I have a late-2007 MacBook Pro running OS 10.8.3. Recently the screen will occasionally dim & become pixelated. The problem seems to last for a minute or so & then correct itself. I have run Repair Disk Permissions, Repair Disk & the Apple Hardware Test. No problems were detected.
Can anyone suggest what the problem might be? Is this symptomatic of a display failure? Thank you for any suggestions.
