Hi, A friend of mine has an iMac G5 with iSight which has been something of a lemon for a long time now. It exhibited the typical 'dodgy capacitors' symptoms, as covered by the iMac Extended Repair programme. Namely, there were random freezes preceded be screen corruption, weird coloured lines, etc. Unfortunately my friend didn't have AppleCare and the machine's serial number falls just outside the range covered by the extended warranty. After a few emotional visits to the Apple Store (she was trying to finish here MA thesis on the machine and lost quite a lit of work), they offered to repair it for free, which was good. However, after just a day of the machine being repaired, it froze. More screen corruption (usually translucent areas of the screen - menus, etc.) would suddenly turn opaque or completely transparent and then the machine would lock up. I've got the machine here so I could run a few tests and try to isolate some test-cases that'll trigger the fault. Here's the results: - Machine passes all TechTool tests - Gets a clean bill of health from the Apple Hardware Test - Reformatted the machine and reinstalled Tiger from the system restore DVDs. - Applied all system updates In this 'clean' state, the problem can be triggered really easily. Just boot up, open 2 Safari windows and invoke Expose repeatedly. After just 2 or 3 Expose uses, the thing will lock. The entire screen is unresponsive - nothing can be clicked and, usually, windows will lose their drop-shadows. Strangely, the mouse pointer still moves around the screen and the capslock indicator on the keyboard still toggles. Now, I need to advise my friend on what to do next. Since the Apple Store agreed to repair the machine for free even though strictly speaking it wasn't covered by warranty, I'm wondering how they'll react when it's shown that their repair wasn't successful. Would their offer to repair imply that they believed the machine had the same manufacturing flaw as that covered by the extended warranty and as such is worthy of another repair attempt? Has anyone else been in a similar position? What was the outcome? My friend's currently saving for a MacBook and is all but ready to write this iMac G5 off, which is such a shame considering that over the past 18 months or so of its life, it's actually only been functional for about 5 months. Strikes me as quite a waste... Thanks all.
