LG TV has sound but no picture
pat10151950 could be a backlight failure, bad power board, bad main board or bad panel. Shine a flashlight at an angle against the screen while the TV is on and you are on a channel that has sound. If you can make out shapes and silhouettes it is your backlight. If not then you will have to take a closer look at the boards on the inside of your TV. We will need to know the exact model so we can try to help you further. LG does have issues with failed backlight arrays. If you can, post some good images off your boards with your question so that we can see what you see. Adding images to an existing question
