Display turns off intermittently, depends on angle opened.
I believe the Apple techs BSed my daughter. They had repaired the macbook under warranty for case flaws and an overheating problem. Replaced logicboard.
After they repaired it, the display has been wobbly and the display will go black or function properly depending on how you fiddle with the opening of the display.
Very random about the exact angle that works.
I think that if I open the thing up that I'll find a loose display connector, or a pinched wire.
It's past warranty now.
Oh, and they tried to tell her it was water damage that she'd spilled something on the macbook. She hadn't.
Seems to me this kind of problem, it's intermittent nature indicates improperly being reassembled after the last service.
Is this a good question?
