My lg tv wont come back on the light still on but theres nothin on the
@ak41 we will need to know the exact model number for your TV. We also need to know is you are having sound and which light is on. If you have sound but no picture it could be that the backlight array has failed. Pretty common for LG TV’s. If you have not sound and no video it is possible that this is a mainboard issue. You will have to remove the back from your TV and take a look at the boards. Post some good pictures of those with your question so that we an see what you see. Adding images to an existing question
