Depends on the make and model of the unit. You did not say what it is. Some have bad LED backlight strips and others have bad inverters or PSU's.

    I have 5 plugs coming from the main board for the led strips. So they still would all go out at the same time.

I have an LG 47LN522-UB LED TV that stopped working after three years and need help diagnosing a problem with it.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ 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.

No picture on mu LG television.


Try the old flashlight test, turn off the lights in the room. Turn on the set and flash a bright flashlight on the screen. Do you see the image or is the screen totally black?? If you see the image, then most likely you have a backlight problem. Verify that you have 24V on the power supply for the inverter
