Chosen Solution

My LG TV 32LB560B-UZ television will turn on, and the sound seems to work fine, but there is no picture. The backlight appears to turn on; the screen is still black but noticeably ‘brighter’ when the tv is on than off, and I can see lights inside when I look into the vents. I tried unplugging and replugging all the wires attached to the boards, but this didn’t do anything it seems. I’m not sure if any of the boards are damaged, so I attached pictures of them below. Any ideas on how to fix it?

Robert  test all the inputs separately. Use a local input source since this can also sometimes be caused by a bad cable or satellite box. If you still have the same issues than the problem is most likely related to the main board. Ultimately it is always possible, yet unlikely until proven otherwise, that this could be the actual panel (failed LCD driver board) Let us know what you find out.
