I have an LG 37LG50 that turns on, and so does the bulb/lamp but there's not picture or sound. Menus don't show either.

the main board is the usual cause of those symptoms. You should be able to get a replacement main board by contacting the guys at

37'' LG lcd tv, no power

I just want to clear things here.
The stand by light will remain on whenever the tv set is turned on by a button on the side of the tv.

Then use your remote to turn on the tv, but wait as it can take 10secs before you get a picture.

relay clicking is a power board failure --- part of the board still works to supply power to the flashing lights--- the lights are related to an error code while in protection mode

Sound but no Picture

Most likely it is the board on the lcd panel. The first question though is, can you get menus? If yes, it is the input module, if no, most likely the panel controller board. There are several makes of panels in these sets, so once diagnosed, we would need to know what panel you have to help further. I can help you figure that out once you let me know if you get menus or not.

Picture goes blank

What type of TV is this unit? An LCD or Plasma?

If it's an LCD, take a close look at the screen with a Flashlight and see if you can see some sort of picture (Almost like a ghost of an image). If this is the case, the backlight has failed.

If it's a plasma unit, you're probably looking at a power supply issue to the panel.

LCD's won't power up

The LCD not displaying a picture may just have a back-light issue. You can verify this by turning on the display, taking a flashlight and pointing it at the LCD then looking at the area that is illuminated on an angle and up close (1" - 2"). If the picture is visible then it is a back-light. You either need an LCD back-light inverter or the back-light itself.
