  • It may be necessary to apply several layers of duct tape to the top of the access card to aid in releasing the latches.

  • If the bezel refuses to release, try pressing the lower edge back onto the rear case and repeat this opening process.

Using a strongish magnet will grab and release the latches.

Are you sure it's safe to do this? How close is the hard drive, won't magnets interfere with it?

It's almost certainly fine. Modern hard drives are very resistant to magnetic fields.

No problem taking those screws off, HUGE problem trying to put them back in. Reassembling this step is a lot more complicated. Those 4 screws are impossible to reinstall if you don't have a magnetized screwdriver, which I don't.

I used some 'chapstik' on my t10 driver and it held the screws long enough to insert them.

Since I could not get a hold on a nice magnetized T10, I inverted the whole unit and worked upside down to avoid lost screws inside an iMac.

Great, now my problem is to find a new cable that connects the panel to LB.

I'm from Italy and nobody has got it .

Please help me

Thanks for all

I found a group of wires not mentioned on the instructions along the underside of the display at the right. They were connected to something at the right bottom of the display near the white plastic piece. I am unable to raise the display more than a couple of inches at this side of it and am wondering what do do.

The group of wires on the right side of the display is the inverter. Seems like a few steps were omitted, so I'll try to fill in the gaps. Use the T10 to remove the right speaker. It's the big white plastic squarish thing on the bottom right side of the iMac. It pulls stright up and you can either disconnect it or just leave it hanging. This should release the inverter cable from hanging up the right side of the display (it did for me, even disconnecting the inverter didn't help as the cable was under the speaker, the inverter doesn't need to be disconnected but it might be helpful to disentangle things and it's an easy one to take apart). The other step missing is to remove the perforated tape at the top of the LCD from the LCD, otherwise you can't really remove it. I found a spudger helpful for this task.

I know it's a couple years since the OP posted, but hope this helps someone.

I've found that 'coating' the tip of the screwdriver with glue from a glue-stick will help to keep the screws from coming off of a non-magnetized driver.

  • Pressing the top of the hard drive bracket down to release it from the rear case requires a substantial amount of force, so we recommend laying your iMac stand-side down on a table to avoid knocking it over.

I disconnected the hard drive bracket and slid it to one side and removed it, then removed the hard drive (squeezing it out just wasn't working for me).

Before I discovered IFIXIT I had purchased a hard drive from Western Digital and am hoping it is the correct one for my 17" iMac G5, 2 GHz Intel Core 2 Duo. The WD drive's description is TRESXLB2 7200 64M SATA3 6GB/S 1.0 TB 2HD STD . Can anyone tell me if I will have problems with this drive? Western Digital's recommendations fit this description for my iMac. Thank you. Ron
