I have a JVC LED TV (LT-42X579). The screen goes black intermittently and then comes back after a few seconds. This happens with my PS3 (component) and antenna feed (COAX). Any sugestions?


Hello, do you keep the sound? if you do, take a flashlight when it goes out and shine it across the screen, can you see a dim image? if you do the L.E.D. driver/power supply board may be bad. let me know....tks

Black screen in jvc lt 42e478


If you can see a dim image when you look at the screen at a sharp angle then you most likely have a faulty inverter board or faulty CCFL lamp/s.
Most likely faulty inverter board which supplies high voltage to the CCFL lamp/s.

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.

JVC LT-23X475 flat screen TV


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.

I just tried re-setting the digital tuner, which for the JVC LT-37x688 is as simple as powering the TV on, and holding the chanel down and volume down buttons simultaneously for about 3-5 seconds. The screen will go to black, and the TV will power off. Turn it back on, and you get the JVC logo again as everything re-sets. This solved my problem with vertical colored bar lines vice a picture, and sound.
