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 part I don’t see mentioned a lot was just replacing the LEDs.
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. Another giveaway is if it works at full brightness, but will flick off when lowered and illuminate again back at full.
The problem I’ve had is finding replacement LEDs. Every few months, I do a search on AliExpress hoping they’ll turn up. (I once bought a set, but it was mislabeled and was actually LEDs for the 27”. 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.
I’m wondering if anyone can find a reliable source for LED replacements for this particular model. Or if they had any luck rigging some other LED into the monitor. Thank you for any leads!
If I find the original posts again, I’ll edit to add links. Good luck!
