LCD TV repair

[ChaseK004]

how do you safely remove the capacitors .. w/out getting shocked ??

[fatrat1able]

that happened to me,brand new tv,125$ to get fixed,,found another 20" gonna fix it myself or try,same problem , cool thanx for the view,,

[GhostLaughingMan]

LMFAO as soon as i seen the 2 caps blow out i knew it was a Polaroid 

[SuperCk2000]

Also where did you find the parts ? 

[porousorifice]

@SuperCk2000 Ebay.

[SuperCk2000]

Did you use a soder gun to glue in the new parts ??

[porousorifice]

@SuperCk2000 yes a soldering iron.

[canadiantechnologist]

oh boy....you must come from the states...yes you repaired you screen...but you were very lucky....a towel is not the greatest way to dissipate static...plus I didn't see you wearing any anti-static protection... no wonder we buy our electronics from Japan...LOLLL

[porousorifice]

@canadiantechnologist Yes from the states, this is a common problem with these units. I believe it's the poor quality Chinese caps, possibly under rated values on the voltage. As for protection, you can't see in the vid. but i am wearing a condom! LL

[Abacustools]

Hi all very good info, but my Sanyo TV doesn't show any blown caps, are there any other tests to run ?

I would really apreciate for your help.

[erest12]

I wanted to ask, I have a problem with p42 vizio hdtv picture because I do not give me sound but appreciate it for their valuable help.

[southerman57]

I have a poloroid hdtv that has no picture took apart and see one of the capacitors looks bad but it is 10uf450v nobody seems to have run into this size is this dangerous to replace

[porousorifice]

@southerman57

The short answer... no. Make sure it's not plugged in and to be safe take an insulated wide bladed screw driver or somthing similar and short between the cap terminals to discharge(prob. not charged but saftey first). Then unsoldier cap. take note which lead is which NEG. is usually marked on the outside of the cap.

Here is one of many places that sell that cap.

Hope this helps.

[lunexar]

i have the same make model of this tv that i have had to do this repair on 3 different occasions. this being said, our power recently went out and the tv no longer even has the l.e.d. come on for standby mode and i am not sure why there is no power at all. how do i go about fixing this , is it a common problem?

[porousorifice]

@lunexar No power at all is not that common, being that you suffered an outage it probably suffered a voltage spike. I would start with the point at wich power is supplied to the board. i dont remember if this model has a board mounted fuse but check that as well as rectifier diods, exsessive forward bias voltage can kill diods.

Hope this helps.

[Zundwig]

I have a friend. He owns a 40inch. Sony Bravia kdl-40v4100. Lightning struck his house, and now the TV doesn't work. How would I diagnos the problem? And what steps should I take to fix it, without taking it to a TV repair store?

[porousorifice]

@Zundwig I believe this model has a diagnostic blink code function via the power led. plug in set to wall outlet (not a power strip) manually press the power button and count the number of times the power Led blinks in series, the cycle will repeat. Somtimes there will be more than one code (ex: 5 blinks pause then 7 blinks pause and repeat). This may occure as soon as you plug in the set.

If there is no Led or signs of power, i would check the main power board for a blown fuse.

peace

[8271394]

@Zundwig I would check the whole thing for any browning on the power board. Let alone maybe the fuse yes and the capacitors.

@gcampton666

You complain about me leaving a comment here? you are NOT the author, so you can cut that shit right out.

You shouldn't apologize to people for being rude, just DONT be rude, especially when you are trying to help someone, that's all.

At last, since i really don't wanna spend more time here, thanks for trying to help me.

Take care now.

[godwithin060988]

@gcampton666

First off, NOBODY ask YOU you F%#ktard so if you are gonna reply to my post then don't give me that additute and call it a "joke", what are you a CLOWN?

And second, instead of asking people to go buy a book you could have just EXPLAINED it you moron, people that come here ONLY want to figure out how to do a LCD TV repair and not how to make a F%&king metal guitar.

And if one decided to carelessly Play with the PSU they wouldn't be here in the first place, use some LOGIC will ya.

[godwithin060988]

@gcampton666

Oi, oi, watch your typing, i just asked for something that would benefit a lot of people, since he decided to make a video, at least, he should have put some instructions instead of a song.

And by the way, i hope you are realizing you are replying to a 3 MONTHS old post, you don' think that i figured something out until now do you!?!

Now get lost.......

:(

[FunAndJokes]

Hey i have a T.V with scratches on the screen but the picture is not affected at all can i replace the screen with any plastic board that fits?

[porousorifice]

@FunAndJokes I sent you a p.m. hope this helps!

[chucaswatjfan]

i got excited when i thought this was going to be an easy fix. i found this tv in the dumpster at my apartment complex and decided it would be fun to toy with it. it had no power what-so-ever and after my little research i found that most people are replacing this z9 diode. i unsoldered the diode and checked it with my meter but unfortunately it tested good :-/ now im off to do a little more research. any suggestions would be great.

[porousorifice]

@chucaswatjfan Z9 diode is prob. a zener diode used for rectifying ac voltage to dc, so it sounds like your starting out on the right track. There should be four zener diodes that are used to make a bridge rectifier along with some capacitors for filtering. Check those caps. for signs of leakage or bloating as well as any other caps. in the main power circuit. Alot of times they will solder a fuse on the board so check for that as well.

Hope this helps, stay safe and peace.

[WESKER96]

I opened up my element electronics TV, but I forgot how to put it back together.... it's still lying on my desk for the pass couple of weeks. >.>

[Harpsonic]

Removed rear plastic and metal cover. Unplugged 4 connectors on pwr supply board. Removed 4 screws of pwr sup. board. Used solder sucker with soldering pencil to desolder two 1000mf, 10V caps. These CapXon caps fail maybe because of working voltage (10 volts). Installed 2-1000mf, 16V ones. They were larger than originals and didn't fit into the space so I used silicone caulk to glue them down in an open space on the board and ran wires from their terminals to the solder holes in the board.

[Harpsonic]

I followed this video and repaired my same 4 year old Polaroid TV with a black screen and it would not turn it off except by pulling the AC plug at the outlet. Thanks for saving me alot of $.

[Harpsonic]

Thanks

[godwithin060988]

It would have helped if ou TALKED instead of putting on a song.

It is a great video, but for people that dont have as much knowledge as you do it would help if you instructed people what to do.

take care

[rhibac]

i have acrappy lcd 32 inchit turns on green then the lights blink yellow either a quick 2 or 6 times

as i type right now it took me since 2-44 to and its now 3/26 to even get the screen flickering but itstil shuts off as i constantly push the power but from my remote control what could be the issue.

new Tube tv's never had problems like this in under 3 yrs of use IMO

[32ukfan]

My Lcd tv gets sound but no picture.. The picture comes on for like half a second then goes off. I was told it was a Capacitor. I hope thats all it is.

[mikewm9v]

you need a cheap forming tool for the leads , some flux remover and a decent set of electronic sidecutters

[jamo387]

Ahhh, the old Bulging caps. Bastards get you every time.

[djwiplash1]

i have the same tv and it has the same problem.... i fixed the same way...

[porousorifice]

@djwiplash1 Glad to hear you got yours working. Mine is still going strong, these tv's produce such a good picture that they are worth fixing, dispite the fact you should not have to, given the age of the unit.

peace

[Marilynm25]

I have read other comments and answers I will try this, thank you so much for your answers and help! I hope this works, like I said they want to charge us over $150 to fix I have only had the TV for 3 years what a piece of crap!! THANKS AGAIN!

[Marilynm25]

Okay my Same TV is not turning on! The blue light is on and nothing on the screen, for a while I used to be able to unplug the power cord after it warmed up and then I would get a picture and a loud buzzing noise that would go away after a few mins. But now I am getting nothing, what part needs to be repaired. I called a TV repair shop they said something about a module. Please let me know what part so I can get it. This video does not really list parts. Thanks everyone.

[porousorifice]

@Marilynm25 I replaced two 1000uF 10 volt caps. I recomend a higher voltage rating, like 16 volt . a local electronics store may stock them or ebay.

peace

[Logoseum]

@Marilynm25 That's the problem with todays TV shops they want to replace the whole circuit board instead of doing component level fixes like this one.

[bluebeltatt]

nice video! My Vizio VX37L does not recognize HD channels anymore, i get a blue screen and no audio and video icon on the screen. I have an Emerson HDtv that i connected just to rule out the coax system and it picked up the HD channels fine. Is it time for a new tv? should i pay to have it fixed nly for it to go bad again?

[porousorifice]

@bluebeltatt Well it's not a power supply or back light issue. If regular tv and rca inputs work, then it narrows it down to the H.D. circuit. Maby search repair forums sorry i couldnt be of more help.

peace

[changsifon]

my plasma Tv with Heavy Glass screen ( ye is a very old school 42') fall of the table and fuckd up its screen :( can you tell me how much will cost a new screen ?

[porousorifice]

@changsifon I dont have an answer as to the price but for the price, you could probably new one thats larger. I would search the web for pricing before writing it off!

peace

[changsifon]

@porousorifice I have a new problem my Pc Screen (Samsung SyncMaster 940c) have a big problem .I think there is something with the LED's cuz when i start the Monitor it Blinks but after this it becomes dark , I can see the Icons but very smoothly

[hoopfan71]

@changsifon Unless you can find a donor tv cheaply, it's time to get a new tv. The panels are very hard to find or at a reasonable price.

[maxtechjam]

my screen stays blue and my power button or components, hdmi, functions not switching. could it be a power problem.

[flotuss]

My Sonia Bravia flat screen picture went completely red on me, but I can still hear the channels volume. What could be a solution to fixing it? I have had it about 3.5 years.

[porousorifice]

@flotuss can you still bring up on screen menue and see it?

[silvioz87]

my television lcd has weird horizontal green lines on top!

How can I fix it?

please help me

[porousorifice]

@silvioz87 I am not sure with this type of problem. You might want to search web for others with the same issue for solution.

sorry i couldnt be of more help.

peace

[sharwayneg]

@silvioz87 i had that same problem the motherboard needs to be changed ask the company of your tv where you can find one from mine was under warranty it took 45 mins to change because of the screws good luck

[MSTLOM]

YEP! My NUMBER ONE bitch! The Manufactures are PURPOSEFULLY using Capacitors with Voltage Rating far too low. For instance, use of a 6.3 Volt Cap in a 5.0 VDC power line. The 1.3 Volt difference is NOT enough overhead. I always replace the Cap with the next highest Voltage Rating. And the Manufacturers KNOW THIS. But it is all a RACKET. I have saved SO MANY Computer Motherboards and Computer Power Supplies doing CAP replacements and voltage upgrades.

[porousorifice]

@MSTLOM Agreed, it really pisses me off when somthing takes a crap a month after warranty lapses. I understand the if they build a moniter that lasts 20 + years (which i'm sure they can) there brand name would become synonymous with supieor products but would probally not sell as many units due to price. I also wonder how many 40yr old Zenith tv's that worked perfectly have been thrown away over the years !

I have a record player that works fine but i cant seem to get it to work with my CD's !

[MSTLOM]

@porousorifice ....I have fixed alot of electronics where the only problem was dried out Capacitors. Those basic CYBERHOME DVD Players that eventually will not power up have two Capacitors on the Power Supply Board that are crap. Soon as you pull the case and see the Board you can see them.

[dabaddon]

if the picture is dark n color is faded, what can be the problem

[porousorifice]

@dabaddon sounds like a back light issue, look for swelled or blated caps. in the inverter circuit.

peace

[leebee1989]

Is it always this easy? I've been looking on ebay at various ones selling spare or repair, but its a bit of a gamble isn't it?

[porousorifice]

@leebee1989 diagnosing the problem is ussually the biggest part of the repair. Part swapping is easey as it looks, the key is to practice your soldering technique. The caps. seem to be the most common cause of the problem. It is always a gamble so for me the cost of the item in need of repair out weighs the cost of the repair by far.

peace

[leebee1989]

@porousorifice

Many thanks. Will definitely be looking into this.

:)

[xxxffs]

Lol i was like "Woohoo!" when it turned on at the end XD

[satansludge]

I agree with some of the comments about explaining how or why you did this that and everything else. Still a great video. I'm constantly seeing faulty LCD and Plasma tv's at the markets for $20.00 for 32" so I might just take the gamble. What are the top reasons the screens stop, other than wii remotes, pots first, power supply 2nd a rough guide would help me because I'd like to fix this kind of problems, I'd get much love from the family if I brought stuffed LCD's and fix them for under $10.00

[dc51203]

i have this exact same tv ... i love it . but the built in dvd sure has alot of quirks. very interesting video

[nhatz34]

We have the Bravia Sony my nephew broke it by throwing the wii remote on it?! We have the same problem if u turn the tv on there is sound but it was pitch black? If ever were gonna do it our self wher we can buy the new screen??! Anyone can give me an idea??

[porousorifice]

@nhatz34  I'm not sure where to purchase one. Price and avalibility will determin weither repair is an option.

peace

[leebee1989]

@nhatz34

To be honest, the price of the new screen wont be far off the price of a new set.

You might be better off selling the tv for spares or repairs on ebay, then putting the money you get from that towards a new tv. And make sure your kids wear the wii wrist straps!

Hope this helps :)

[2fly4money]

does your 4240 go black w/sound remaining on? here's the fix...remove back plastic cover (3 screws) remove metal cover (3 screws) half way up left side find red LED, next to LED find small dip switch with four switches, move bottom switch #4 to right (on).....replace covers......repair complete....enjoy! Did mine last night, watching all evening, no "black"!

i have a toshiba tv & the screen flickers & freezes & when i bang it, it comes on for a bit then does the same thing then i have to bang it.

any chance of help i was thinkin of a cold joint

[porousorifice]

@MJDJSiddall If banging it helps, just set a hammer next to the remote for quick access! J/K

Yes, sounds like a cold soldier joint but first i would remove cover and blow out the dust bunnys and check it. You may get lucky and it just may be dusty.

My Polaroid TLX 4240B just started messing up. The picture just freezes and won't respond to any command from either remote or side buttons. The only thing we can do is unplug it until it cools off. any ideas ??? Thanks

[porousorifice]

@tworth1953  Hmm, not a common problem that i know of. The fact that it is associated with temp. leads me to believe it may be an electrolitic capacitor as there temp affects there capacitance more so when they are going bad.

sorry i cant be more helpful.

[howie642001]

the main thing is determine your problem as either a bad part or a bad soldering connection

[jaorodeols]

i love repairing electronics devices but i dont know where to buy or order parts like ic's ,transistor, capacitors,resistor and etc?

[WildlifeSeriaLKiller]

there are literally hundreds of places to order parts. You HAVE heard of google, right?...lol I get my caps from Parts Express.

[lindseydancy1]

I have a SEG 42" LCD that keeps going onto standby, even when its only been on for a few mins, Any ideas what could be causing this.

[porousorifice]

The symtom you describe could very well be bad capacitors, as they warm up they can go out of tolerance or even stop working as a cap. all together. The caps. are cheap so if you dont mind doing the labor, you really dont have much to loose. Look for bloated or leaking caps. an replace with same microfarad value and equal or higher voltage value.

What exactly are the caps that you replaced called and where can you buy them and how much on average do they cost. I don't own a LCD yet but I'm guessing that if I do get one then more than likely I'm going to have issues like this. Thanks Jeff

[porousorifice]

@cheyiennerascal I replaced two 1000 micro faurad capicitors. You can buy capacitors online or at electronic stores like radio shack. They cost around $2-$3 each. Online is cheaper!

Interesting music.

Is it always that easy to fix a LCD screen?

[porousorifice]

@0815tobey I am guessing over 70% of lcd's with these symptoms are caused by bad caps.(seems to be the biggest issue), so alot of times yeah it's that easy!

peace

[TheT8T]

I have the Element FLX 3710. They have the same power supply board.

The two caps you showed are bulging and so is the bigger one directly underneath them. So both 1000uF 10v and the 1000uF 35V are bulging. Should I replace them with the same exact size or bigger?

[porousorifice]

Keep the .uf value the same.

increasing voltage value is fine even prefured. Physical size is the only issue.

Make sure you get the polarity correct or the magical smoke will escape somtimes with a bang! LOL

peace.

[TheT8T]

Thanks a lot for this video. It worked as expected. I replaced the caps with 1000uF35v all the way around. Powers up immediately.... Works like a charm... or a TV.

Glad to hear its up and running. A little effort and a few bucks beats having to purchase a new one for sure !

[xtra7765]

Is it possible to remove the screen on my 37 inch vizio lcd tv and put in a new one? I want to do it myself, because i heard you can buy replacement screens at some stores. But does anyone know how?

[porousorifice]

@xtra7765 I am sure this can be done, most lcd's are conected with a few ribbon cables that unplug. If your talking about replacing the ccfl the job is quicker.I have no idea what a lcd screen costs but the price will dictate weither it is worth the repair.

[drwhoeric]

Oh shoot. You replaced the capacitors with the same voltage as the ones you removed. The problem is the circuit is 12 volts and the capacitors need to be at least 16 volts, not 10 volts. These capacitors will probably fail in 2 to 3 years. Sorry to be the bearer of bad news.

[porousorifice]

@drwhoeric I wouldnt be suprised if failure of the same type happens again down the road. Seems to be under rated caps. are an issue with these lcd's.

i got a lcd samsung and it takes a while to turn on..and when it does the screen has a bunch of lines in colors,turn it on and off then the line dissapear what u think is wrong with my tv..thanks

[porousorifice]

This may be a ccfl(back light) on its way out.

Check the ends of the lamps for darkening or blacked tubes where the HV conecters attach.Alot of times they will work only for a bit then go out once they warm up.

hope this helps.

Let us know what you find.

thanx.

can anyone help me i have a flat screen 32 inch polaroid tv, i have one capacitor that is bad on the capacitor it says "10uf450v and it also says HEC" i can't not find this capacitor anywhere i have not a clue about anything capacitors so can someone plz tell me where i can find the same one? or find one that i can replace it with? thanks b4 hand to who ever replys

[rosco25]

Hi, love your video, I need help real bad, can you help to find the problem? I have an LCD LG TV when plugged in the green light comes on but the screen is blank, what component needs replaced in the tv? please please help. Also wot is that piece of music? thankyou.

[porousorifice]

The song is a cover of Queens "love of my life".

As far as your tv, the symptom you describe is the same as mine.I would look for any signs of swelled caps. on the H.V. inverter board (provides power to the c.c.f.l.'s or back lights). Also check for signs of arching on or around the small transformers on the same board.

hope this helps.

peace.

[coondogtheman1234]

I have a Poloroid LCD-2000 TV and its an older one non HD nor widescreen and it wont turn on, I have reason to believe that the power supply brick is dead b/c theres a green light on it and its supposed to be lit and its not and usually these PS units they make an arc or a zap sound when you plug them in and this one didnt. I took apart the PS brick and found nothing wrong. this TV runs on 12VDC at 6.5 amps. any chance of running it off a jumpstart box so see if it really is the PS?

[porousorifice]

I removed "oOMonkeyMagicOo "coment by accident sorry and i agree when in dought replace it!

[porousorifice]

PER: oOMonkeyMagicOo Dont depend on your multimeter to check if a cap is good. You need an ESR meter. If the cap is even slightly suspect, REPLACE it. I have seen a lot of caps that were bulging and still got a good reading or a close enough value from a multimeter. If I left them in place I know the unit would have worked, but I would expect it would have failing shortly after. When in doubt replace suspect caps. Especially where voltage spikes and heat are involved in circuit operation.

[luw1z]

hahahaha he did the lil dance when he saw that it work. i did to! there was a moment of tension back there when it take so long to turn on :)

[jenko701]

I fix these things for a living ,all of these polaroids have swolen caps ,open them up look for the preg looking caps and replace .make sure you up the voltage on the new caps.

[porousorifice]

Agreed, seems as though they used under rated values for the caps.

save a little money and ruin your brand names image?

not worth it if you ask me!

[dankdavey]

yo how long ago did u fix ? I fixed mine about 8 months ago. and now the tv is buzzing and the picture goes crazy. I opened it back up and the caps i put in look fine... any ideas ?

[porousorifice]

Its been 8 or 9 months, still working.

I would inspect the transformers on the inverter board for signs of arcing or burn marks. one other thing is to look for cold soldier joints they will look dull grey instead of shinny silver.

hope this helps.

good luck.

[HFmonster]

dude im having the same problem ive replaced the caps made sure they were put in right and when I turned the TV back on Instead of a blue screen I got a green screen as far as I can tell check your other boards and see if the cap leaked on them as that appears what happened to mine if so try cleaning the boards with rubbing alch. or call a repair man but from what ive read they dont make parts for these tvs any more

[dankdavey]

i re-soldered mine and its working again . for now any way..... fuck Polaroid

[Watcher3223]

Could the problem also be related to those defective caps that were being churned out from Chinese and Taiwanese manufacturers?

I've repaired computers, TVs, home theater receivers, and a pair of M-Audio active monitor speakers because of these lousy caps.

And when I replace the caps, I always make sure to use Japanese makes (Nichicon, Rubycon, Panasonic, Elna, etc.).

As for using higher volt-rated caps, can't beat giving a little extra breathing space, eh?

[deadkennedya1551]

why cant you fucking talk?

[Ibringthetruth1]

nice vid. but i don't like music.

how about some explanation how you found the problem parts.

was your multimeter testing continuity?

[potc420]

He probably didn't even use a multimeter. Could you not see how swollen those caps were?

[milo223]

If you want to test a capacitor you test for capacitance. You look at the micro farad value on the capacitor(looks like a "uF") and if the multimeter spits out a value close to it then its a good cap. Also depending on your multimeter you may have to desolder the cap from the board.

[Ibringthetruth1]

google 'testing caps' and they use a special tester. capacitor tester i think. multimeters usually can't do the job.

[milo223]

it depends on the multimeter you get. My multimeter (Fluke 117) can test caps.

[bogeyman291]

Para los que buscan informacion de como reparar un LCD, este video es la mejor opcion, claro debes de tener un poco de conocimiento en electronica o electricidad, sino consigues los capacitores de 1000 micro faradios 10v y 35v, puedes poner un capacitor con el voltaje mas alto, (no afecta), el valor de los faradios no debe variar.

Yo repare el mio, como dato importante esta tarjeta de fuente de poder, es utilizada en muchos LCDs.

Yo apoligise si esto no lee correcto utilizo a un traductor. Usted es correcto en ese voltaje que valora para el asunto de does'nt de condensador siempre que usted vaya más alto y ellos quedarán en un espacio dado. Creo que la regla general de thunb es de duplicar el voltaje práctico que el componente experimentará. ¡Yo no supe que esta tabla es utilizada en otras unidades. ... bueno saber! Gracias.

I did not know this board is used in other units good to know! Thank you.

Why do these TV all use cheap capacitors?

[assassinblade590]

The hell with the repair, who is that playing "Love of my Life" on guitar?

[tlacue]

thanks for this video. i have the same tv and i think the same problem although mine has started making a strange noise also. any hints on the noise? we have to must it and listen through the surround sound til it warms up and the noise goes away.

thanks again for the slow and deliberate steps in the video. i loved it.

Very common problem, a relatively simple fix if you know what your looking for.

[herebesmewa]

thank you so much for this, i often overlook caps that are even slightly swollen, thinking they were ok :)

[Voodeux]

Ugh....learn to use the camera and edit software. This sux

[Deron3003]

bro you could ad in the info part about ppl needing to have a solder/desoldering kit and maybe a link to a video taht shows it. cuz i bet someone just opened, rip caps off then used a knife to dig a hole and put new caps in lol

[Deron3003]

lmfao i love how you zoom out and show the polaroid...they are such fucking thieves

[telegraphmyass]

Russ it's Todd yea those caps were swollen I work on monitors i have the same problem on them all the time

video poker machine monitors.

[dubhummer75]

my polaroid has the red light that means it has power but when i push the on putton on the remote and tv nothing happens could this be the same problem

[porousorifice]

That is the same thing the one i repaired did.

This could very well be your problem....it seems this happens often.

look for capacitors that are domed on top or bloated.

peace

[DepthPerception84]

where to buy caps? i have a maxent 32" it turns on but no display will this fix it?

[porousorifice]

same symptom as this poloroid.

bought caps from kiesub electronics.(local here in Las Vegas)

common issue might fix your problem?

[DepthPerception84]

cool i don't know what kinda store out here in southern california to start looking in but now i know what to get and what to do thank you so much.

[bluehighlighterfreak]

TRY RADIOSHACK

[DepthPerception84]

thx

[erickskaka]

um am from vagas were did you buy the parts at???

i have the same problem

[wildbill368]

Yea, that was informative?? what were the symptoms and what exactly did you replace...how did you know caps were defective....yada, yada.

[mitsuevo8mr]

i studied electronics and u see how the caps on the top were like push up, that's when u know the overheated and burned inside, is always better to replace them with caps a little bit bigger to avoid tthe overheat, if the overheat that means they are too small so replace it with one with more capacity....

[porousorifice]

symtom was power light comes on but nothing else. the caps had a slight dome on top instead of being flat.

2 caps is all i swapped out easy fix!

[mvlady]

Wow you would not believe but as i was watching this video i was holding the same exact board from pioneer lcd and i have the same problem, i am no electrician but i was suspicious of those 2 thingies and i am gonna go change mynes 2 thanks.

[envisionelec]

Good video. These TVs are not bad sets, but their downfall is the use of poor quality capacitors.
