    Well today I called Apple support and discussed the fact my i7 had flickering and nano-second blackout problems. I also had one case where the screen went berserk and the dock was at the top of the screen and had grey garbage in the middle as well as other gibberish at the bottom of the screen. The only way I could get it back from this was to use the power button and reboot!

    He encouraged me to send the machine back for an exchange so the engineers could study the problem on my computer. I said that I was afraid to do that for a couple of reasons, mostly because I was afraid that the new one could arrive with some of the other issues discussed here in these forums. (My HD is quiet and no cracks, dead pixels or yellow tinge, etc.)

    I also didn't want to lose all the stuff I updated and changed since I migrated my data to it. (I don't have away to back up the data on this one.)

    So, we discussed alternatives. He mentioned that Apple had found the reason for the screen flickers and that it was a hardware problem, that could be cured with replacing various parts. (I tried to get him to name the parts; however, he didn't name them.) :(

    So, I have an appointment with the local Genius Bar and will be taking the i7 in tomorrow afternoon for a consult and repair(s) at their shop. The shop is only 11.6 miles from my home. So, I'll have to pack this 38 pound ungainly monster up and get it to the shop, which is in a Mall. It might take 5 business days before I see it again! :eek:

    Well I took the iMac into the Apple store today. I had an appointment with a Genius Bar guy. He of course had no knowledge of Apple solving the screen flicker/blackout or other problems. (I think someone mentioned this would happen in another thread.) :rolleyes:

    I sure hope the Mac technician that actually checks the computer is up-to-date on such problems and knows what parts are needed to fix it. So, now I'm sans new computer for 5 to 7 business days during the Holidays! I miss it! :(

    I may try to call the Apple Technician that lined me up for this deal and see if he can check and see if the Tech's at that shop are aware of what Apple has found on this issue.

    So, I'm back on my 17" Flat Screen G-4! Boy do I miss that speed and the Magic mouse! :apple:

    Of course, this particular Apple store is in a large Mall (South Center, Tukwila, WA.) The roads were very heavy with Holiday shoppers and the parking lots were overflowing. The store was very busy as well. It wasn't the best time to do this; however, I had little choice. (According to TV reports this was the busiest shopping day of the year!) :eek:

    Wow! Please keep us updated with the latest info on your situation. I have thought to myself that monitor problems are due to the video cards; and hoping that firmware update would solve them.

    Would love to know if they swap out any parts.
