1st gen. iMac G5 power supply failure

Hi, all!
My 20" iMac G5 here at work collapsed and died on me about a week ago. The computer just deactivated abruptly; I actually had thought that I had kicked the plug or stepped on the power bar by mistake. I restarted it, and it worked for twenty minutes before dying again. Now it's entirely unresponsive. Having read up on the matter here and in the Mac support pages, I'm quite sure the power supply has failed. I'm in the process of finding out whether the computer is still covered under Apple's Repair Extension Program. (http://www.apple.com/support/imac/repairextensionprogram/ - I know the iMac model is correct, my serial number matches the range, I'm just not sure if the computer is less than three years old.)
Anyway, the important thing for me is the hard drive, not the machine itself. We're entirely Mac-based here at work, so there is no shortage of machines for me to work on (I've already replaced my old machine with a much newer Intel-based iMac), but I would very much like to retrieve my data from my old hard disk. I've downloaded the DIY guide for opening the 20" iMac G5 and removing the hard drive, but I need some advice on the best plan of action. Should I then open another, working G5, remove its hard drive, insert my old hard drive and transfer my files off to my new iMac through our company server? Or is there another way to approach it? Is the hard drive on my 20" first gen G5 compatible with newer mac models, or am I going to run into problems with connectors, physical disk size, etc.? Or, should I just leave well enough alone and leave the entire operation to a Mac Genius?
This will be my first time opening an iMac. I believe that I can open the machines and remove-replace the hard drives without voiding any warranties, correct?
Thanks so much in advance for your help and advice!

I am on the phone right now with a product specialist about my iMac G5 power supply issues. Kind of ***** because he has, in so many words, said that the Genius is the Alpha and Omega and can extend the 3 year coverage. For me that is great except that the Apple store is over an hour away. I don't understand why the dude on the phone can't pull the switch and make it happen as well.
Factor in:
Unplugging iMac G5 and all peripherals
Loading it in the car
Driving an hour
Carrying it into the Mall (apple store)
Waiting for my Genius appointment
More than likely getting it fixed for free (from the sounds of things)
Driving back after it is fixed
Doing everything listed in reverse.
Would it just be easier to pay the $108 for a new power supply, wait a few days, undo some screws, and BAM! it works again?
Update. Off the phone now. The product specialist flexed his muscles, back handed the Genius to gain authority, and basically stated that they WILL DEFINITELY repair either the power supply or the logic board or both if needed. I have already had them replace the logic board once. BUT, I still have to load it up and take it to the Apple Store. Boo.

1st Gen iMac G5 BAd Power Supply

Hi, My iMac G5 power supply is officially dead. It was confirmed at the Apple Store at the Genius Bar. Apple apparently no longer sells the power supply for the first gen iMac G5s. I have two questions: Does anyone have a suggestion on where to buy a 3rd party power supply for that model? I'm not exactly sure what I should be buying. And secondly, is it worth it to do? I know the second question is more opinion but I'm curious of the success rate of replacing the power supply. My preference is obviously to replace it rather than laying out the money for a new iMac which I probably can't do right now) but if anyone's experience is that I'm just throwing money away on the power supply because of future issues or unreliability, I'd like to hear about it.
Thanks as always!

[Synaptech.com] or [welovemacs.com] will not only sell you the correct part, they will give you installation instructions. Another source is [http://www.jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php]
As to your second question, as long as the rest of the Mac is in good shape, replacing the power supply should give you a few more years to collect your pennies for a new one down the road.

1st gen imac,dual core no power? Some helpful advice requested please....

Please pardon my grammar, sentence syntax and perhaps spelling!
Yes I have read all the gloom and doom posts regarding logic boards etc, what are the chances it might be a power supply issue?
Cord in and out, pram reset, no power light, no response to keyboard, no connected accessories, nothing on screen, no response to attempted insertion of disks, so sound (start up or otherwise), no sound of disk trying to boot etc, etc. Tried alternative cord as well...rarely shut down except for moving unit, days away etc
Please could you helpful guys and girls throw some ideas about what my issue with this rather old (first intel imac early 2006, 2o" screen) but beloved piece of tech might be?
My Imac simply went to sleep one fine spring morning and never woke up. Thanks in advance!!

1st gen iMac G5 resurrecting from the dead? (strange clicking sounds)

I have a first gen iMac (pre-iSight) that I bought a few years ago brand new. But the past 8 months or so I've been having a very strange power problem where occasionaly pressing the power button does absolutely nothing... WAIT! I know you hear about this problem all the time but before you click 'back' I'll have you know I too have read countless of these types of power problems on forums, but this one seems different!
Sometimes after unplugging, waiting for a few minutes, then replugging the power supply (while all other cords disconnected) it'll all of the sudden turn on. I recently checked inside the computer as one tutorial suggested to see if the first of 4 LED lights turn on when plugged in, and it does, meaning it's not power supply failure. The biggest problem with the whole thing is that is that the "unplug-then-replug"(sometimes upwards of 15 times) doesn't always work, and always seems to happen at varying degrees of inactivity depending on how long the computer has been off.
I've been doing this for 8 months, afraid to turn my computer off not knowing for sure i'll get it back on (which can take up to a day sometimes). And my resurrection methods seem to be more and more futile, as today and yesterday i've had no luck. LASTLY -- and this really confuses me -- I usually hear a very faint but rapid clicking noise when I plug in the computer (before I even turn it on, never happens when it's actually on) after its been unplugged for a while. The sound seems to be coming from near the bottom of the computer, so I cant imagine that it's that dreaded "Hard-drive Death" symptom (since the hard drive isnt even running).
Please, if you can, offer me some insight regarding these issues, I've looked everywhere and it seems I'm the only one having them! I'm almost to the point of gasp! actually finally going to the apple store and paying them to fix it.....

Hmm, the fan? How would I go about checking that? I want to try everything I can.
DEVELOPMENT: I got the computer on last night (using it right now)! I think it was off for almost exactly 24 hours since the last time I had it running. The most frustrating thing is that I don't really know what I did differently to get it to boot up again. That whole day I was just checking it about every hour or two, unplugging and replugging the power (at one point I opened the back and tried pressing those two tiny buttons under the fan, one is an internal power switch, and the other some sort of reset button, nothing noticeable happened with either, although the clicking sound that occasionally showed up hasn't reared its head lately). I think my computer is almost at its end, and now that its on I'm going to try my best to keep it running. One more slip into a coma and it might not make it out...

Time Capsule power supply failures

Has the chronic Time Capsule power supply failure after about 18 months use been fixed in the new Time Capsules being sold today? I had a 500GB Time Capsule I recently had to scrap because of this.

It is always possible there is another fault.. to shut down after a minute.. if you are relating that correctly.. is unusual.. I would power the board from 5v 2A supply.. that will quickly show if the issue is your power supply or not.
The TC is definitely in need of more cooling but I would hate to suggest doing a major modification until it runs out of warranty. It is possible to improve the existing cooling with a bit of smarts.. a laptop (or netbook size) cooler to which you can seal the TC.. this is the tricky bit.. you need to allow a space underneath though.. perhaps 10mm.. and seal just the edge of the TC so it allows the cooler to draw air through the TC. That will work without modifying it. But you will need to make up a proper spacer and gasket.
I see pictures of various fans mounted on the top.. they are next to useless. Cooling the outside plastic will achieve only the tiniest improvement in heat transfer due to the thick plastic (insulating) top.. if it was made out of metal maybe it would do something.
Sounds like what is also needed is a different heat sensor that would start the fan at a lower temperature.
It is not the sensor that is the issue. The TC includes a proper fan controller. It is simply set too high.. and so it doesn't turn on.
If you want to break into the TC.. you can solder in a console.. and use serial to USB adapter.. these are very cheap.. the soldering in is tricky.
See the bottom of this page.

The envstat.. will show temp.
This command will turn on the fan.

Troubleshooting power supply failures

I'm branching out this thread as a continuation of <http://discussions.apple.com/thread.jspa?threadID=2418851> since the topic has evolved and the subject is no longer accurate.
I have a 2.1GHz iMac G5 (iSight) that does not boot reliably and sometimes goes into deep sleep and can't be awakened. I have ruled out software and RAM issues, leaving power supply and logic board as the likely suspects. I'm leaning towards the power supply. I'd like more info on the symptoms of power supply failures and see if my symptoms are consistent with it.
*Reasons to believe it's the power supply:*
• symptoms are consistent with the computer not getting enough power.
• it's a more common failure.
• Computer has 4+ years of continuous usage.
• the left side of the vent had been warm lately (that fan pushes air over the HD then the PSU)
*Reasons to believe it's the power supply:*
• visual inspection showed no damaged capacitors (although there could be hidden damage)
• in my previous experience with power failures, the Mac shut down completely, not half way.
*Reasons to believe it's the logic board:*
• problem triggered by adding RAM (although that's not the only trigger and removing the RAM didn't • instantly solve the issue. Timing may have been a coincidence)
*Reasons to believe it's not the logic board:*
• It passed all the Apple hardware and Techtool Pro tests.

FYI, you can access them in /private/var/logs, but you need to use a utility to show invisible files first.
The last system.log entry is

I received a 1st Gen IPad from a supplier as a gift to promote their products. They used their Apple account to load the apps. I am not able to load my own apps because their apple user is the one that pops up. How can I change it to mine?

No video whatsover G5 1st gen iMac

My friend got this pristeen 1st gen iMac for free at a 2nd hand store outreach center. The HD and ram were missing and a I T tech we thought knew told us that was all it needed. I had no experience with anything Mac but I'm willing to learn. After installing 2 Gb of new PC 3200 400 mhz ram,new Western Digital 320 Gb 7200 rpm 32mb cache Sata hard drive, new apple wired keyboard,new Turtle USB Mac mouse and the brand new OS X Leopard disc and..... no video! I'm thinking this needs a replacement mobo but the mobo and capacitors are all looking great(appears new) so I don't think they're the problem. If I'm missing anything obvious please help. Possibly there's a video card missing and I don't realize it yet. Otherwise I'll be looking for one of those replacement G5 mobo's or a trade plus difference deal for another refurb or used Mac. Any ideas?

Is it starting up, but with no video? Or is it not starting up? I'm not certain an iMacG5 will handle a SATA disk drive successfully. Another possibility is that whoever had it before saw it die, salvaged the HD and RAM, and junked it. Sometimes you get what you pay for! You could get an external case for a SATA Hard disk, and maybe find someplace that would take the RAM in trade for some that's right for a new Mac, and be ahead to just buy a new one. If you're like me, I HATE to see one bite the dust with no hope of resuscitation!

Choppy video playback on my 1st Gen iMac G5

Everything from internet video to DVD playback on my 1st Gen iMac G5 is choppy and getting more so as time goes on. Can anyone tell me if this is a symptom of the defect that's covered under the extension plan or is this just some other problem?

Check the version in the Application Folder!
(I have had no problems at all after installing QT 7.5 on my G5 iMac in case you think it can't work at all.)
It is possible that something in either your pre-existing setup or your method of installing updates, are the root causes of whatever problems you are having with QT 7.5 particularly with choppy playback. Out of date plug-ins and add-ons could also be playing a part. Some users have found choppy playback to be associated with improperly loaded plug-ins and add-ons from third party vendors as well as those included by Apple with prior versions of Quicktime.
Third-party add-ons include DivX, Flip4Mac, or FLV components, while the included plug-ins are AppleIntermediateCodec.component, and AppleMPEG2Codec.component. The files for these are located in the root library, therefore a faulty component will load improperly for all users, resulting in choppy playback even when a user creates a new account. Some may need updating or just reinstalling to work with QT 7.5.
You should therefore:
Remove and re-add all quicktime components and plug-ins.
Navigate to /Library/QuickTime/
Move all plug-in ".component" files from the folder (to the Desktop, for instance)
Launch QuickTime and quit it again
Place the ".component" files back in the QuickTime library folder
Launch QuickTime again, and the choppiness should be better.
A few more things to try but in each case first close all applications and repair permissions.
1 Try opening then closing GarageBand, or launching then quitting the "Audio MIDI Setup" application located in Applications/Utilities. Failing that, go back to Audio MIDI Setup, and under the Audio Devices tab, make sure the Audio Output Format is 44100.0 2ch-16bit.
Restart your Mac.
2 Go to the Library on your main hard disk and find the Internet Plug-Ins folder. Try removing the following files:
QuickTime plugin.plugin
Quicktime plugin.webplugin
Restart your Mac.
Re-install the Quicktime 7.5 update
Go to Home/Library/Receipts and delete the file Quicktime 7.5 pkg.
Download from the Download page on the Apple site the correct version of Quicktime 7.5 for your Mac.
Install it and restart your Mac. Repair permissions.
3 If still no luck, it is time to look carefully at your plug-ins and add-ons. The safest way is to download and re-install all of them. The ones you need in order to see and hear virtually everything the web has to offer are:
RealPlayer 11 (which is no longer in beta) for Mac from:
http://www.versiontracker.com/dyn/moreinfo/macosx/15540
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.)
You should also ensure that you have downloaded and installed all the correct version for your Mac of all recent Security Updates.
(N.B. Security Updates require both a restart and a permission repair.)
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
There is an additional 'fix' you could try if you are having problems with Flash and Quicktime, depending on which type of Mac you have:
On Intel Macs, make sure that you are not running Safari in Rosetta. You can check this, and change it, in the Get Info window.
On PPC Macs, go to the Hard Disk/Library/Internet Plug-Ins folder, and drag the file 'QuickTime Plugin.webplugin' to the desktop. Quit and restart Safari. If things have improved you can trash that file. If they haven't put it back, as the lack of this plug-in can cause QT content in some widgets to cease functioning.
If none of the foregoing worked, then you should consider and archive and install before repeating all of the above.

1st gen imac g5 graphics problems

Hi-
I have a first gen 1.8ghz 20" imac g5. About a year and a half ago, the mother board was replaced because of the exploding resistors. Recently, the screen has started intermittently getting pixelly in spots (like it did pre-mo-bo replacement) and then freezing (which is new). It happens every day or two, or sometimes within 10 minutes of booting. It seems to happen more quickly when Safari is up strangely enough...
I took it to the apple store this weekend and the genius there said that the resistors were not exploding and that the mother board looked good. I haven't seen any drivers for the graphics card available. Wondering if anyone else has had this experience and if there is anything that can be done. A shame to have to do away with this thing...

HI,
I too have a 1st gen iMac G5 20". It too recently started showing artifacts on the screen. For example when moving a window parts of the screen would get messed up. The problem became worse to the point where it would get stuck on a blue screen during boot (mouse and pointer still working). I took the cover off and saw three leaking capacitors on the mother board. They were in the group of 5 near the middle bottom of the board. I had them replaced, but unfortunately, this did not fix the problem or improve it in anyway. At the moment I have no idea what the problem is. Is this in anyway similar to your problem?

1st Gen Imac G5 Question

I own a 1st Gen Imac G5. I just recently purchased the Apple VGA Display Adapter hoping I would be able to use an external monitor as an extention of my desktop... after looking through the system preferences I realized there was no such option. I thought it might have had something to do with the OS version I was using so I upgraded to Leopord thinking it would solve my problem... it did not. Is there any sort of Patch or possible solution that could solve my problem?

IMacs G3 power supply compatiblity question

I have an original Bondi blue iMac G3. Power supply works OK.
I have a flower power iMac G3 but the power supply is defunct.
Can I swop the Bondi 's iMac power supply to the flower power iMac?
Thanks.

Unfortunately the answer is no. I just checked Mactracker & the Bondi Blue iMac uses a 80 watt power supply. The Flower Power iMac uses a 150 watt power supply. So if you tried to use the Bondi Blue iMac's power supply it probably wouldn't provide enough wattage for the iMac to work properly. I would recommend looking on eBay for a replacement power supply. Some vendors might have one or more in stock.

Help - nonworking 1st Gen iMac 20" with bulging caps (power supply)?

I have a 1st Generation (Rev. A) iMac G5 that does not power on. I looked at the logic board, and all of the capcitators appear OK. None are bulging. Most have a "K" on them, some have the infamous "X."
I took my iMac into the Apple Store Genius expecting to be covered under one of the iMac G5 extended repair programs for out of warranty iMac G5s:
http://www.apple.com/support/imac/powersupply/repairextension/
http://www.apple.com/support/imac/repairextensionprogram/
I did not qualify for either, as the one is only for video AND power issues, and the other only for Rev. B iMacs.
So I took my iMac home looking to buy a power supply. I took the power supply out and opened it up and found all "X" capacitors, some of them bulging.
So what is my next step?
• Should I phone Apple Customer Relations at 800-767-2775 or Executive Relations 800-275-2237?
• Should I take the power supply back in and show this to the Apple Genius and explain my situation?
• What about the logic board? Should I demand Apple replace that too, since it has the X caps?
I am out of warranty and no AppleCare. But according to other threads, like this one, this is a known issue and Apple should replace both my logic board and my power supply. But the genius I dealt with this morning seemed very knowledgeable and said he has been working on Macs for 20 years. He actually checked in my Macbook with a couple of issues and is resolving them no problem. But no joy on fixing the iMac.

I took my Macbook in yesterday for video flicker and misbehaving battery. Received new battery, logic board, and inverter cable in about 32 hours. Kudos to Apple for fixing my in-warranty machine so quickly and not blinking an eye. The Genius who checked in my MacBook asked if I read about these repairs on the web, as he said it is a major problem. Ironically, since then I have been cautioned twice by Apple about what I read on the web.
What does that have to do with my iMac saga? Absolutely nothing, other than since I went to pick up the MacBook, I took the iMac back in. Plus, I am trying to find some words of praise with Apple's prompt, no-hassle repair as with this iMac issue I can find no words of praise.
I started out with this new Genius tonight by explaining I brought in the iMac yesterday and the Genius didn't even open my iMac but just checked the serial number and EMC number and must have been confused on the programs. I told him he denied me either program and said the one issue was for Video AND Power issues, and since I did not have a video issue, I was denied. I was asked who helped me, and gave his name, and I could tell the genius in front of me regarded him highly.
Anyway, they brought out the MacBook, I signed for it, put it back in my laptop bag. Attention turned back to the iMac, and I could just sense a reluctance to help me. I had mentioned that there were X capacitors on the logic board, but that none of them were bulging, and I had read that could be a problem in the future and that people were getting logic boards replaced even though the problem was with their power supply and the logic board appeared fine. I received the party line again about misinformation on the internet and not believing everything I read. At least I convinced this guy to open up my iMac, which he would not do in front of me but took it into a back room.
He came back out and said my capacitors were fine and there was nothing he could do. (Well, I had already told him they were fine.) I said that this was for power issues and the problem is obviously with my power supply and he said he could not help me with that.
I was/am very ticked off and just didn't feel like getting into it. Normally I would have asked for the manager. The genius wouldn't even look me in the eye. I feel like I have leprosy or something. Has anyone else with a Rev. A iMac with serial numbers for this program get denied? I have not read such a thing on this forum. Someone please post a link to comfort me so I know I am not the only one.
I just left, in defeat. I've got enough Mac service centers around me that I am going to take it to one of them. In fact, I DID take it to one of them first on Monday morning, but didn't have the original receipt with me, so they said that could be an issue, so I just left and took it to the Apple Store since I was already out that way.
Maybe tomorrow I will find comfort back in the arms of one of those hybrid computer stores. The saga continues...

1st Gen iMac Power Supply Issue

I just got my iMac G5 back from Apple after having the power supply and logic board replaced for the second time in two years.
It is apparently a fairly common problem with the first generation iMac G5s. I've basically been told it's a problem with no real solution and that they'll fix it for free (for the first three years). It's great that I'm within the three years, but if it happens again after October, I'm likely going to have to foot the bill to get it repaired.
Does anyone have any more detailed info on this issue (other than Apple's Repair Extension doc)? Would turning off the computer each night prolong the life of those parts? Would turning it on/off everyday reduce the life of those parts?
Any thoughts/comments?
Thnx...CN

Just to add to BB's comments, I doubt that leaving the computer on will have any benefit at all for you in terms of longevity. If you have problems with faulty capacitors , and the like, in fact it will probably make the issue worse rather than better (though I doubt this will be a problem for you if your logic board was replaced after about April 2005). Doing so will probably also add a little extra wear to the bearings of your HD (unless you have it set to spin down when not needed) , and will cost you a little more (but not a whole lot - though when we all leave them running the environmental costs continue to mount) in electricity over time.
You should probably also shut down every so often anyway - maybe once a week or so, to help clear some potential memory issues that can persist with some applications even under OSX, and you should certainly shut down at and start up again at any time when you notice slowdowns, program "hangs" or other problems.

1st Gen iMac G5 - no power warranty ?

I have a first generation iMac G5, and my serial number falls into the ranges cover by the iMac G5 Repair Extension Program for Video and Power Issues.
My issue is that I've already had my global logic board replaced under this warranty, and now my iMac is not functioning again. I've already tried the SMU reset button, and I also followed the directions found in the help article "iMac G5: Troubleshooting when your computer won't turn on", and my out come was:12. Press the internal power button to start up the computer. Does LED 2 come on momentarily, or not at all?* Momentarily: The logic board has detected power, but the power supply cannot maintain it. Your power supply needs to be replaced. If you have an iMac G5 (Ambient Light Sensor) computer, you can order a replacement power supply here and then install it yourself. If you have any other iMac G5 computer, contact your local Apple Retail Store or Apple Authorized Service Provider for service.
* Not at all: Your logic board needs to be replaced. Please contact your local Apple Retail Store or Apple Authorized Service Provider for service.
I suppose my primary concern is if my iMac is still covered, or am I going to have to pay for this repair? The iMac is only 2 years from purchase date, so it does still fall under warranty time-wise. I'm more worried about the previous board replacement voiding my eligibility.

Per Apple Extention Repair program:
"the repair will be covered by Apple for up to three years from the original date of purchase even if your iMac G5 is out of warranty."
