    Hi all

    Anyone else experiencing random screen flashing/blinking? it only happens when im using the 9400m.

    The first time i rang support i was told to do a hardware reset (hold cmd alt p+r) and this seemed to solve the problem for a couple of days but now its started again. Phoned up again and i've now got to take it in for a genius to look at.

    Im guessing this is hardware related and not much will be able to happen at the genius bar? Anyone know what my possible options will be?

    I think it's a software issue but I'm no expert, check the threads I posted above. Mine seems to do so also (17" unibody) but it's not noticeable and it doesn't happen often.
