There may be some third party shops that will still repair a PowerPC,
but I don't think you can get any repair work from Apple. For David's
sake, I would be very happy to be proved wrong.

It's worth a trip to Apple to get a quote there before one orders the
parts for a DIY.
About a year ago my wife's 2007 iMac blew out its supply. I priced a
replacement from OWC or similar and I was all set to order it and open
that iMac up (very tricky little buggers), but on a whim we dragged it
down to Apple first.
They quoted a price for repair, including parts and labour, that was
about 20% less than the mail order supply alone. So we let Apple do
it. Three days later we had our iMac back good as new.

I'm a PC guy, so I don't know much about Macs, especially the PowerMac,
but I did a quick search & I think a replacement power supply should be
available fairly cheaply if that's what is wrong with it.
I also found a page devoted to how to get the power supply out:

Not easily - I have the equipment but the connections are pretty well
covered. I might have a closer look at it later today. I also want
to check out any caps that I can find on the main board.

Do you have any way to actually check for voltages coming out of
the power supply?

Thanks Zos, you're pretty much saying what I thought.
I took the power supply out earlier today and had a look to see
if any caps (or anything at all) had suffered obvious failures
but it looked pretty good. Minimal dust, too but I vacuumed it
out, gave things a wiggle and put it all back together with no
change in behaviour.
I'm only annoyed because of the scanner. I'll have to check
whether I've scanned all of my 35mm slides. I scanned the last
of my medium format stuff last year.

It should start up with a bad battery. Your power supply is
most like dead or the caps on the board have failed.

Hi all,
I started up my old G5 to do some slide scanning today but
it seems to be on the blink. At first I had some strange
problems communicating with the scanner but it came right and
I got a couple of scans done.
I left the machine to idle while I had lunch but when I came
back it had frozen up and I had to hold the power button down
to get it to shut down.
Now it won't start up :( The fans and hard drives spin up
but that's it. No chime, no signal to the display. The
power LED only lights when I press the power button. I think
it was lighting up at first, but it stopped after I did the
PMU reset (see below).
I've tried re-seating the video card and the memory, tried
starting it with the hard drives unplugged, and also with a
different monitor connected to the other port on the video
card. I'm not able to get it to respond.
I've tried resetting the PMU / SMU using these instructions,
with no luck. http://support.apple.com/kb/HT1939
http://support.apple.com/kb/HT1436
I also followed the procedure to reset the PRAM but I didn't
hold much hope. http://support.apple.com/kb/HT1379
I'm now at the conclusion that the power supply is probably
faulty. Do any of our resident Mac experts have any further
suggestions? It's a first-gen single-processor 1.6GHz G5.
I just checked and it's just a couple of weeks over 10 years
old!
I've wondered if it would be worth replacing the battery on
the motherboard but I'm not really sure.
I've only kept that machine around because it has no resale
value and Minolta didn't release drivers for later OS
versions because they exited the scanner business. I
couldn't stand Vuescan when I last tried it so I don't really
want to go down that route. I guess the good thing about it
having no resale value is that I can replace it cheaply
through the secondhand market.
Unfortunately I was just getting started on a project to
scan some really old glass-plate slides for someone :( Might
have to resort to a macro lens and a light box.
Cheers, Dave
