Hi everyone,
I'm using an aluminum MacBook (circa 2008) running Snow Leopard.
Within the past week, my MacBook display randomly goes blank for varying lengths of time (anywhere from 5 seconds to 10 minutes). The computer continues to run (doesn't go into sleep mode) and the monitor is still powered, but the display seems to lose its video feed. Still illuminated but no images whatsoever. This happens every 5 minutes or so, making the computer essentially unusable. I'm usually able to predict when the problem is about to happen, because very thin, grey lines flicker sparsely across the screen right before it goes blank.
Strangely, opening and closing my MacBook usually fixes that incidence of the problem. Similarly if I plug in an external display, it typically brings the feed back to my laptop, but then the video feed will switch back and forth between the external display and the laptop monitor randomly, occasionally leaving both blank or both functional.
Does anyone know what's going on with my MacBook's display?
