Every few weeks or so we turn on the tv, the sound turns on, but the TV remains black. Usually it fixes itself the next day or hours later but this time it hasn’t. Any help would be great.

will serio right now it reads as if you are saying you have sound but no picture. If so, in a darkened room shine a flashlight beam at an angle against the screen. If you can make out shapes, silhouettes etc, you know you have a failed backlight. That could be a bad power board or bad backlight strips. If you cannot make out anything with the flashlight test then it is possible that this is a mainboard, power board or T-con board error. We would need to see the boards so post some GOOD pictures of those with your QUESTION. Also, verify that your TV is a LG 60LM6450 60inch Full HD 3D LED Television
