27" iMac (mid 2011) DVD player has sound but grey screen image?
My DVD player just started acting up. I get sound and the DVD is playing but a grey screen image only? Oddy, when I go from full screen to a small format the image is visible but only during the transition? Why the transition is complete it's a grey screen with the sound working and I can hear the DVD playing but no image? what's up with this sensor need cleaning ? software? OS? I recently upgraded to Mavericks and am experiencing alot of new problems. Should I go back via TimeMachine?
