It is clearly laid out in your computer documentation, but go here... I could restate the facts, but just read the thing for yourself,
BTW, it is the hardest and potentially most destructive thing you can do yourself, replacing the PSU.... good luck...

You might be able to find diagrams on Personally I wouldn't risk it if you don't know how to possibly soder stuff to the logic board. The G5 and Intel based Mac don't have the nice zif type processors of the G3/G4 days.

IMac 24 core2duo 2.8 (A1225) early 2008. Got one without HDD. I put in a new 2.5 HDD and tried to fresh install OSX 10.8. Everytime after about 8 minutes in installation process the screen goes black and...

Now what did the Thermal Paste have to do with the swapping in a new Hdd. You've now added another variable to the equation before solving the first problem, getting it up and running. Grab another Mac and put the iMac in Target Disc mode, firewire the two, use the USB drive with 10.8 and install it on the iMac and see how that goes.

What prcoessor do I need for an iMac? Will any 2.93GHz Quad Core i7 fit or are they mac specific ones? I currently have a 3.2 core i3 and I'm looking to upgrade.

Hi Jake,
Unfortunately, Apple has made upgrading CPUs impossible in basically all their products. You are stuck with what you originally purchased. Only way to upgrade a Mac's CPU is to sell you current iMac and Buy a NEW one..

Luckily, iMacs have an excellent resell value, the whole process might actually be less expensive than than a CPU upgrade would cost.

2 red lights on logic board

I don't see that in the service manual. You should give some symptoms and details about the power on LED, fans PSU etc. You need to verify the PSU is good before you get to the logic board.

Apple hard test error 4sns/1/40000000:tp0p-131.000

This error code is from the PSU sensor. Verify that the single pin connector on the top edge of the power supply is present and securely plugged in. If damaged replace the DC PSU cable. Causes the CPU fan to run at full speed.

I have an iMac 17

Thanks for contacting FixYa Support.

I have repaired numerous iMac G5 17" models for a while now and because I have, I can tell you just from the symptoms you have described, this is potentially a power supply issue.

However, the iMac G5 17" have been known to have swollen capacitors, which can also ultimately impact the power management / performance of your iMac.

If you are able to, very carefully and don't touch them, you can look on the iMac's main logic board to see if you notice any swollen capacitors. If you are not sure what a capacitor looks like, they look like mini batteries connected to the board.

Should you do this and find that the capacitors are ok, then I would recommend for sure, that you look into replacing the power supply.

For your model of iMac 17" provided it is not an Intel-based iMac, the part number you will need to source is part# 661-3627. Below, I have also provided the most inexpensive price for this iMac power supply per this link:

You may find even lower prices for this iMac 17" power supply, if you search online further, but this is one of the better online Apple components vendors. Therefore you should be able to see and compare the prices on this website, with some of the other vendors
advertising the same Apple power supply for the iMac 17".

I hope this helps. If you have any more questions on this subject, simply reply back to this post.

Best Regards,

PM G5 has red light at front before switching on

It could be your motherboard but I would first try a Apple hardware disk and run the diagnostic tests.  If you can't boot from the DVD you could try a PRAM reset.  I have seen other weird issues with the hard drive not mounting which causes the fans to run loud.  The Apple Diagnostic disk comes in your original software pack and its usually on the 2nd or 3 DVD.  Sometimes the CPU speeds get out of whack and they need to be recalbrated.

You can try to boot from your recovery install media, by pressing the option key instead of the c key. Then choose hardware diagnostic, followed by selecting the arrow button. This test will be able to tell you if you have a problem.
