I have recently received this ASUS laptop to repair. This ASUS laptop does display, but no backlight is on. Tested it on an external display, and it display just fine. I have tried other display with the same connector and got the same no backlight (the backlight does work on these other displays). I also tried the display with another laptop with the same 30-pin connector, there is still no backlight on the original display. I even tried replacing the display cable to see if anything might display on the other displays since the original might have a dead backlight, that didn’t fix it. So I am not sure what else to do besides replace the original display. Is there anything else I should try first?
