iMac G5/Intel Power Supply

My Problem

The power supply died.

My Fix

The guide was spot on. There are a lot of fiddly bits with adhesive that are a pain, but can be dealt with.

The new supply dropped right in and works great. My old iMac is still running just fine.

My Advice

I had a couple of very strong magnets. They make getting the bezel off a very easy process. Much easier to do than with a credit card.

My Problem

The IMac G5 would no longer turn on after being handed down to my two adult children.

My Fix

I first got the idea of trying to fix it rather than throw it away from your YouTube video. I then went to the IFixIt web site and saw the tutorial on how to replace the power supply. Having never attempted any computer repair before, I thought if I can get the old power supply out, I will order the new one. All went very well following the short cut method. The pictures were great. The new power supply came very quickly, I put the new power supply in and crossed my fingers. Great news it worked just fine. I could never have done anything like this without your site. Thanks a million.

My Advice

Go ahead and try it. If I can do something like this anyone can by watching the tutorials.

My Problem

When I am away from home for an extended period I usually power off my iMac and disconnect the power. After returning home from a long weekend recently I reconnected the power and nothing, no light no sound, no smell. After multiple attempts trying different power sources and power cords I was satisfied that the machine wasn't going to restart. I opened the case and noticed that on the main board LED1 was illuminated , LED2 would flicker every few seconds and the fans would start spinning then stop. After reviewing similar problems in the answers forum I concluded that the symptoms were consistent with a malfunctioning power supply.After consulting the power supply replacement guide for my iMac replacing the power supply seemed like a reasonable idea and I ordered a new power supply from IFIXIT.

My Fix

The first unit arrived on time. I installed it and there was nothing. The main board LEDs did not illuminate at all. I advised IFIXIT through customer support and the next day received an email informing me that a new unit was on the way with a return shipping label for the nonfunctioning one I had received. When the replacement arrived I installed it and had the machine up and running in less than an hour. I used the Short cut method and this worked well.

My Advice

I only recently found IFIXIT and it has been the most helpful and informative community for mac problems. Thanks to all who freely share their knowledge and experience. This is a great resource.

My Problem

The computer is ten years old and still has a bright screen and I recently upgraded the memory to the maximum available. In other words, other than being a bit slow it was in perfect working order and was the computer used in the shop so I needed to replace it or fix it. I gambled and won...for $150 I have a new G5! That is better than $1000 for a new one.

My Fix

The instructions were perfect. They described the pertinent necessary steps exactly! It took a couple hours since this was the 'difficult' G5

My Advice

Fix you Mac! They will run forever.

My Problem

My PSU in my 2006 iMac g5 burnt out 3 years ago while I was plugging it in. There was a tiny spark and the thing wouldn't turn on. It was too old to get it repaired by Apple.

My Fix

It took about an hour to get disassembled. Once I did that, I promptly realized there was manufacturer error and had to call and get a new PSU sent out. They were very helpful on the phone and the service way exceptional. Shipping took like 2 seconds. Not literally but it was really fast.

While I was disassembling I was at the part where you disconnect the SATA cable. Apparently it's really easy to rip right off the board and then you are out of luck forever since it has to be soldered back on meticulously. The internet and my local Mac repair shop said it's not worth it to even try to fix.

Putting the PSU in was easy and putting it back together took probably 30 minutes. It powered right up beautifully. Of course it can't read the hard drive so after that it just blinks a flashing folder icon with a question mark in it.

Only after all that did I see there was a guide to replace the PSU without taking the whole thing apart. HAHA OOPS.

Conclusion, I fixed the PSU successfully. The guide was really good, the part worked great and then I broke my iMac forever in a different way. The End.

My Advice

Don't break your iMac while you're fixing it.

Try to do the shortcut of replacing the PSU first.

If you feel you must take the whole thing apart, be VERY VERY VERY VERY VERY VERY careful with the SATA cable disconnection. It was EXTREMELY hard for me to unplug even with a spludger and instructions so I thought maybe I'd give it a little tug since the other cables seemed to need a little force to disconnect. That's where I went wrong and it just ripped away from the board completely.

Also, if you DO break your SATA cable off you can run your iMac off an external drive.

My Problem

Guasto del trasformatore.

L'assistenza ufficiale Apple non fornisce più il pezzo di ricambio.

L'iMac per loro era spacciato.

My Fix

Bene, ho seguito passo passo la procedura guidata e sono riuscito a sostituire il trasformatore.... il Mac non è esploso.

My Advice

Io non avevo mai fatto un'operazione come sostituire un trasformatore, ma grazie allo staff di iFixit è stato un gioco da ragazzi.

My Problem

2 coupures de courant et mon bon vieux imac ne démarre plus. Encéphalogramme plat. SAV Apple : on ne répare plus; il faut le remplacer 1299 €. Cher pour une alimentation!!!! et puis M6 dimanche soir sur capital et 5 jours après imac ressuscité (alimentation commandé sur ifixit).

My Fix

Sur des roulettes. y a qu'à suivre les instructions.

My Advice

Difficile de décoller le scotch. Je l'ai remplacé par du scotch en aluminium type conduits d'aération...

My Problem

The computer was not booting. It would spin up the CD and make a few disk noises, but nothing else. After closer inspection and gaining familiarity with the hardware (more on this later), I noticed that only the first 2 debug LEDs (middle of logic board) were lighting up and the white "status" LED in the right speaker was constantly lit.

My Fix

Being inexperienced with the machine, I took the advice that the power supply needed to be replaced, ordered the part, and made it through all 45 or so steps without an issue. When I booted up the machine again, nothing had changed, which was bad and good (at least I didn't break anything). After some more reading and exploring iFixit solutions, I realized that corrupted memory might have been holding up the whole boot process. I ejected both sticks and tried one at a time. I got it right on my second try and rejoiced!

My Advice

Make sure that the power supply is the problem. I should have spent some more time looking at the computer before taking external advice. Lights being on, etc, are clues that the power supply is okay, and there's something else holding the boot up. And get a magnetic T10 torx screwdriver for the screws that anchor the display (or be forced to use sticky tack in the reassembly like I did)
