Jvc tv av25vt14 have sounds but no picture black osd


check first the rgb drive voltages coming from uoc it measures 2.2vdc not 0.542vdc.If your multimeter reads 0.542 your crt screen looks like a dim picture with a retrace line on it. Replace ic 351 which is tda6107, cured the problem.

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.

No Picture


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.

It was working fine then no picture dark sceen sound work fine


More information is required. Your backlight is lit (screen not dark) but I need to know what you have connected to the TV (your sources) and how they are connected. Does the menu/OSD (on screen display) work?
