Backlight not working intermittently. Looking for LED part source.For several years, I’ve been following threads on LED backlight problems. Many have tried replacing parts, but the one...
Respuesta a "Backlight not working. Camera, Sound, USB, and LCD are functional."I’ve been trying to solve this same issue for several years. I can’t recall where I found the info, but one possible problem is that the LEDs have worn out and there is a circuit that turns them off when they run too long. You’ll know this is the issue of it works intermittently. After turning the monitor off for several minutes/hours/days, the backlight will work again for a while, but eventually die again. It gets worse over time till it just won’t light up anymore. The problem I’ve had is finding replacement LEDs. Every few months, I do a search on Alibaba hoping they’ll turn up. (I once bought a set, but it was mislabeled and was actually LEDs for the larger display. If anyone wants them, please contact me!) I believe there was a solution to circumvent the circuit also, but you lose the capability to adjust illumination. If you learn anything more or find a source, please share! Good luck!
