Question about Apple iMac G4 Desktop

1 Answer

Apple iMac Not sure how this is supposed to work. This is a reply to pyrhyc's answer to my original question regarding replacing 256mb chips. I did go back after the original installation of the second chip which ended in failure and replace that chip with the original that came with the machine. No luck, still the orange light and no power up.

This is just a narrowing down process to determine where the exact problem is. This could be a processor problem, but I really think that it's with the memory. You can narrow down the problem to a bad chip, and which chip, if you put only one chip in at a time. The machine will run on only one chip, it does not need both, and by putting two in you will not be able to determine if it's a bad chip or which one.
Check and clean the second slot to be sure that nothing is up in it, and check the processor for the proper seating. Then try the machine with only the first chip in the, no chip in the second slot. If none of the chips work, new or old, in either the first slot or second slot by themselves, then you know that the problem is elsewhere, and that you may have damaged the processor in changing out the memory. This is the process of elimination that any decent tech uses in diagnosing the problem.

Fan does not run, over-heats


Thank for contacting Fixya, I will be glad to assist you.

In such extreme situations like this, the very fact that you have taken your iMac in four times to either an Apple retail store or an Apple Authorized service provider and having those repairs/replacements performed still with no resolution, is a sign your iMac may actually need to be replaced.

From my experience as veteran Mac tech, if your computer has been repaired at least three (3) times and there is still no resolution to the issues it has been having, you should be able to get a replacement computer from Apple or one of its authorized service providers.

Given the extent of the repairs that have been performed, I would recommend you take this computer back to your local Apple store and find out what is needed to acquire a replacement iMac.

The main reason I am being so direct in this answer to you, is not only due to the number of repairs you have experienced on this computer, but also the fact that of those repairs/replacements, the iMac's main logicboard (i.e. "motherboard") was replaced, yet you are still experiencing issues with your iMac's fan not running and your is also still iMac overheating.

This is a genuine hardware issue for sure so this is the course I recommend you take. One additional point I also need to add however. I noticed you never mentioned that the Apple retail store or the Apple Authorized service provider checked, repaired or replaced the fan which stops running and causes your iMac to overheat.

That is one component you need to have checked by a Mac technician, only because if the fan is still not running, even after the main logic board has been replaced- that still constitutes the problem you are having is still relative to the hardware, not so much the software.

If you have more questions, please don't hesitate to reply back to this post.

I have an Imac 21.5 mid 2010 edition. my optical drive won't take in an cd. when i push the past the point where it is supposed to be sucked, it's like something is pushing it back out, gently.


Hi Mark,

Get in touch with Apple. You are still in warranty. They will probably advise you of an authorized service centre to take it to where it will be fixed under warranty....for free.

Hope this helps!

I have an iMac 17


Thanks for contacting FixYa Support.

I have repaired numerous iMac G5 17" models for a while now and because I have, I can tell you just from the symptoms you have described, this is potentially a power supply issue.

However, the iMac G5 17" have been known to have swollen capacitors, which can also ultimately impact the power management / performance of your iMac.

If you are able to, very carefully and don't touch them, you can look on the iMac's main logic board to see if you notice any swollen capacitors. If you are not sure what a capacitor looks like, they look like mini batteries connected to the board.

Should you do this and find that the capacitors are ok, then I would recommend for sure, that you look into replacing the power supply.

For your model of iMac 17" provided it is not an Intel-based iMac, the part number you will need to source is part# 661-3627. Below, I have also provided the most inexpensive price for this iMac power supply per this link:
AppleComponents.com

You may find even lower prices for this iMac 17" power supply, if you search online further, but this is one of the better online Apple components vendors. Therefore you should be able to see and compare the prices on this website, with some of the other vendors
advertising the same Apple power supply for the iMac 17".

I hope this helps. If you have any more questions on this subject, simply reply back to this post.

Best Regards,

I have not been successful to config my mailing account on iMac Mail, with my BSNL, India account.


font.f1 {font: 12.0px Times} Hello and thanks for contacting FixYa Technical Support.

When it comes to setting up Mac OS X Mail with your BSNL
email account, because it is not a US based email account, Apple has specified that the Mac OS X Mail application will only support US-based emails. This more than likely will explain why you are unable to configure Mac OS X Mail with your email account.

I have provided the link below from Apple detailing this information.

Apple Support Link:

If I can be of further assistance, please do not hesitate to reply back to this post.

HL-DT-ST DVDRW GA11N problem


With your Superdrive being dead out of the box, there is no need to be burdened with it.

Whenever you purchase an Apple Desktop or portable notebook, it automatically comes with 90 days phone support and 1 year of hardware support. So you can simply contact Applecare Support at 800-275-2273 (make sure you have your iMac serial# ready) to get that drive replaced under warranty of course.

But it may be even easier to take the iMac back in from where you purchased it and get that drive replaced or get a new iMac 21" from the store you purchased it from, unless it was via an online seller like apple.com direct, or any other Apple-authorized reseller online.

Considering your model is so new, I would recommend that course of action. Now if you are getting some functionality from that drive, then let me know and I will provide some troubleshooting procedures for you.

Regards,
