Question about Apple iMac G4 Desktop

2 Answers

IMac G4 completely dead!

I have researched this issue and it appears that everyone has a different opinion on how to fix it and what the root cause is... Mine was working perfectly, I bought the new 24" and layed on the closet for 6 months. When I tried to use it again, this time nothing happend: no fan, no screen... First I changed the battery (that did not resolve the problem); then I press the button for memory reset (yes, only once), that did not work either. I ordered a power supply, changed it and that did not help either. Please, help, I have most important documents in it (after I migrated everything to the new iMac I added some stuff) and I need access to them. Any thoughts??

It sounds like you may have tried this already, but I'm not sure.
Unplug the computer, disconnect the power supply form the logic board, and remove the battery completely. Let it sit this way overnight. Reassemble it and try again. It dissipates latent electricity from the board.

Well if a new power supply and battery and board reset didnt work you have hit all the stuff it might be other than the board itself.

Best way to retrive your data is get a external enclusure put in the hard drive and plug it into the new Imac.

I have found sometime people have bent or unplugged some ribbon cords in the Imac and they are finicky after that but since yours just happened I am not sure.

Hope this helps. Sorry your Mac isnt playing nice.

No chime no fan no screen on Imac G4 17', even after reset of the PMU


Could be a problem with the logic board. If you have Applecare, take it to an Apple store and they might be able to fix it. Otherwise, it may be dead.

Imac g4 won't start but shuts down when apple logo appears on screen


Are you sure the iMac is really shutting down or just turning off the backlight? The tell-tale sing would be to let the unit fully boot-up (wait 3 minutes) and the press the button the apple keyboard that ejects the CD-ROM. If the CD-ROM door opens, you iMac is running with disabled or broken backlight.
The inverter circuit on the iMac G4 is known to be weak.
There could be another problem, though. The iMac G4 is also known to have weak internal power supplies. Here's how you can tell:
Hold down the CMD OPT "O" and "F" keys at the same time while pressing the power button. This will tell the iMac that you want to boot into the Open Firmware shell, bypassing the Mac OS X startup. If this works, your power supply is good, the inverter is good and you have a problem with your Open Firmware boot string. To fix the boot string, Power on the unit while holding down the keys CMD-OPT-P-R to zap the parameter RAM (PRAM) and reset everything to defaults.
If you were not able to boot into the Open Firmware shell, your problem is either a failed power supply or a failed screen backlight. The last possible culprit is your iMac could suffer from "Bulging Capacitor Syndrome", where a batch of iMac G4s, iMac G5s another electronics were fitted with a bad batch of capacitors. Eventually, the caps will rupture and cause irreparable damage to the logic board. Only way to verify this is to pull the unit apart and visually inspect. If you see little green or blue cylinders that seem to be bulging or oozing a thick oily goo, that's your problem. Only recourse is to shop around on eBay and look for a replacement logic board.

If your iMac is an Intel Core 2 Duo running Leopard, it's certainly not a G4.
From the symptoms described, you have either a bad LCD panel or a bad LVDS cable. Either way, what the tech told you is wrong. They can both be replaced. Whether it is cost-effective or not is for you to decide.

APPLE IMAC G4 - TRYING TO INSTALL OS WITHOUT DISK EJECT BUTTON


Reastart the iMac and at the same time hold down the mouse left click button. If that does not work.
  1. Restart the computer.
  2. Immediately after the startup sound, press and hold the key combination Command-Option-O-F.
    Note: The Command key has the Apple and (commandkeysymbol.gif) icons on it.
  3. Release the keys when you see a white screen that says "Welcome to Open Firmware."
  4. At the prompt, type: eject cd
  5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and "ok" appears behind your command when the action is complete.
  6. Type: mac-boot
  7. Press Return.

Imac g4 dead


Hello, The power supply is part of the motherboard in the iMac G4, so it's hard to change it. The repair would certainly cost more than the price of your iMac. You can try to take off the small battery, and reboot it to see if it changes. To open the mac lay it down, screen on the table (on a t-shirt). Unscrew the four screws (they wont come out, so just unscrew them. Pull the screws and take off the silver plate. Then you'll have access to the inside. Good luck

IMAC snaps off during operation Console says cause - 122


Sounds like a power supply issue. You will need to take this to an apple dealer and ask them about it. This one is not an easy fix as it is a hardware fault.
