Hi, I'm asking for a bit of help with regard to my intel iMac that has encountered several hardware problems recently, here's the story: iMac suddenly powered off from sleep and wouldn't let me power it back up, so went through troubleshooting with Apple folk and I sent it off to local apple reseller (haven't got applecare) and they replaced the power supply, power inverter and logic board. Great! Got the iMac back and it worked fine... for a few days, then it started to power off randomly, but I could still switch it back on. After this happened a few times it refused to turn back on. Troubleshooting again and back to the apple reseller, I was told it was the power supply (again) and that the original replacement must've been a faulty part. I'm not 100% sure but they may have replaced the logic board again, though they didn't mention it (had to re-authorize iTunes music) Great! Got the iMac back again and it worked fine...except that iMac kept thinking that I had a digital out connected so it wouldn't play over the internal speakers, zeroed the drive to eliminate any software problems and sent it off again after reading that this problem was quite prolific (on MBPs). It was picked up last Tuesday, so it's been almost 2 weeks now and I've been told that the logic board needed is "on order with apple", "hasn't arrived yet, though it's showing as in stock" and finally, the coup de grace: "The part's out of stock and apple won't be getting stock back in until 10th August". Anyway, couple of questions, do I have grounds to request a replacement iMac from Apple as this is getting beyond a joke, complaining to the reseller (Jigsaw Systems) won't get me anywhere as they haven't got stock of the logic board and it's all free anyway (under warranty, no applecare). In other words, I'm sick of being without my computer and need to know what's the best step of action to take tomorrow morining? Phone Apple? Jigsaw? Thanks!
