eMac Repair Extension Program
for Video and Power Issues
The eMac Repair Extension Program (REP) for Video and Power Issues covers repairs for eMac
(USB 2.0) computers exhibiting issues due to specic component failure. Program instructions
and the CompTIA code for eMac REP repairs are provided in this chapter.
Overview
The eMac REP for Video and Power Issues covers eMac (USB 2.0) models that exhibit one of the
following video- or power-related symptoms:
Scrambled or distorted video
•
No video
•
No power
•
Intermittent system freezes or crashes
•
System crashes during the startup process
•
If an eMac (USB 2.0) computer exhibits any of these symptoms and falls within the eligible
number range noted below, Apple service providers should inspect the capacitors on the logic
board. If the capacitors show signs of bulging and/or venting, the logic board should be replaced.
This program covers aected eMacs for up to three years from the original date of purchase.
Apple will continue to evaluate the repair data and will provide further repair extensions as
needed.
Note: Customers are responsible for the repair cost of any damage caused by accident or misuse,
or for issues that do not relate directly to the specic logic board issues covered by this program.
Eligible Products
The program is available for eMac (USB 2.0) models that were sold between approximately April
2004 and June 2005. The aected eMac computers have serial numbers with the rst ve digits
falling into the ranges noted below:
G8412xxxxxx – G8520xxxxxx
•
YM412xxxxxx – YM520xxxxxx
•
VM414xxxxxx – VM518xxxxxx *
•
* updated as of July 12, 2006
Some remanufactured or refurbished eMac computers (serial numbers beginning with “RM”) that
exhibit the symptoms listed above may also be eligible for repair under this program. Inform
customers that a more thorough inspection will be required to determine if the computer
eMac Repair Extension Program for Video and Power Issues 1
qualies. If the computer does not qualify, contact the customer for resolution.
Note: Some eMac (2005) models were manufactured with serial numbers within the same upper
number ranges noted above, but these models are not covered under the eMac REP for Video
and Power Issues.
The eMac REP covers computers based on their system serial number and the symptoms
diagnosed, not on the serial numbers of the logic boards. All eMac computer serial numbers are
printed inside the optical drive door. You can see this number when you eject the optical drive
tray by pressing the eject key on the keyboard.
Customers are responsible for the repair cost of any damage caused by accident or misuse. For
example, computers that show signs of having been dropped or of liquid spills into the case are
not eligible for the eMac REP.
Customers are also responsible for issues that do not relate directly to the specic logic board
issues covered by this program. For example, if an eMac is taken to an Apple service provider
with a cracked display and a component failure eligible under the program, Apple will cover
the component failure repair, but the cost of replacing the cracked display is the customer’s
responsibility.
eMac Repair Extension Program for Video and Power Issues 2
Repair Strategy
Required service parts for this program are available so that certied technicians may repair
eligible eMac (USB 2.0) computers at an Apple service provider location.
Service providers should create the repair for an eligible eMac in the usual manner, whether or
not the computer is covered by an Apple warranty or extended service agreement. However, it
is extremely important that you select the specic CompTIA code created for this program (see
“Special CompTIA Code”).
Reimbursement Strategy
Apple is aware that some customers may have paid for out-of-warranty repairs that qualify
under this program. If your customers’ eMac was repaired out of warranty and they believe the
repair qualied under the eMac REP for Video and Power Issues, Apple will review their claim and
determine if the customers qualify for reimbursement of the repair cost.
If the claim is determined to be eligible for repair under the eMac REP for Video and Power Issues,
Apple will reimburse your customer directly.
Apple will work with service providers to inform aected customers (where contact information
is available) about details on the reimbursement process. If your service location has conducted
any out-of-warranty repairs that are eligible under this program, Apple will contact you in the
near future to coordinate communications to aected customers.
Note: Service that was performed to repair damage caused by accident or misuse is not covered
under this program.
Replacement Parts
If a logic board must be replaced, order on a like-for-like basis only. The following parts are
eligible to be replaced under this repair extension program:
661-3279 Board, Logic, 1 GHz, USB 2.0
•
661-3280 Board, Logic, 1.25 GHz, USB 2.0
•
The parts listed above are the only approved logic board replacements covered under the eMac
REP for Video and Power Issues. Apple will charge service accounts for any parts ordered for
repairs involving units eligible for the eMac REP that are not related to this program and are not
covered by warranty or an extended AppleCare service agreement.
eMac Repair Extension Program for Video and Power Issues 3
Special CompTIA Code
Apple has created the following CompTIA code to use for repair on eMac (USB 2.0) computers
eligible under the eMac REP for Video and Power Issues.
Use CompTIA Code 559: eMac MLB REP when replacing a logic board under the eMac REP,
whether or not the computer is covered by warranty or an extended service agreement.
Europe
For repairs covered under the eMac REP for Video and Power Issues, IMCs in Europe must order
logic boards as stock parts using the part numbers listed above. To receive credit for the covered
logic boards, IMCs must request an RMA number from the SPS team and return the defective
parts to Apple with the RMA number.
Japan
Service providers in Japan who create a mail-in repair for eMac products eligible under the eMac
REP for Video and Power Issues should select one of the following two CompTIA codes:
Use CompTIA Code 559: eMac MLB REP for logic board repairs covered under the eMac REP
•
for Video and Power Issues.
Use CompTIA Code 558: eMac MLB REP (multiple issues) for products exhibiting the
•
symptoms listed above, but requiring repairs in addition to those covered by the eMac REP
for Video and Power Issues.
Latin America
Latin American service providers should order parts for this repair extension program in the usual
manner.

Verication and Repair
Procedure
To verify whether the eMac REP for Video and Power Issues covers the repair of an eMac (USB 2.0)
computer, do the following.
Verify that the eMac (USB 2.0) computer exhibits one or more of the following symptoms:
1.
• Scrambled or distorted video
• No video
• No power
• Intermittent system freezes or crashes
• System crashes during the startup process
Verify that the computer is eligible for the eMac REP for Video and Power Issues. Refer to the
2.
topic “Eligible Products” earlier in this chapter.
Inspect the capacitors on the logic board (highlighted below), looking for signs of bulging
3.
and/or venting.
eMac Repair Extension Program for Video and Power Issues 5
Aected capacitors have a “+” sign stamped into the top of the capacitor.
4.
Note: Not all capacitors stamped with a “+” sign are faulty, so further inspection is required
to determine whether any capacitors are faulty.
eMac Repair Extension Program for Video and Power Issues 6
Failed capacitors no longer have a at top and can be identied by signs of bulging or
5.
venting (shown below). The top may bulge upward. In severe cases, the top of the capacitor
may also show signs of electrolyte venting, which appears as a small amount of tan-colored
paste around the top of the capacitor. One or both of these signs indicate that the capacitor
has failed or will likely fail.
Warning: Use caution when handling failed electronic components, and be sure to wash
your hands afterwards.
If the logic board has bulged or vented capacitors, replace the logic board.

The RAM expansion modules used in the eMac (USB 2.0) computers are 184-pin
SDRAM DIMMs (dual inline memory modules) that are 2.5 V, unbuffered, 8-byte,
non-parity, and PC2700 compliant. The speed of the SDRAM devices must be rated
at 167 MHz (7 ns) or faster. Refer to Kbase article 86718 for more information.
Important:
specified above. DIMMs for previous models of eMac or DIMMs that use EDO or
SGRAM devices will not work. If they are installed, the computer will beep, and the
power light will flash several times when you turn on the computer. This indicates that
the computer cannot find any useable RAM.
