Led issue or board?
toshiba 50l711u18 back light turns off after 5-9 minutes of use. I can see picture with flashlight. I can’t see any light from air vents when black screen. I have factory reset. Unplugged for 10 min. Nothing seems to help. Would this be a board or led issue
Is this a good question?
It could be either or both. If you have backlight for 5-10 minutes it tells me that it manages to drive the LEDs however, something in the circuit cannot sustain the power delivery. I'm guessing capacitors that are drying out on the backlight circuit.
