List Folks, I think my Rev A iMac may be dead. I'm wondering if there is any hope for it. If any of you have any suggestions on reviving it, I'd sure appreciate your help. Here's the situation: I upgraded from OS 10.1.5 to 10.2. The install went fine. Then I upgraded to 10.2.2. Again no problems. Did some other odds and ends on it later that afternoon, then left it on when I went to dinner. When I returned later, it was off. When I pressed the power switch, nothing happened. Then I unplugged it and several minutes later, plugged it in again. This time it began to start up as normal, including the bong, but after 3 seconds (right after the power light changed from orange to green) it shut down. It is now doing the same thing when I try to start it again. Some other facts: 1. I am 99.99% sure I have the correct version of firmware (1.2) installed. Though I didn't check it immediately before installing 10.2, it did check it before installing OS X when OS X first came out, and since firmware 1.2 was released in 1999, it must have that version installed. 1a. It had been having intermittent problems waking from sleep for a couple weeks prior to this. But that had seemed to get better after I rebuilt the desktop in 9.2.2 a week or so ago. (Not exactly sure why that might help waking from OS 10.1.5, but I tried it for superstitious reasons, if nothing else. And the wake up problem did go away after that. Or at least it seemed to.) 1b. It also had had a problem a few months ago with the screen going black for a fraction of a second and then returning to normal. I cleaned out the dust inside and tightened the video connector to the monitor and that seemed to fix it. However, after installing 10.2, I saw that black flicker one time in the afternoon. 2. It has to be unplugged for several minutes (have not timed exactly) for the above startup symptom to occur. Otherwise, when I push the power button, nothing at all. 3. I tried starting from CD (OS 10.2 install CD, Tech Tools Pro, and Disk Warrior all result in no change to above symptom). 4. I swapped the hard drive. Again no change. 5. I took the battery out, let it sit for 30 minutes, and put the battery in again. No change. 6. I tried a CUDA reset. No change.
Can anyone think of something else I should try? Short of a new motherboard, which is what I am afraid it really needs. Thanks for any help!
