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.

capacitors are most likely to blame here, there are several that most likely are on the power board and are blown if you get them replaced the tv will function normally, the heat can come from the transformer since it is not getting smooth power from the capacitors. it is working very hard to dump the spikes in the electricity. I ups backup power supply rated for the tv's wattage will help smooth power and protect your investment.

SOURCE: lamp going out on jvc flat screen tv 52 inch,how do you change

Versed, you have to open the back panel (cover) to access the lamp. replacing is easy as soon as you can see it. loosen the mounting bolt and pull to unplug the lamp from the SMPS Lamp power supply. Thats it.

Turn on JVC 32" flat screen TV and got the JVC logo then sound and no picture. Then next day, only got the logo, no sound or picture.


There is a way to reset television. I have a jvc 42inch that was just going to main logo screen and not beyond it. If i remember correctly you unplug the tv hold power button for 5 sec on tv then let go plug in and start. If that dont work unplug and then plug and hold power button on tv for 5 sec. It is 1 of those combinations. My tv worked after that. I googled my problem and a website listed that some tvs need to be reset.

JVC LCD TV LT-42X688-powers on, blank screen. no picture,no sound


You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

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.
