REPLACING PARTS 60
• If troubleshooting strategies (checking cables and connections, reinstalling system
software, and so forth) do not solve the problem, and you suspect that the hard disk
drive or the motherboard is faulty, always troubleshoot in the following order:
(Troubleshooting in the wrong order will cause the system to malfunction. In general, it is
highly unlikely that both the hard disk drive and the motherboard are defective; therefore,
avoid replacing both to solve one problem.)
– First, replace the hard disk drive and install system software.
Always replace a faulty hard disk drive with a new hard disk drive. Transferring a hard
disk drive from one E-43A to another is incorrect and strongly discouraged.
– If the problem persists, reinstall the original hard disk drive in the system, and then
replace the motherboard.
Motherboard cautions
If you have exhausted all other troubleshooting remedies and determined that you need to
install a new motherboard, be sure to observe the following cautions:
• Do not transfer the BIOS chip from the old motherboard onto the new motherboard.
BIOS chips are not interchangeable.
• Do not reinstall system software at this time.
Reinstalling system software is not necessary when installing a new motherboard and can
result in an error if done before transferring options to the new motherboard (described on
page 64.)
• Before you use the motherboard replacement dongle to sync the BIOS and options (for
example, Fiery Graphic Arts, Premium Edition, if applicable) from the hard disk drive to
the new motherboard, enter Service Mode (see page 64) and make sure that the new
motherboard solves the problem that you are troubleshooting.
The E-43A can remain in Service Mode indefinitely. Use Service Mode to carefully verify
the new motherboard before transferring options to the new motherboard.
Transferring options to the new motherboard permanently customizes the new
motherboard. Once customized, the motherboard cannot be returned to inventory or
installed in another E-43A. If the new motherboard does not solve the problem in Service
Mode, do not transfer options. Return the new motherboard and motherboard
replacement dongle to inventory.
• If you can verify in Service Mode that the new motherboard solves the problem that you
are troubleshooting, transfer options to the new motherboard using the motherboard
replacement dongle included with the new motherboard (see page 64).
• Do not remove the motherboard replacement dongle while transferring options to the
new motherboard.
Removing the motherboard replacement dongle prematurely will corrupt the dongle and
possibly damage the motherboard. If either become corrupted, you must contact your
authorized service/support center and order a new replacement motherboard kit.
