We have an LG tv that has sound but no picture. I thought it needed a backlight inverter but parts co. said the model was LED & doesn't have an inverter. So what's wrong.


most likely the problem is if your lg tv is between 40 and 50 inches that the internal LEDS have gone bad typical with LG models you need to replace the LED light strips inside the panel and it is not easy to do unless your experienced with this take it to a shop or see the link below for more info LG 39 LED TV Model 39LN No Backlights Bad LEDs How To Replace LED Strips

I have a 50 inch Toshiba 50L4300U that has no picture but has sound. What board do I replace?


Do this test first. With the TV on normally, shine a flashlight on the screen. look for a dim moving picture.
1) If you see one, the backlight led driver isn't working.
2) If you DON'T see a picture replace the T-Con board.

I have a 50 inch Hisense TV and the picture went out but I'm still receiving sound.... Can you please help me with a fix for the problem?


It all depends what has led up to the problem, however if there has
been no indication of something going wrong,ie. picture getting dimmer, the most common fix is to reset.
First just check all cables are firmly connected. If that does not work then....
Unplug tv, disconnect from cable box, satellite box, any receivers.
Also turn power off to them as well.
Connect everything back and turn on.

Here is a video of other generic problems that can go wrong on any
tv that leads to sound with no picture.

Just put a new motherboard in a HISENSE 50 inch tv, it still has no picture. Only sound. I ordered a new motherboard and installed it a few days ago


In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
