A firmware update might fix it. Call an authorized servicer, explain the symptom.

I have a JVC LT-32x38 that turns on and displays an image for a second but then goes blank and outputs sounds only.


Sometimes the picture goes out but the screen is still lit(backlight on), if totally dark like TV was turned off then check voltages in the power supply board(24v, 12v, 5v) if all ok replace the inverter.

JVC LT 42x688 no picture just sound


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.

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.

It sounds funny but, unplug the set for 30 seconds to allow the TV to reset then see if the problem still is there.
