Note About Images in This Manual
Because a pre-production model was used for most of the images shown in this manual, you may
notice small dierences in appearance between the image pictured and the computer you are
servicing. However, although the appearance diers, the steps and sequence are the same unless
noted.

Serial Number Location
iMac serial numbers are located on the bottom of the computer stand. Note: iMac computers
using Intel processors will not have the G5 listed in the conguration (as shown below).
iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — General Information 7
Safety
Warning: When the iMac is under power, be aware that the power supply contains high voltages
that pose a potential hazard to your personal safety. Never work on or near the power supply
with the unit powered on, and as a further precaution always make sure the unit is unplugged
when working on it with the front bezel removed.
WARNING: HIGH VOLTAGE
Text or photographs marked by this symbol indicate that a potential hazard to your personal
safety exists from a high voltage source.
The power supply board is a high voltage source with the unit under power, and remains
powered up whenever the system is plugged in, whether or not the system is turned on. Use
extreme caution when troubleshooting the system with the front bezel removed.
Disconnect power to the system before performing maintenance.
•
Don’t work alone. In the event of an electrical shock it is important to have another
•
individual present who can provide assistance.
Keep one hand in your pocket when working on any iMac that is plugged in. This will
•
help ensure that your body does not provide a path to ground in the event that you
accidentally make contact with the line voltage.
Don’t wear jewelry, watches, necklaces, or other metallic articles that could present a risk
•
if they accidentally make contact with the power supply circuitry.
iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — General Information 8
Opening the Computer
Apple authorized, desktop certied technicians only should ever remove the front bezel on the
iMac. When the front bezel is removed, be sure to always ground yourself and follow ESD-safe
repair practices
Removing the front bezel requires using a special access card (part 922-7172) to release latches
located inside the upper corners of the front bezel. Slightly bending the upper quarter of the
access tool card will help engage the latch more securely.
As you are inserting the card to disengage the latch you should squeeze the top of the bezel,
that will help take pressure o of the latch and enable it to open easier. Note: If the bezel won’t
open, read the next topic, Access Tool Modication.
Once the card has been released it is safe to open the bezel. See the Front Bezel Take Apart
procedure for more information.
Access Tool Modication
If you wish to modify the access card tool, order kit 076-1213. The kit contains an access card and
a piece of EMI gasket that can be cut and added to the top of the card. The additional thickness
on the card will improve the contact with each bezel latch.
Remove the tape on the gasket to expose the sticky side of the gasket. Attach the sticky side
1.
of the EMI gasket to the top of the access card.
iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — General Information 9
Cut the EMI gasket to the edge of the access card.
2.
Using packing tape, or something equivalent, fold the tape over the EMI gasket to attach the
3.
gasket to the card.
iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — General Information 10
Bend the card at a slight angle at the top to make sure the card makes contact with each
4.
latch.
Refer to Removing the Front Bezel for the complete procedure.

EMI Shielding
The iMac enclosure is wrapped in EMI shielding that is easily torn and damaged. To maintain
a properly shielded unit, you must repair all accidental tears and cracks to the shielding by
covering them with EMI tape. Order EMI tape, part number 922-4786 (a long, thin strip) or 922-EMI tape, part number 922-4786 (a long, thin strip) or 9225026 (short, wide strips).
Cover nicks, such as the those shown below, with EMI tape. Pay particular attention to the EMI
shielding inside the rear housing, shown below. The EMI shield is easily damaged when replacing
modules.
iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — General Information 12
Lower EMI Shield
EMI tape covers the top and sides of the display panel, and the lower EMI shield covers the logic
board along the bottom of the unit. The EMI tape and lower EMI shield are easily damaged when
removed, and removal is necessary in order to access most components within the unit.
Should the EMI tape that seals the display, or the EMI shield covering the bottom of the
enclosure (see photo below) accidentally tear, use EMI tape (922-4786 or 922-5026) to repair and
completely seal the unit.
When properly repaired, all edges shown below will be wrapped by EMI tape, and the tape
securely adhered to all edges. Use a black stick to atten the EMI tape tightly and rub out air
pockets and wrinkles.

What’s New
23 April 2007
•
The optical drive removal procedure has been updated. Using a screwdriver to release the
optical drive tabs is causing damage to the logic board. The updated procedure shows how
to remove the optical drive using a needlenose pliers.
•
Additional information on handling slot-load optical drives can be referenced in Kbase
article 305282.
12 January 2007
•
The “No Power” symptom in Troubleshooting has been updated. If your computer won’t
turn on, try removing and reinstalling the SO-DIMMs.
31 October 2006
•
Troubleshooting has been updated with a new symptom, “Fans running at full speed after
computer turns on.” Note: The customer may have entered a diagnostic mode that causes
the fans to run at full speed. This symptom is very easy to resolve at the customer level.
3 October 2006
•
The symptom “Starts Up To Black Screen or No Video (iMac 17-inch Mid 2006 only)” has been
added to the troubleshooting chapter. Upgrading to Mac OS X v10.4.8 resolves the issue.
2 October 2006
•
EMI tape photos (922-4786 and 922-5026), used to repair torn and damaged EMI shielding,
have been added to the EMI Shielding section in the General Information chapter.

About the Power Supply
Warning: When the iMac is under power, be aware that the power supply contains high voltages
that pose a potential hazard to your personal safety. Never work on or near the power supply
with the unit powered on, and as a further precaution always make sure the unit is unplugged
when working on it with the front bezel removed.
WARNING: HIGH VOLTAGE
Text or photographs marked by this symbol indicate that a potential hazard to your personal
safety exists from a high voltage source.
The AC/DC power supply board is a high voltage source with the unit under power, and remains
powered up whenever the system is plugged in, whether or not the system is turned on. Use
extreme caution when troubleshooting the system with the front bezel removed.
Disconnect power to the system before performing maintenance.
•
Don’t work alone. In the even of an electrical shock it is important to have another
•
individual present who can provide assistance.
Keep one hand in your pocket when working on any iMac that is plugged in. This will
•
help ensure that your body does not provide a path to ground in the event that you
accidentally make contact with the line voltage.
Don’t wear jewelry, watches, necklaces, or other metallic articles that could present a risk
•
if they accidentally make contact with the power supply circuitry.
