No LCD Backlight after repair
A while back we had a technician working on a Surface Pro 3.
He did a dumb and did not isolate the battery before connecting the new display and fried the backlight on the device. We tried multiple confirmed working displays and all yielded the same result: no backlight. It would seem that the problem is board-level. I am attempting repair, but since there seem to be no available boardview or schematic files available for this device, I am at a loss for where to start troubleshooting.
Has anyone attempted this repair or have insight into this problem?
Ist dies eine gute Frage?
