Use this guide to replace your logic board.

Insert a plastic card up into the corner of the air vent slot at the top of the rear case.
-
Push the card toward the top of the iMac to release the front bezel latch.
-
Pull the front bezel away from the rear case.
-
Repeat this process for the other side of the front bezel.
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.

Remove the four recessed coarse-thread 7.5 mm T10 Torx screws securing the display to the rear case.
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.
