Question about Apple iMac G5 Desktop

Screen Changes and Comupter freezes

Our 18 month old iMac G5 has recently stopped working properly. After a short period of use (5 - 20 minutes) the display morphs into what looks like a hazy bluish overlay of a series of vertical and horizontal lines/boxes. It also freezes. HELP! Any ideas?

    Thanks for the suggestions. The iMac G5 won't even boot up properly
    so I am unable to even try your suggestions. (Did open it up to try
    and see if it was the power source. It wasn't.)

    Of course we did not get the extended warranty. We have never really
    used applecare before and until now have never needed an extended
    warranty for any of the other apple computers (3) we have purchased in
    the past. We bought a Macbook 3 months ago and have 3 children who
    will all be going off to college over the next 4 years .... so we will
    continuously be in the computer market. To say that we are
    disappointed in the longevity of our babied iMac is an extreme
    understatement. My husband believes it is the "motherboard" (same as
    "logicboard", right?) and is voting to go back to a Dell. I am
    communicating via our 4 yr old Dell at the moment. It has been through
    heavy construction, damp basement conditions, and many hours of use and
    is still going strong. Sorry for the venting but .... ahhhhhh!!!

    Called Apple. Was told we were covered. Was given a case # and a repair ID #. Next morning, went to the apple store with this information and they told me our machine was not covered! They also claimed there was no record of my call with Apple customer service the night before. FRUSTRATION mounting!

    I agree that Macs are generally excellent machines which is why we have now purchased 5 mac systems over the years. Not needing any of the "services" offered by the genius bar and this machine being a babied desktop, we did not purchase the extended warranty. This looks to be a widespread problem related to the manufacturing. Apple should stand behind their product. It is disappointing that they have not done so.

    This has not been a very "cost effective" purchase - with the initial purchase price plus the estimated cost of repair our per month cost of ownership would be over $1,100. That's a whole lot of Dells/HPs/etc....

If you are lucky you may qualify for the extended repair program from Apple.

Read about it here:

If not you may want to join the others who don't have AppleCare and are not too happy.

Less sympathy found here:

If enough people complain Apple may extend the repair to more serial numbers as has happened in the past. Macs are generally excellent machines and well worth the money but problems can arise in manufacturing considering the widespread sources computer companies must use to compile their product.
Good luck, let us know what happens.

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.

Keep me posted.

    Dell? Very cost effective, but as with all things, you get what you pay for. Macintosh produces the hardware and software, no other computer company can say that. In my repair experience, i've seen more dells hit the junkyard then macs. Good luck.

I have an iMac G5 2Ghz that when it start up you can only see video for a few seconds. I connected an external monitor and my iMac works fine but with its on LCD there is no video. I check the logic board...

The iMac G5 and iMac G5 (Ambient Light Sensor) computers have a video out port located on the back of the computer, which will mirror video. Video mirroring means you can see the same image that is on the iMac G5's flat-panel display on an external monitor, television, or projector.
Using the video out port, you can mirror video with a compatible VGA display using the Apple VGA Display Adapter.
You can also use the video mirroring feature with a television or projector that has S-video or composite video connectors when you use the Apple Video Adapter.
Both the Apple VGA Display Adapter (M8639G/A) and the Apple Video Adapter (M9109G/A) are available separately, and are needed if you want to use your iMac with a VGA monitor cable, S-video cable, or composite video cable.
The video mirroring feature is "plug and play". Simply connect a VGA display, television, or projector to the appropriate adapter (see above), then connect the adapter to the video out port located on the back of the computer.
When you connect the adapter to the computer, the screen may refresh momentarily as the computer prepares itself for the new video output. The computer tries to match the resolution of the built-in and external display. If there is no match, the computer changes both screen resolutions and may black out areas on the built-in display in order to match the capabilities of the external display.
Important: To ensure that your iMac G5 automatically detects the external display or projector, be sure you plug the adapter into the external display or projector before you plug it into the iMac G5.
You can switch resolutions and frequencies for both the iMac G5 flat-panel display and the external display, television, or projector using Displays preferences.
Want to watch a DVD movie disc on a television that's connected to your iMac G5? Select a 720 x 480 NTSC (in the United States) or 720 x 576 PAL (in Europe and other regions) resolution in Displays preferences.
Tip: Because of the display limitations of most televisions, the images displayed on a television screen are usually not as high quality as those on the built-in display or an external monitor.

Good Luck

Hi, it seems like a motherboard problem (hardware), you will probably need to bring the mac to an AASP. Before, you can try the Apple Hardware Test, or resetting the PRAM (Hold the cmd, alt, p and r keys)

Your Imac may be one of those affected by Apples purchase of inferior capacitators from Taiwan. If you are less than 3 years from the purchase date, apple will repair the problem for you for free. Just take the unit to your nearest local Apple Genius or tech. If you are outside of the repair extension guidelines, I have provided a link here which can show you or someone more skilled how to repair the problem. Ordering a new motherboard and power supply will set you back a lot of money, however the following guide and pdf give you step by step instructions on how to ressurrect your dead imac without speding more than $100.00. I was able to repair my imac using this guide and it was worth it to save a $2k computer that was only 3 1/2 years old. Check it out:

the following information (in italics and bold)  is taken directly from:  (this site is complete with instructions, manual and the full compliment of materials available at an extremely affordable and fair price. I took a chance and repaired my own, it is not as hard as it sounds1)

The iMac G5 Repair Extension Program for Video and Power Issues applies to first generation iMac G5 computers that have video or power-related issues as a result of a specific component failure. If your iMac G5 is exhibiting any of the symptoms listed below and your computer's serial number is within the noted ranges, your computer may be eligible for repair, free of charge. If Apple or an Apple Authorized Service Provider (AASP) determines that your iMac G5 computer is eligible as part of the 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.

This is a worldwide Apple program.
Affected systems will exhibit one of the following video- or power-related symptoms:
Scrambled or distorted video 
No video 
No power 
Note: If your iMac G5 is not experiencing any of these symptoms, you do not have to contact Apple or any Apple Authorized Service Provider.

Which iMac G5 computers are affected by the iMac G5 Repair Extension Program for Video and Power Issues? 
The program is available for certain first generation iMac G5 models that were sold between approximately September 2004 and June 2005 featuring 17- and 20-inch displays with 1.6GHz and 1.8GHz G5 processors.

The affected iMac G5 computers have serial numbers where the first 5 digits fall into the ranges noted below.

Serial Number ranges:
W8435xxxxxx - W8522xxxxxx 
QP435xxxxxx - QP522xxxxxx 
CK435xxxxxx - CK522xxxxxx 
YD435xxxxxx - YD522xxxxxx 
Some second generation iMac G5 computers have serial numbers that fall within the upper band of the ranges listed below. Only first generation iMac G5 computers are affected by this program.

Where do I find the serial number of my iMac G5?
The 11-digit serial number is located on a label under the foot of the iMac G5. There is a bar code underneath the serial number.
To view the label, hold the sides of the iMac and gently lay the computer face down on a soft, clean towel or cloth.

Is the iMac G5 Repair Extension program available for other Apple computers? 

This program applies only to the systems noted in this FAQ. Other versions of the iMac G5 line are not part of this program. Click here for more information on how to identify iMac G5 models

IMac clarification

Okay, you probably need a new power supply, this unit had many power supply and logic board problems.  300.00 is a lot for a power supply, 120.00 is the usual cost plus 50.00 labour, and that is canadian dollars, it should be much cheaper if you are in the U.S.

On the Dell, have look at your network connection setup. ( You don't say what OS you have on it ) There could be a box with a tick in it to automatically connect to nearby wireless networks. Disabling this may help.
