Display get brighter after some time VA1912WB 19'' LCD

Look at the main power board. Near the black plug that goes to the audio board you will see a round metal disk with the number 100 on the top. This is a 100uf capacitor. In all likelyhood this is the problem. We recently had 12 go bad at work and we fixed 10 of them by replacing this cap with a $1.29 electrolytic cap from Radio Shack (this cap looks different but works the same). Just remkove the old one and surface solder this one in (pay attention to polarity +leg to + mark on board;)

I have two broken VP201 monitors with different symptoms. One was black screen green light - like yours. The other was purple speks flying all over the screen., purple tint.

I swapped the power supplies and display boards, both monitors had original problems. I swap the inverters and the monitor which was black screen now appeared to work okay - but slightly pink and the monitor which was purple speks is now black screen.

I would therefore assume that both my inverters gone, one being on it's way out. You probably have the black-screen case.

Hello,

You have a very common problem that happens to many LCD monitors after 2-3 years of use. Your monitor has blown the power supply that controls the backlight bulbs. Go to our web site at: www.ccl-la.com/badcaps.htm and look at the pictures of what blown capacitors look like. Open the back of your monitor and replace any of the parts that look like the ones in the pictures and you should be back going again. Be sure to usehigh temp (105c) replacements. Resolder them in with the side polarity stripe going the same direction and the old one came out. The values of the bad parts will be marked on the sides of the ones you take out, they can be ordered online from us or several other places, the one from Radio Shack are not suitable for use in the high heat inside on the monitor and will soon blow again.

I hope this helps, if so please rate my solution.

If you have more questions just ask.
