You can check the LED lights inside the computer to see if it's a power supply problem.  Apple's web site has the support troubleshooting section.  You can look for the info that tells you what they each mean.  What they don't tell you is how to start the computer without the back on.  You will have to get the info from the web site for the rest of my message to make sense.  Find the info that has the pictures of the inner part of the computer.  
Then find the two small buttons one above the other to the left of the LED lights.  If you press the one on top your computer will turn on.  From that point at least you'll have a better idea of what the problem isn't.

Call Apple, I have a friend that had the same problem. Not sure if it's the fan or the power supplied to the fan.

Ok, the school where I work was having an electronics recycling drive and one of the other labs recycled an iMac G5 A1058. I have a friend who needs a new computer, so I took it, got a new hard drive for...


Bad capacitors often cause the no-turn-on problem. This page has a good picture of what bad caps look like in the G5. If you see this trouble in your G5, you might be able to get this going. Kits of capacitors are available (here's the place I got some from) and If you're comfortable with electronic soldering and replacing parts on a printed circuit board, changing out the duds may be all that's needed. I've seen three of these now. On one, there was just a single bad cap that was keeping the computer from starting up. It's certainly worth looking into.

G5 keeps powering up for a few mins then switches off?


Thank you for contacting Fixya Support, I am glad to assist.

There are a few steps you can try to troubleshoot this issue:

Try a PMU Reset:
* Turn of your iMac if it is already turned off
* Disconnect all connections to the iMac except the power cord
* Now disconnect the power cord for approximately 20 seconds
* Reconnect just the power cable the keyboard, mouse and power cord, and then power your iMac G5 up.

* Check to see if the iMac boots up normally without power interruption.

* If the iMac G5 shuts off again, try these steps, another recommendation would be to remove all connections including the power cord, and lay the iMac G5 on soft cloth face down and with a philips screwdriver, remove the plate on the bottom of the iMac G5 where your RAM memory is located.
Before removing the RAM however, touch your hand on the metal boot to discharge any static current you carry for approximately 5 seconds.

Now remove each RAM card and then reseat (re-install) each card.

Restore the RAM card cover with your Philips screwdriver, reconnect your power cable, keyboard an
d mouse and turn on your iMac G5.

See if this second procedure helps if the first procedure does not work.

Let me know if this helps.

Regards

Camcorder wont work with mac os x


Your camera will not work with Mac period. It is a digital camera but is outputting an analog signal. Been there and done that with a TRV camera myself. There are lots of cameras that will work with your G5 Mac. I am now using a Sanyo VPC-HD 100 with my Intel iMac and it works great. Click the link for some supported cameras. This is not all of them. http://support.apple.com/kb/TA20587

Power up IMac but screen blank, fan on, light on but no response


I have one doing exactly this at the moment. It had gone to sleep and the fans were going like crazy. I think it is a Motherboard failure (it happened with many G5 iMacs), this one has been replaced once already, and I can't actually get it to install anything. I'm taking it apart tomorrow to see what I can find inside. If I fond anything I'll let you know.

Imac g5 is so noisy


Fan sometimes get stuck on, I won't bore you with the technical details as to why or the terminal command to fix. Just do this...
Shut down. Unplug the power cord from the back of the tower. Wait 15 minutes and plug it back in. Power up, it should have reset it.
The fans are "smart", some of them are designed to run only as needed, sometimes they get a little tangled up in their own underwear.

Make sure all cables are disconnected. Make sure you are only undoing the three silver screws along the lower edge of the unit. (These are captive screws and should not be removed).There is one screw at each end and one in the middle. Tilt the cover up and lift it away from the computer.

Screen Changes and Comupter freezes


It may be possible that the power supply, display and or logicbpard may be having issues. Apple recommends resetting the pram and nvram. If issue persists reset SMU. YOur machine is 6 months outside of the original warranty, but if you purchased the 3 year extension plan, you may want to take action on it.
