Need help with a couple Acer Aspires with no screen

post #1 of 4
Thread Starter 
Aspire 5534's. Both have same problem, the screens don't show anything. If I connect an external vga monitor they both work fine. I put a known good screen in them and still the same problem. These models have no inverters. Is this a problem with the motherboard or video cable? I cannot find any answers anywhere.

Those are LED LCD's. It is most likely the cable then if your are totally sure it is a known good screen. We have a bunch of those Acer models in our company, I work on them all the time. It's usually the screen or the GPU itself. Having two with that same problem is unusual though. When LED LCD's go, they can either be totally dark or all white sometimes.

Wouldn't the GPU cause problems when you hooked an external monitor up?
