To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a lg55la6200 led/lcd smart TV. When I turn it on it stays on for about 15mins and then the screen turns off but sound still on. I have done the flashlight test and can see the picture.

The green light comes on but the screen wont light up, meaning the tv wont turn on


hi,
You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

Hello, LCD Problem. I have sound but no image. Black screen. No access to the configuration menu. Someone can help me ??


I think your LCD TV lost back light that is why you have sound but no picture to see it as LCD TV requires back light to present picture on its screen.
Please intimate model and brand of your LCD TV to provide you more info.
