Yes

Symptoms

Fans were found on full blast during sleep. Mac wouldn’t wake. No entry symbol on next startup. Ran AHT & utilities managed to restart, but fans sounded a little louder. Noticed it was running on only one CPU.
Ran more tests, removed RAM and other addons, did PSU & PRAM resets etc.
When starting after being left both the CPUs would work before crashing back to one.

I found a manual on the net & took it apart to clean & reassamble. It worked for a few days then the same thing happened.

Diagnosis

Local Apple Genius bar said ‘It could be the CPUs or main Logic board failure’. I can’t afford the possibility of replacing all those parts.

Symptoms

Suddenly failed - failure to start up, freezing on grey start-up screen, turbo fans, random freezes when in use, kernal panics. Machine unusable.

Diagnosis

Apple Geniuses diagnose either faulty logic board or processors - Applecare expired 4 months previous - quote between £500 and £850 to repair which I will not be proceeding with - Machine now useless.

No

Symptoms

After a Leopard upgrade, the machine was balky and finally displayed a grey screen together with overspeeding fans.

The techs at my local Apple stoere ran a hardware diagnostics test and then replaced the primary hard drive. The machine still wouldn’t boot up.

They then surmised the problem as a logic board failure and recommended replacement of the logic board and processors and power supply, to the tune of “at least” US$1,500.

Diagnosis

Repair history

This machine was bought new from Apple and has been in one room for its entire career as a lightly- and infrequently-used FCP editing station, always with a large external fan blowing into it.

Both its failure, and Apple’s inability to trace the fault to a particular component or specific spot on the logic board, leaves me with major questions about their machines’ usefulness as professional tools.

My intention is to seek compensation through the court system, using both a defective design legal theory and a deceptive trade practices legal avenue.

No

Symptoms

the first symptom was that the machine would freeze on wake up…This happened for a couple of weeks…. I ran the usual fixes ie reset pram and fixed permissions…
Then I left it powered down and unplugged for 3 weeks while I was overseas…
On powering up it failed to boot… I then tried several different ways to get the machine to reboot ,like resetting the Pram on bootup and booting the hard drive on another machine in target mode.. the hard drive seemed fine and the G5 would boot up some times but then it just failed altogether :(

Diagnosis

I took it along to the Apple tech service centre where they ran all sorts of tests ( I have full documentation) to much to go into here I could post it as a file if any one is interested…. The up shot was that the service tech reformatted the HD.. reseated the CPU’s…re calibrated the thermal processors.. Did a clean install and ran a stress test for more than 12 hours…. The machine still failed… so he removed the HD and booted from an external firewire HD… this got the machine working… Sort of…
As it stands at the moment I can only boot from the firewire Drive and it wont sleep
also the monitor keeps flashing… the Tech suggested I buy a new Logic Board but offered no Guarantee that it would fix the machine… all it is good for now is getting my emails….. :[ ps it wont run any pro software with out freezing…

No

Symptoms

Hidding the start button will only start the fan. Mostly you can hear some kind of a klick inside the sytem. After this nothing else happens: no chime, no HD-action, no video signal… Nothing. And as soon as the button is released the LED turns off.

Diagnosis

AASP said the logic board has to be changed. It’s definitely not the power supply. They tried a new one and it wan’t help.

Repair history

Problems while booting happens for the first time more or less immediately after I bought the machine this summer. At this time I was experimenting with various HD’s and displays, so I thought that this caused the problem. In the beginning the computer booted after a few tries. But it became more and more. After a period of relativ stability the Mac seems to went dead in September. I brought it to a free workshop and they give it back to me still running, claiming that it was a unique firmware problem. But at the end of November the symptom reoccours. The workshop couldn’t help it so I contacted a local AASP, that made the sad diagnosis.

Miscellaneous info

The machine is from June 2004 - so the trouble begun shortly after the G5 became 4 years old.

No

Symptoms

I thought the fans were louder a couple of months ago so I installed istatpro and checked the numbers with what some other people had posted on message boards and it seemed to be normal. I hit the power button and walked away one night and when I came back the fans were running and the status light was on but that was it. I turned it off at the power strip, turned it back on and reset the PRAM and it booted but after five minutes it froze. I turned it back off again and after that all it would do is turn on the fans and blink three times.

Diagnosis

I didn’t take it to the Apple store because I’ve always done business with a local reseller. They said it wouldn’t work no matter what RAM they put in so they recommended a new logic board ($860 including labor), which I agreed to because it was cheaper than a new computer. I asked repeatedly for details about what specifically had gone wrong but they had no clue.

Repair history

I’d never had a problem of any sort before this. To the best of my knowledge I’d never even moved my Mac a millimeter since I first got it.

When Computer warm, have tried restarting in Single User Mode after a freeze - Still no joy - freezes before it gets to the Prompt
Reset PRAM.
Reset CUDA.
New Internal Battery installed.
Reset Open Firmware
Swapped out Graphics card with a working G5 machine. My machine still freezes.
Replaced Hard Drive with new Western Digital Drive and installed OS10.4 +Combo Updater. System worked for about an hour then froze. Repeated Process with Seagate Barracuda Drive. Same thing happened.
Run Hardware Monitor, and note that temperature of both CPU’s will suddenly spike from 42 degrees (temp after 15 mins running) to 55 C and cooling fan will switch on for approx 5 secs. Temperature reading is ‘spiking’ and resulting fan activity can be bought about very easily by rapidly resizing the 1 open window in Hardware Monitor.

No

Symptoms

Froze completely during normal operation. Fans went on high, would not respond to keyboard. Had to shutdown using the main power button. Would not reboot. If restarted, then froze on grey screen, fans on high. Got kernel message once. Would not reboot without freezing.

Diagnosis

I replaced the logic board battery, froze again. Reset the PRAM, froze again. I have tried reseating the RAM, taking out the HDs and reseating them, ditto on the video card. I have been able to backup info from the HDs, but the CPU would freeze after 5 minutes and I had to do a hard shutdown. Tried off and on for a week to get it to restart to attempt to back up data. Read all threads on this issue online and finally took CPU to Apple Store on 11.26.08. Genius diagnosed a video issue, ordered a new card.

Repair history

This machine was bought new in 2005 and has never traveled or left the room it was set up in. It has never had any repairs or issues. Two days after I left it at the Apple Store, the new card hadn’t come in so I picked up the CPU & installed a new card at home, didn’t work. Just froze again. All that’s left to try is a new (used) logic board, but they are hard to find and there’s no telling what shape they’re in. I am severely disappointed in the premature death of my G5.

Symptoms

Same as others.

Leopard update caused Grey screen and fan over-cranked.
Would not boot.

Applecare avoided all assistance.

Diagnosis

I suspect Apple does not want to support any pre-intel machines. Particularly large expensive ones. Leopard clearly started the problem and I believe recent update created the catastrophic breakdowns.

Our Mac consultant called it: Logic board/Processor failure.

Repair history

Prior to this none had been required.

This issue was red-flagged at Applecare.

Symptoms

Encoding video, I left the room for maybe 20mins tops.
Came back to a kernel panic(system failure) “corrupt stack on CPU-1” with fans running full throttle.
Then it refused to boot giving me a black screen, then a gray screen on subsequent attempts.
Then the no entry symbol and kicking the fans on high again.
Swapping the physical locations of the CPU’s and removing PROM battery allowed the system to boot with 1 CPU, fans still running high.

After a few weeks the system just stopped powering on altogether.
Only way to boot it is to apply heat to the lower left corner of the logic board, and then it freezes up unless I disable 1 of the CPU’s using the CHUD tools preference pane.

Diagnosis

Failed logic board.
By process of elimination.

Repair history

Had the LCD module in the cinema display replaced about 1.5 years ago.
Had the suprdrive replaced about a year ago.
Those repairs were done when the applecare plan was still active.
My applecare plan expired about 4-6 months before this problem occured.

Came home after walking the doggy. Heard the fans reving at full throttle. Saw gray kernel panic screen. I (in turn) panicked and did a hard shut down. Rebooted and same thing happned again after a few hours. While installing the 10.5.7 update (thinking it would fix the kernel panic’s) the computer froze again and hasn’t been running on 10.5 since. I successfully installed 10.4 on a free partition on my system drive and I can boot up with 10.4, but practically nothing works withouth freezing the system. I have no sound and the video screen is choppy sometimes… I don’t get gray screens anymore either - the computer just freezes.

I have tried the basics. Reinstalling OS, reinstalling RAM, removing USB/FW devices, tried different HD’s with different OS installations - etcetera ad nauseum - to no avail.

The power button LED flashes and computer fails to boot up.

Diagnosis

I’ve checked many forums and mac help websites, (one mac helper has been using macs since 1985) He told me to check the ram so i did i took out 2 of the ram sticks and then tried to boot, the chime sounded and it booted the Mac I moved my mouse alittle and then everything froze again. I turned it back off and then on and it would not boot up again. Then i was told to zap the PRAM. After resetting the PRAM still no change on how it booted up. I replaced the mother board battery and still it wont boot up.

Symptoms

Locked up and Fans went full speed. Diagnosed by Apple as failed logic board. Logic board replaced by Apple at no charge. Capacitors were WAY bulged out - I could see.

SECOND FAILURE, on July 20, 2009.

Prior to July 2009 failure - I endured a year or more of partial failure - it would lock up and fans would go full speed ONLY if I let it go to sleep. I never let it sleep since.

July 2009 - Just spent extensive time setting up leopard on the HD, then went to bed letting updates off the web install.. Morning and the machine was off. I managed to start it after some effort and then after the next shut down - that was it.

Diagnosis

Apple diagnosed a power supply bad but noticed the SLIGHTLY bulging capacitors (group of 5 or 6).

I got a second opinion at after market tech shop.

We put in a different power supply and the board still failed. #1 LED comes on but that is all. That LED is flickering also.

Repair history

Board had been replaced by Apple a couple years ago - outside 1 year and no Applecare, but under special warranty/recall…

Miscellaneous info

AS stated above - after new board was put in. it soon went full tilt on fans and locked up if allowed to sleep. Miserable failure of a repair solution. Took it to Apple for that and they blamed software or “I dunno.”

It died, I took it to repair center, they diagnosed a bad power supply. Paid for that since it was 2 months out of warranty, and then 1 month after picking it up from the repair center it died again. This time they said logic board, to the tune of $1100 to repair, and a new comparable machine was also $1100.

Repair history

Never used the Applecare. I paid out of pocket for the power supply, and when the logic board crashed a month after that I decided not to throw good money after bad anymore.

Diagnosis

I self-diagnosed a bad power supply, but the same symptoms occurred with the new replacement. After reading several forums, I’m convinced that it’s either failing processors or components of the mother board.

Symptoms

After 5 years of complete and total perfect operation, kernel panics began on August 4 for the first time. Computer would operate after restart for about an hour, then kernel panic again. After that, the computer stopped booting up. Eventually the computer would boot after 5-6 tries only to crash 5-10 seconds afterward. AHT tests pointed to Video card and mass storage failure. Took G5 to Apple for compete diagnosis, and they replaced the video card and said that was the only problem. Got home and powered up the computer only to get kernel panics instantly.

Am going back to Apple to discuss the stealing of $500 from me and the fact their diagnosis was worng and my computer is still a door stop. Computer as of now freezes on the apple logo screen on boot up and won’t turn on.

Fans started running haywire at beginning of the demise. Problem seems to be heat related, but that is just a guess.

Diagnosis

After supposedly running extensive tests, Apple diagnosed the problem initially to be video card. It was replaced for $500 (including diagnosis fee), and upon returning home and powering up the computer, kernel panic instantly.

Going back to Apple today for discussion about what they did to diagnose the computer initially, and what they are going to do to find out what is wrong.

Repair history

New NVIDIA 6800 Ultra video card installed by apple last week. Did not solve problem.

No other problems with computer in 5 years of using as a audio mastering tool in my studio.

Miscellaneous info

Tried loading 10.3 and 10.4 on fresh installs on both hard drives and still had kernel panics upon boot up. Tried swapping monitors, and that did not work. Won’t boot at all now. Fans seem to run sporadically.

Symptoms

Sudden death. Froze up that day and never ran for more than an hour after that. I can run in target disc mode all day and it has become a real expensive external drive.
I bought a MacBook Pro and use a G4 and 2 G3 iMacs (the iMacs were used in a school for many years before I salvaged them) I still have my IIe purchased in 1982 and it still works. I know that Apple will do the right thing for the loyal customers that have supported them all these years. Everyone ready? Bend over!

Diagnosis

Faulty logic board. The problem is caused by thermal expansion and contraction and can be fixed at the board level by a skilled technician with solder. Providing the broken trace can be found. I can make it work by pressing on the logic board in a certain spot. If I ease up on the pressure it freezes and needs a restart and the finger to run again. Well I need my finger for other more important things such as saluting those at Apple that continue to ignore the G5 owners and this growing issue.

Fails to boot at start up, power button indicator flashing 3 times.

Diagnosis

Suspected faulty RAM / logic board.

Repair history

Taken to registered Apple service centre who cleaned points and reseated RAM and got it to boot up. Failed to boot up first time when brought back to my office, but did the second time and ran smoothly for a day. Second day failed to boot again, checked and reseated RAM without joy, took back to repair tech who got it back to life and tested it powering up and down all day. Failed to boot when back at office, repair tech suggests a faulty logic board with loose connections.
Previous repairs include replacing hard disc; disc drive (due to dust during renovations) and addition of more RAM (over 12 months ago)

Symptoms

Last week My mac froze. It froze the way the OS9 would (everything stops). I rebooted many times with a variety of results. The grey multiligual screen of death, blank screen, hanging at the apple logo, code all over the desktop, etc. Sometimes with a chime sometimes with no chime. I tried reseating ram, videocard, swapping drives, restting the pmu, all to no avail. I left it alone for a day or so and came back to find it booted and stayed that way for 30 minutes. Then the whole parade started over. I managed to get it back for a day, did as much work as I could but noticed that I had lost about 1.5 gigs of ram. So I rebooted yet again. No joy. the ram was gone and once it went to sleep it never woke up. It sits there like that now. Anytime I try to reboot, I get 3 flashes on the power button teling me I have bad ram slots.

Diagnosis

TBD. Going to genius bar but suspect the worst.

Symptoms

My power mac G5 dual just turns on and only shows the grey apple with no turning candy ball and it wont boot up.

Diagnosis

Northbridge(U3) is soldered to the board through a ball grid array BGA. Those ball grid arrays don’t like thermal expansion fatigue which is exactly the reason for the failures. I have three choices now:

1. replacing the logic board (very expensive)
2. reflowing of the Northbridge (may work)
3. buying a new computer

After trying the reflow I give up with my G5 and go to choice 3. Very frustrating.

Symptoms

Power-on LED illuminates, fans and processor pump run harder, there is no boot and the system shuts down within a few minutes.
Red internal LED lights #2 and #7 come on during start up.

It just happened, kind of like sh**.

Diagnosis

Logic board failure, possible processor failure. Diagnosed by Apple tech at a local Apple store after running hardware diagnostics.
Cost estimate of repair of logic board is $1900 and to replace processor is $900+.

Repair history

It would cost almost as much as this machine cost new to repair. No way should I have to pay that for a machine not even 4 years old.

Too expensive to repair.

Miscellaneous info

One of the worst technology purchases I have ever made. I have been an Apple fan for years. I will start to look elsewhere for computers after this. I may start taking up Apple on their switch commercial.

No

Symptoms

The monitor went black while typing an e-mail. I had to force quit, holding the power button down, and when restarting, the fans would start up, but it wouldn’t boot up. The power light on both the computer and monitor lit up, but would flash brightly 3 times, over and over. Eventually the fans would begin revving up to the point where I would have to do a forced power down.

Diagnosis

I took it to an Apple authorized repair shop. Diagnosis: failed logic board.

Repair history

When brand new, the computer had problems with video in iMovie and Final Cut Express–interference lines kept flashing in the video. Apple repair tried everything to no avail, until both processors were replaced, under warranty. Since then, the computer performed flawlessly, until now.

Symptoms

Ran flawlessly for 4 years then woke up one morning turned it on - nothing! Same symptoms as others - managed to start it up a few times then freeze. Tried everything suggested by techies to no avail. Swapped out RAM, hard drives, Video Card etc. with known working ones. I’m definitely up for a class action. I have Mac IIci, 7500, G3, G4 - all still working.

Diagnosis

The Hardware Profile of AHT reports processor as @1702037.8GHz instead of 2 x PowerPC G5 2.7GHz. Boot into firmware and device tree only sees one CPU instead of two, so I suspect one CPU dead or logic board.

Repair history

Symptoms

Have had for almost five years but with a year’s non-use while we were overseas.

A few months back started freezing, kernel panics. Tried different RAM sticks, seemed to help. Then stable for a few months until the other day (Jan 2010).

Now nothing works - all RAM sticks rejected, three flashing lights (bad RAM) even the original sticks.

Diagnosis

Have replaced with Mac Pro but expected G5 to last longer.

Miscellaneous info

Talked to apple today 3-7-2010

Said that this is a well documented problem that would have been covered if it happened within new-3 or 4 yrs old, but my 5 year old unit is “beyond the life we consider it will last, and therefore is considered common wear and tear,” even though it is a recognized issue/flaw with this model. I said 5 years is an acceptable life span for a +2,500 computer? He said that’s longer than we guarantee it will perform, and because of that there’s no way Apple can help. That sucks.

The unit worked fine the previous day, then the following day only the fan worked.

Diagnosis

Local Apple Dealer-Repair Depot indicated the “logic” board was done, much to my surprise and dismay since this unit is just two years old.

Repair history

None

Miscellaneous info

Contacted Apple Canada and despite my best efforts to indicate that I was a loyal Apple Consumer (I currently have five Mac products including an 11 year old G4 that has not failed me), a Senior Advisor I spoke with would not entertain the fact that there must be a quality issue with the logic board. Basically one of his responses was that I should have purchased the Extended Warranty. Another response of his was that it would be unfair to Apple shareholders to repair my unit; funny he did not think of the situation as being unfair to its customers like me to have a unit failure like mine? Re the Extended Warranty issue, I had previously purchased this Add-On for my MacBook laptop, figuring that this unit would likely fail at some point, I had not considered that the professional grade Mac Pro would, especially after two years.

My final thoughts expressed to the Apple rep was that upon my next computer purchase I will indeed consider looking at other computer manufactures since it appears to me that Apple Canada does not stand behind any of their products, especially in premature failure situations.

Dead logic board or dry solder on logic board, took out the ram in pairs, re seated it etc. Tried the ram in another machine no problems there. I can get it to work if I heat the motherboard and ram with a hair dryer. Fault diagnosed by me and the internet

Symptoms

I woke up this morning, woke my computer. make breakfast and screen froze.

Force quit, restart. Same problem, now with black screen. Noticed power button blinking sets of 3 flashes followed by a 5 sec of no flashing.

Searched for this problem on my MBP. Foud it means RAM failure/bad sockets.

Over the next 2 hours, I tried different RAM configurations. Sometimes it booted, but would crash/freeze soon after. After ~20 attempts to restart, I gave up and read quite a bit about this problem online.

Diagnosis

In a nutshell, bad solder joints caused by ROHS-complient solder. Coupled with daily sleep(cold)/wake(hot) cycles, I assume fatigue cracks in the solder joints finally became intermittent.

The hair-drier-heating-the-ram-slots trick proved innefective.

It was not the hard drive, as I booted my MBP from the G5 hard drive. It’s running fine as I type this.

Repair history

Superdrive died while still under the Applcare 3-year warranty. Apple sent me a new unit quickly. Just last year it acted up again (not reading discs). Turns out the drive just needed a firmware upgrade.

Miscellaneous info

I do not have the serial number handy. I also purchased it in Aug 30, 2004. The above feilds didn’t let me select that date.

There have been a few out there that have removed the motherboard and re- heated the solder joints. I don’t have the time for that.

I would say nearly 7 years witout major problems is pretty good. Should have lasted longer, though. Time to upgrade to a Mac Pro.

Symptoms

Having owned the Quad G5 2.5 years ago and sold only to complete my transition to the Mac Pro, I decided to go back to a G5 Quad. I purchased this from a seller on Amazon who was very nice and told me he has never had any problems with this machine at all. The only problem he had was it needed a replacement power supply - this was part of the recall by Apple for those whose serial numbers fell in a certain category for a free power supply replacement.

I have now had the machine for a few weeks.. the only problem I detected on it was that the Air Deflector sensor board broke off - still baffled on how this happened.. This was a 50 dollar repair though. Now the sensors all work and the little LEDs light up, letting me know things are A OK - Red, Yellow, and Green - these are the power on LEDs.

No other major problems at all.. its a strong performer.. Did I say that right? It is right now in place of my 2010 mac pro and is hooked up to the LED 24 inch cinema display..

Not a bad machine at all.. never a problem with the LCS - Uses the Panasonic LCS and not first revision Delphi.

Diagnosis

No problems with LCS at all.. Logic board is strong and like new + mint. Only problem was a broken sensor board - replaced for 50 bucks and now all the power on LEDs work. LED 3, 4,5

No other problems detected - runs great!

Repair history

2007 Power Supply was replaced by original seller.. no problems ever since.

Symptoms

Gray screen on startup, then fans getting loud like a jet engine. Black screen on next startup. No response to resetting PMU, but gray screen returned. Was able to enter commands in ‘Open Firmware’, but would lock up when enter “reset-all.” Subsequent startups would go to black screen. Fans would still run, then get loud after a few minutes.

Diagnosis

From troubleshooting battery, RAM, hard drive, and peripherals, problem appears to be the logic board. Was able to apply heat to the logic board with a hair dryer and magically bring the machine back to life for an hour or so, after which it locked up and tryed to take off (loud fans). Next attempt to apply heat only provided a few minutes of life.

Repair history

No prior problems with this machine. Did not attempt to repair this problem - cost of new board not worth it.

Symptoms

Finished using it, logged out. Fans slowly increased to max, so tried to do a restart. System shut down instead, and then would not boot (black screen, keyboard not active, no chime). Heating the BGA area with a heatgun on low temp will get it to boot.

Took it to Apple store… genius looked at it and reset some things (didn’t say what, but I would guess NVRAM, PRAM, etc.) Reseated memory. System booted. As far as I know, no diagnostics run. Would not boot when brought home. I did manage to get it to boot later that night, and ran AHT DVD. Passed everything up until RAM testing. I stopped the testing after more than an hour (3Gb of RAM). Probably locked up during testing, but I’m not sure. WOuld not boot after that. Got it to boot the next night, and ran memtest in single user mode… it passed 2 passes of that. Would not boot later (fans went to max and it had locked up).

Found the thread on https://discussions.apple.com/thread/1672650?start=195&am p;tstart=0, read about the hair dryer/heat gun, resoldering and decided to give it a shot. Only way I can get it to boot. It will run for 12 hours or so (long enough for a full disc image, so I am backed up).

Even though this was a refurb through the Apple Store, I am a long time Mac user (like most of you) and expect their hardware to last for 10 years or more with little if any trouble. So yes, I am a bit pissed about this, particularly since it appears to be a production process/design problem (I work int the electronics industry and am a former tech in the semiconductor industry).

Diagnosis

Bad RoHs soldering on BGA, possible bad joints on RAM DIMM, maybe others. Diagnosis from Apple genius: “I don’t know, but you know these systems are vintage, and we can’t supply parts anymore”. Most helpful :palm:

Had BAD RAM from Crucial around December of last year (2010). Replaced (RMA).

Symptoms

Exact same symptoms as every other PPC 2GHz G5 (2004) Users [i.e. Won’t boot regularly (or at all!) - sometimes boots with x2 CPU but will soon/immediately freeze/lock-up, requiring a reboot, then, back to same scenario of not booting-up again OR occasionally boots successfully with only x1 CPU, which can sometimes run for over a week (without rebooting!). When using verbose boot (Cmd+Shift+V) the machine hangs immediately at DART enabled - on a successful boot the boot sequence rapidly passes DART enabled. When hanging, the boot sequence invokes the high fan activity after a few minutes.] I am now making personal enquiries regarding purchase/replacement of Logic Board. Will eventually attempt the hairdryer technique to see if a reflow will lead to a successful boot. Doesn’t/Can’t boot from Apple’s Emergency Disk either.
