It seems to be a PSU (Power Supply Unit) problem. When you unplug it and replug, the screen comes on for a moment. That means that the capacitor does not hold charge for long. Open the back and look for bulged or burst capacitors on the module where the power cord meets inside. Replace the whole module if you can not replace the capacitor with exactly the same specs.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

SOURCE: Sound stays on, but no picture- goes black and stays that way.

This unit should still be under warranty and should be taken in for warranty service. Any attempt to access the interior will void the warranty. It is important that a complete description of the problem like you entered here be taken along when you bring the set in for service. This will insure that the servicer be able to reproduce the problem and resolve it.

From your description (and as a servicer), I would be looking for a component that is heat sensitive. These types of problems are fairly easy to locate and resolve.

Please take this in for warranty service and update this when you find out the details.

Thanks,
Dan

TV screen went black, sound is intact, can I fix it?


This sounds like you accidentally hit the input button on your remote. It will either be INPUT or SOURCE on you remote. Turn on your TV and source(cable box) and hit one of those buttons until your picture comes back

No picture


If you look very close at your screen (might need flashlight here), do you see the picture as a black screen? If so, your backlight may have died on the panel. Replacing the inverter board will fix that right up unless the tube (lightbulb) has burnt out instead of the board. Both are replaceable.. Check it out.

My hisense 50 inch lcd tv has picture but no sound.


If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel

Tv works with sound but no picture


Sounds like we have the same problem with a similar Television, I'm attempting to fix a Westinghouse LTV-32w4HDC that has a great picture and sound for about 10 min max. then the screen goes almost completely black(you can make out the red colors somewhat) and the sound is just fine. From other posts on the internet I'm trying to replace the T-CON board. I just ordered one from www.tvpartsguy.com for 25.00 +$10 shipping. I'll post back when it comes in and if that solved the problem. My TV only has four boards in it: T-CON, Main, Inverter and Power board. T-CON seems like the most likely canidate from other posterings and it was the cheapest. Next likely canidate will be the Inverter board I guess. If you have a phillips screw driver and ahve ever taken apart a desktop computer this T.V. shouldn't be a problem ( if you feel uncomfortable, take lots of pictures first so you know how it all goes back together).
