Sound but no picture (backlight / LED strip test)

The flashlight test tells you in one minute whether the panel is producing an image with no backlight. If you can see a faint image, the LED strips or LED driver are the likely fault; if not, look at T-con or main board.

T-con (timing control) board: board or panel?

The T-con converts video from the main board into the signals that drive the panel rows and columns. Loose ribbons, a blown T-con fuse or a failed T-con cause image faults; lines that stay fixed in the same place usually mean the panel itself.

Wrong colors or green / purple tint

The TV's built-in picture test splits the problem: if the test pattern is wrong, it is the TV (panel or board); if it looks fine, the cause is the source, cable or settings.
