Chosen Solution
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. Any suggestions?
Your assessment makes complete sense. Its either a pinched cable or loose connection to the logicboard. The Data cable is wrapped around the hinges and can easily come loose or get crimped if not installed properly. I must admit that this repair requires a ton of patience as you would have to dismantle the display and hinges. But it’s the only way to get to the cabling, good luck. You will need this Guide.
