From what I have determined through testing, the screen will flicker (more accurately it appears like an old film). This occurs when the main processor is in use. The flicker goes away when watching a dvd. OS is 10.5.8, same issue occurs with 10.4.11 This board has the known ram slot issue. How can I fix the flickering?
Hi! I'm wondering if this happens in all screen resolutions and color depths? You might try switching to a different resolution just to see. While unlikely the answer (due to the fact you've tried two different operating systems), I have seen machines go into odd screen resolutions when a DVD is played, or when external video is used (I assume to accommodate the limitations or specs of the external image). Also, I always do PMU and PRAM resets on malfunctioning machines, just to rule that out, because funky settings in PRAM can cause any number of problems. Hope that helps.
your anwer is,wait for it ........... there is nothing you can do about the
Apple guys diasbled the solution url for that problem because of the product line factory problem they failed to fix.and that is the reason why you no longer find them on the shelves,they were dicontinued for that same reason.Shame on you Apple
