SOURCE: iMac G5

If it isn't the power supply, some of the early G5 imacs had a capacitor failure issue...mine just died, in fact. It was just shutting off by itself, even turned on once by itself....but tonight, when it shut down, it would not restart. I opened it up and looked and sure enough, 11 bulging/leaking capacitors. My local service center says there are two options: 1. new mother board-aprox $500 or replacing the capacitors- between $170-200. Until Dec 15, 2008..this was apparently covered under a special warranty extension program Apple had....typical!

If you still have the installation disks, try doing a reformat hoping its a driver error. But, sounds to me it may be something wrong with your panel. Take it in the genius bar to get it looked at.

SOURCE: I have a apple Imac g5 that only boots colored screens

The first thing I would do is boot up in safe mode see http://support.apple.com/kb/ht1455 this will boot the imac up without extensions on that includes video extensions which could be the source of the problem. See if the screen works after this, if it does it could indicate that the either video card is not operating properly or one of the drivers isn't. If you then search on google for your model of card and see if this is a known problem and you could find a work round.
If it boots up as you have described it in your email it's a possiblity that the card is no longer functional and it will be expensive to repair.

Tascam 244 to imac G5 via line in


This will work just fine. There may be a little hum and noise but this is to be expected from this kind of signal input. Alternatively you would need to get a specialist audio input device. I can recommend M-Audio devices

This could be one of two issues: 1. Bad processor which is what I suspect is most likely 2. Bad video card; less likely since you'd still be able to click on icons etc.

About 6 months ago there were 2 colored vertical lines on my desktop screen. I've been getting more lines every 2 or 3 weeks and now have a total of 18. The nearest Apple store said they can fix it no...


It should not affect the data on the hard drive but with all repairs such as this it always worth making sure you have your hard drive backed up. I had a similar problem with a imac a couple of years ago and the hard drive was fine when it came back. Hope this helps.

How do you use an external microphone with the imac G5, and what type of microphone isd needed?


The iMac G5 does not have a microphone in jack, only a line in jack. The signal levels are generally not compatible.
You can buy a USB-based microphone (or headset), or you can buy a preamp unit such as this iMic.

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...


Sir,
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.


Thanks
Good Luck

COLOR VERTICAL LINES.


Vertical lines are problems that usually arise from either a bad lcd or video card ( GPU).

There is no fix, other than replacing the bad part.

If you want to do it yourself I've got service manuals, but unless you have experience it's no walk in the park.

Is it still under warranty?

You might be able to get an extended warranty through AppleCare.

17" iMac quit working



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: http://www.jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php.  (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
