SOURCE: Picture blacks out after a few seconds after turning on the tv

Anytime an LCD has a shade of pink, that means the CCFL lamps are about to go out. Now that you have a black screen, I'd say you just need some new bulbs.

SOURCE: TV screen went dark, but sound still there.

your backlight burnt out, this will be a maybe several hundred dollar repair. the screen is backilt by a very expensive flourescent light, without that light, the screen will be black.

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.

Sound like the power supply board has gone out .Unplug the tv for 2 or 3 minutes and plug it in again and try to turn on. Some times they will come on .But It sounds like the PSB is going out .
