1x 220uF 63v

1 x 330uF 35v

1x 470uF 25v

@cozykris Could be something else wrong. Any other parts look damaged, too hot, "melted" ? Play detective, you may see a clue!

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.

What did I do wrong lol.

@handyman6042 Mark sure the + marks go in the correct hole. Could also be another problem as well. Sorry not sure!

I replaces 2 bulging capacitors on a viewsonic vx910 however i still have the blinking green light . should i replace the other capacitors? or could there b

e another problem?

[getonthetubedude]

@koopa8585 Sometimes they do not show any physical bulging. Yes, I would give it a shot for the few bucks more it's worth a test!

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?

So what and where can we buy the capacitor?

@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.

@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.

@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.
