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.

Do you mean the JVC Logo keeps appearing?

If so, call JVC for the software update. I believe it may even be posted on their site. You can check in the TV menu to verify. You should have F108 or higher.

If the update doesnt apply, you need a Digital PWB for the TV because it is defective.

I am deeply sorry but you will need to replace the backlight bulbs. These are not available.

Look on Ebay for a 32" JVC with a broken LCD Screen. Buy it and use these bulbs to fix your TV. I am sure there will be a few good ones in the broken TV. It's that or list it on Ebay for $50 and expect to get about 200-300.

LCD Panel repair for this problem is $500 for parts so you are stick with repair yourself or sell.
