Picked up an iMac G5 for dirt cheap that was listed as powering up but not outputting anything on screen, now I know the G5 had a laundry list of issues they suffered over the years but as this was a great price and came with it’s original box and accessories it was hard to pass up!
This might be one of the easiest iMacs to open ever, three clever captive screws at the bottom and the back pops off. Before opening it up I powered it on and got the single beep which normally indicates something is amiss with the RAM and lo-and-behold, it doesn’t have any! After a quick eBay search I managed to order some replacement RAM.
Whilst inside I was pleasantly surprised to see none of the capacitors looked like they were ready to party (in a bad way) which seems to be a very common fault on these boards. One of the other common faults is faulty graphics chips (specifically the soldering I believe)…
Well, as I can’t make it any worse, it’s time to disassemble and see if we can re-flow the graphics chip. Watch this space!
