Horizontal lines on display unless lid half closed
This is my work computer that lives in my drawer. No wear and tear to speak of (other than opening and closing the lid). Opened the lid mid-day one day and horizontal lines completely cover the display.
If I slowly close the lid to about half way, the lines will disappear.
Only to reappear when the lid is opened again. Obviously a connection problem. This is a work computer and the repair shop quoted work $3000+ for this repair. Ludicrous. Also, no apple care was purchased so this barely-more-than-a-year-old top of the line Apple computer is suddenly worthless.
I'm not afraid to open the case, but could someone direct me to the cable that I should unseat and reseat, or perhaps even replace?
Any help greatly appreciated.
Ist dies eine gute Frage?
