump" or "dome" on the metal end. Read the numbers on the side of these parts and buy your replacements to match. The numbers are values for "capacitance" (uF) and Voltage rating (V). Also make sure you are getting a PC board capacitors (Both wires come out the same end) hope this helps, Good Luck !!
Two of them were blown from the bottom, other had the top domed.
Had to drill holes through bottom plate cause my 1000mfd 25v caps were way to large, mainly too tall, covered the opening with foil, and here it goes, works flawlessly, screen seems brighter.
I have a problem with my LCD monitor. when i hit the power button, the image shows then it goes away. i change the capacitors like in the video but no luck still does the same problem. HELP thanks
Where can I buy these capacitors? I have a Viewsonic VX924 that did the same thing so I just bought a new monitor, but since I found this, I'd like to get that thing up and running again. Thanks for the video!
Thanks so much for the response. Note at 3:24 the bad capacitors will have a "domed" shaped swelling on the top from the pressure inside. Note the value and the voltage rating on the side and simply go to ebay search. In my case i needed 2 pieces 1000uf at 16 volts. ebay ID dementg sells these very cheap. I paid $5.49 total to fix a $125.00 monitor !!
Sure they, are power capacitors (pronounced ka-pass-a-tor) See above reply for details on how and where to replace them. I am told that the bad ones are mostly caused by a case of industrial espionage where one Chinese company leaked a "fake" formula for the chemicals used to make these parts. The "fake" fomula contained damaging chemicals that eventually destroy the capacitor!! Hence, any company that copied the bad ingredients ended up with junk parts!

I just wanted to thank you for posting this video. I just had the same problem with my Viewsonic monitor; mine was a slightly different model but looked the same. I found three caps that looked bad, replaced them with new ones, and the monitor works again!
Thanks so much for sharing this info!

I fix my screen a year ago with this.
But recently, it does the same thing. I disassemble it, but... all capacitors are fine !
Any idea ?

@Eapix Capcitors have 2 numbers on them: capacitance in uf and a voltage rating. Replacement capacitors need to match the capacitance of the bad capacitors, and the voltage rating needs to be as high or higher than what you are replacing. Electrolytic capacitors have polarity (+ and -), and it is essential that you put the + and - leads into the proper holes. Make a drawing noting polarity before you remove the bad capacitors.

@HabsCabs888 No. You must unsolder the bad capacitors and solder in new capacitors. Search YouTube for "unsoldering capacitors" and "soldering capacitors," and you will find multiple videos.

My capacitor seems to be fine. But the green blinking light happens and the monitor flashes. The capacitor has these black dots on top but not domed up. Could it be something with the power cord? I have a 14-inch Monitor ProView. Any help? Im 14. This happened about a year ago when the power went out probably and the fuses went out.The capacitor is 470uF 25v.

@cozykris Hard to say exactly. It's always easier when you can see something physical wrong on the board. It's a little like being a detective! What doesn't look exactly right? Are there any parts that look burnt? Or look like they have been extremely hot? There is still a good chance it's on this board.. Hope this helps!

@getonthetubedude Hi can I ask you where one can buy a tool that opens thin monitor cases? I have a monitor that does NOT have any screws. It would need to be pried off. I don't want to mar it (butter knife) in any way if I can buy a tool to do it right.
ar3582 2 months ago
@ar3582 My Viewsonic monitor had a screw in each corner of the case with several fragile plastic catches along the sides. After removing the screws, I pried off the back as carefully as possible with a thin-bladed screwdriver, but I still broke several catches, as did the person who told me how to open such cases. It is better to break a few catches than to leave the monitor unrepaired. Use a few strips of clear packing tape to hold the case together if necessary.

Many thanks - replaced all six capacitors on my VX922 monitor and it's now working fine. It was a bit difficult to separate the plastic casing - you need to lever the casing outwards to release the catches - and there about three each side. And reconnecting in the circuit board needed some manhandling to line up the plug. So patience, care, and a bit of force is needed! Thanks again for posting the video!

Hey, I want to thank you for the video post. I have a VX922 and was having the green blinking light of death. I popped the case and all but the 400v cap were showing signs of bad bloating. I replaced just the 470 caps as they were the only ones available and my 5 yr old monitor is no longer dead. THANK YOU SO MUCH!! Not only have you given my monitor a new lease on life, but now I have purchased the gear for a home business. THANK YOU! :)

Just wanted to chime in and say thanks. I have had two ViewSonics (they are both Q20wb models) for a while. One has had this problem for a year or two and I just never investigated the problem—it sat around gathering dust. Yesterday, the other (my main monitor) just stopped working and its power light is now a very dim yellow. I have no idea what the problem is, but I'm going to try swapping out the "recently broke" power supply into the "ago broke" one to see if the green light prob goes away.

I turn off and then on again the monitor with the power on button and then it turns on again and after that it does the same thing. I replaced a damaged capacitor but it didn;t solve the problem. Could you give me any idea of how to solve this. Thank you in advance.

I went to Fry's Electronics and picked up everything I needed for only $20 to complete the repair. Thanks to this vidoe I saved my $240 monitor!!!!!

Hello there. Thanks for that video. It helped me fix a ViewSonic VX724 which was almost the same as the one on your video. There was no image and a friend of mine was to throw it to garbage. Cost me around 5 dollars of capacitors and tada... and about an hour work. The only thing is that once in a while, it blinks. There is like a camera flash in the center of the screen, but it keeps on working well. What would you think is the problem? Thanks for answering.
MrKarbo51 1 year ago
Confirmed that this works for VX922. Replaced all 5 capacitors in the row shown in the video (all next to each other on one corner), and the one in the center of the board. The smallest cap on the board wasn't bulging up, so I did not replace it. I used:
(4) 470uF 35V 105 degree caps
(2) 1000uF 35V 105 degree caps
The 1000uF caps I used were slightly larger in diameter. They were rated to take higher voltage than stock 10V caps. Thanks for this video, the fix saved my favorite monitor!

There's a smaller one labeled 470 micro-Farad 10V that looks "domed" as well, so I'm going to replace all four. If I don't post again, it's because it worked. Thanks in advance!

@lite1979 Just as a follow-up: I borrowed a soldering iron from a friend, bought some solder and some copper braided wick just in case (to soak up extra solder). I was able to remove all of the bad capacitors by heating them up - got a little messy and got kind of close to some other solder points, but didn't melt them. I'm posting this from the fixed monitor right now. I used a nail clipper to clip the long ends off the new capacitors. Ebay is a good place to find the capacitors. $13 total

thank you for your videos. The problem is i have replaced the capacitors in the power supply of a Samsung monitor (Power Board IP-35135B). I even replaced the ones that looked fine in case they couldn't hold up charge anymore. Still no success. Back light still doesn't lightup. I know for a fact its the power supply problem because i have tried it with a different known working one and the monitor lights up.
Do you have any solution? Could it be other problems such as transistors or coils?
ASUSproz 1 year ago
@ASUSproz One thing to double check,,, Did you make sure the polarity marks went into the correct hole for each capacitor? They usually mark the minus (-) side of each little can. Other than that, I would check for solder bridges (drops of solder that accidentally are shorting the connections) or loose solder joints.

@getonthetubedude I have a VX922 that had the same exact issue. This video is awesome!. The monitor opened a little different and I had to hunt around for 105 degree C caps.

You sir, are an absolute legend!
My VX912 started doing the blinking thing. Whipped it open, took the two bulging capacitors out, popped round to Maplins(UK) but they only had one 470μf25v in store. So I bought two 1000μf25v ones at the hugely satisfying cost of £0.84 ($1.29), popped them in and switched it on, no more blinking!
And all in less than an hour, Fantabulous!!!

I had similar problem, screen would go on/off repeatedly when resolution changed to higher on Wins startup. I found all 4x 470uf/25V bad so replaced them with 33V ones giving them some headroom. How ever the main problem could be coz the caps are so close to the heat sink. Could add small fan but the new caps should last couple of years enyway. Hey great vid too!
garagecrap 1 year ago
@garagecrap you are partially right, theres two reason these fail, first is low grade caps, second is too close to a heat source as you mentioned. the heat sink bakes the electrolyte and shortens the life. I used hi temp caps for this reason - I just did this repair, and noticed there was plenty of room on the board to put these caps elsewhere, but they want us to buy more monitors and you can guess the rest-lol crooks --

Hi, Great Video. I have a VX924 with similar problems. The Green light is not blinking.....I get a strong electrical burning smell from the monitor and the PC image just appeard for a second then disappears leaving a blank screen. Any ideas on how to fix this problem?

Fantastic. My monitor is now working.
All 6 Capacitors were blown. Most of the damage was underneath when you took them out. Went to Jaycar(Australia) and bought Capacitors, soldering iron and solder for $31.12
For mine VX922, it required
X1 10v 470HF
X3 25v 470HF
X2 10V 1000HF
As per video. push out pins with hot iron. Pushed new ones back in while heating blocked hole. Did not need really need to add more solder.
Interestingly the monitor does appear brighter.
thanks again

Just took mine apart, same exact problems, blinking green light. I got 2 1000uf 10v capacitors that are domed.

thanks a lot I got the same problem and I thought it was something to do with video card , but now I got to try this ....

Just finished this fix and everything went well. Excellent vid. Remember, you must go into the monitor to know what capacitors to order. In my case there were three blown 470uf 25v caps which I picked up at radio shack for just a couple of bucks.
P.S. Dual monitors FTW. Now if I only had a better vid card....Radeon 5970 outta do it ;)

I recently repaired my Viewsonic VX922 using this great video tutorial. I had 7 blown capacitors, easily distinguished by the rounded domes on each bad capacitor. As I unsoldered each capacitor I kept track of the type (example: 1000 uF 10V) and the location (example: C244) on the circuit board by writing them down on a sheet of paper. The board clearly marks the negative and positive for each capacitor. I ordered the capacitors on eBay, other types were: 470 uF 25V, 470 uF 10V. Hope this helps.

Where do you get replacment caps? I have the same monitor with the same problem and want to attempt a fix.

I pulled two 470uf 25v capacitors from an old MAG 15 inch monitor with a bad LCD and soldered them into my Viewsonic and it seems to work so far.

How do you know what capacitors to use and where to get them? Are they all pretty much the same from monitor to monitor?

I have the same question.
MrJosiahT 2 years ago
@kryptiea Great question! They all have small numbers on the side, and these will vary between models. The "bad" capacitors will have a round "hump" or "dome" on the metal end. Read the numbers on the side of these parts and buy your replacements to match. The numbers are values for "capacitance" (uF) and Voltage rating (V). Also make sure you are getting a PC board capacitors (Both wires come out the same end) hope this helps, Good Luck !!

Just fixed my VX922, by changing 6 caps.
Two of them were blown from the bottom, other had the top domed.
Had to drill holes through bottom plate cause my 1000mfd 25v caps were way to large, mainly too tall, covered the opening with foil, and here it goes, works flawlessly, screen seems brighter.
Thanx dude.

Thanks for the video. My VX924 had resolution problem which it won't go below 1024x768. Now it works like when I got it.

Where can I buy these capacitors? I have a Viewsonic VX924 that did the same thing so I just bought a new monitor, but since I found this, I'd like to get that thing up and running again. Thanks for the video!

Thanks so much for the response. Note at 3:24 the bad capacitors will have a "domed" shaped swelling on the top from the pressure inside. Note the value and the voltage rating on the side and simply go to ebay search. In my case i needed 2 pieces 1000uf at 16 volts. ebay ID dementg sells these very cheap. I paid $5.49 total to fix a $125.00 monitor !!

whats the name of the little black things we have to change?? We have the same problem here!
Tchew83 2 years ago
Sure they, are power capacitors (pronounced ka-pass-a-tor) See above reply for details on how and where to replace them. I am told that the bad ones are mostly caused by a case of industrial espionage where one Chinese company leaked a "fake" formula for the chemicals used to make these parts. The "fake" fomula contained damaging chemicals that eventually destroy the capacitor!! Hence, any company that copied the bad ingredients ended up with junk parts!
