My volume works, when i turn on the screen there is a change in the screen but no picture. what could be the problem.


The most common reason for this is a faulty backlight controller. This can be due to bad capacitors or a faulty inverter controller board. It is repairable by a tv repair engineer.

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.

JVC TV (LT-32E478) Stuck (loops) in standby mode...? Buttons on TV have no effect... Will not turn off?


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.

Backlight Bulb is out.
You cannot purchase these as a spare part, you must purchase the complete backlight.
Backlight cost is more than or equal to a new TV
You may sell this TV on Ebay (list your exact symptom). Start at 100 you will get about 250. Take this money and buy a new TV.
LCD backlights don't fail often but when they do there are no part available to repair them so you get stuck buying the complete assembly part. This is more expensive than a new TV since LCD prices have dropped so much in recent years.
