Hello, I have a MBP (SR, but the one from late 2007, not the current model) and it's developed a problem with the screen. It happens fairly frequently after I lift up the screen after it's been in sleep mode. About 3/4 of the screen kind of fades to white. If I move the screen backwards and forwards, it then corrects itself. But for a few seconds after that, the picture breaks up a little bit before it settles down. I've run a full diagnostics, and it says no problem found. I also tried the thing with turning it off and taking out the battery and pressing the power button for a few seconds - no improvement. I attach a picture showing what it looks like. Anyone else had this experience and found out how serious the problem is? I still have over 2 years warranty in case it's a hardware problem. Thanks.
