2004 iMac G5 - Round 2

August 24, 2021

In my last post I talked about the "new" iMac G5 I'd acquired (knowing something was wrong) that had one of the well known/documented graphics card failures. After making that post I ordered a refurbished motherboard from The Bookyard (vintage Apple heaven) but before fitting it, we thought we'd try heating the chip up to see if re-flowing it would achieve anything, I mean hey, we can't make it any worse...right?

Well, after a couple of attempts we achieved......nothing. Actually, I think we made it worse? Oh well, on to fitting the new board!

The G5 is an extremely simple machine to work on which is good thing considering how many common faults they have!

From this...

...to this

Out with the old and in with the new

Tadaa! It all works! It booted right into the last users system which was jarring, they'd left everything on there. It was very clearly a family computer that at one point just got parked (when the chip went bad I assume).

Around this time was when I remembered it's not (easily) possible to boot PowerPC Macs from USB and considering the SuperDrive in this just seem to keep spitting the disks back out, I had to employ the use of one of our iMac G4s and head into Target Disk Mode. See! Hoarding all these old Macs does have its uses!
