Hi there
I am struggling with a G5 2.5 quad thats not chiming.
It was an ebay special that was advertised as "Not Working".
However the seller had fitted the incorrect ram and in the wrong slots.
So after fitting the correct ram it chimed and went to the screen with the question mark as there was no hard drive fitted.
The machine booted this far every time I tried it over the next week or so
However there was a real loud wirring sound coming from the inside.
I thought this was the fans but it was not it was one of the delphi pumps sounded like it was running dry?
To cut to the chase I removed the LCS and striped it fitted a new pump and refilled it with a red no conductive coolant its not easy to repressurise and my shed now looks like a murder scene ( Which it could well be as this mac is now dead)
After spending quite a while rebuilding the LCS refitting the CPUs and reinstalling tried to power up.
The power comes on but no chime fans run slowly didn't leave it on for very long as there is an obvious prolem.
There are LEDs lit on the logic board "OverTemp" "Trickle" "PWROn" and another one.
One is yellow and the others are red I'm assuming there is a CPU?Cooling issue?
I used thermal pads instead of paste and I can hear the new pump running it is quiet and there is fluid rushing sound so I assume that is doing what its meant to? Idid buy the same delphi pump type as original but ive read that they differ standard to Apple ones as apple modified them? I am pretty certain I havn't mishandled the CPUs and I marked them to make certain I replaced them the same way they came out. I can only assume either the thermal pads are not working or that the new pump is somehow incompatable.
So is it dead or have I done something really stupid that I've overlooked
What doublely annoying is as this was meant to be a straight forward replace pump and done I ordered some more ram added to the cost of a pump and pipe work and coolant its quite an expensive Hackingtosh case not what I wanted
So would like to get this working again?
Any help is much appreciated
