Chosen Solution
A year ago I purchased a new display assembly for this laptop due to intermittent failure of the original one. All was fine until yesterday when the backlight died. I don’t believe the problem is with the logic board, as when I plug in my old screen, which works for a short period of time, the backlight comes on an behaves normally. My question is if there is anything on the display assembly that is worth trying to fix? I know the cable is available so I may try that, but are there any other things to try?
Rarely does the LED’s within the backlight assembly fail. More often the issue is liquid damage to the displays logic board at the bottom is about the only thing I’ve seen in this series. Did you spray your screen with a cleaner? Thats often the cause. What happens is the liquid drips down to the bottom edge and onto the circuitry below it corroding the connector. The fact you swapped over the display leads me to believe this is the case here. Hopefully you haven’t caused any deeper damage. It’s time to get another display and if you need to clean it, spray the cloth instead.
