BEFORE YOU START: Familiarize yourself with the Macintosh SE Technical
Procedures. Be sure to follow proper ESD procedures.
Problem #1: Macintosh SE resets itself and gives ID=10 error. Also video
and sound are distorted.
Cure #1: The Macintosh SE contained a 3rd party add-on card in the expansion
slot. The card was removed and the Macintosh SE passed Macintosh SE
diagnostics. The expansion slot on the Macintosh SE logic board was not
working properly. Replace Macintosh SE main logic board and retest the
system.
Problem #2: The Macintosh SE reboots by itself, this happens even when no
applications are running and only the Finder is active. The rebooting occurs
intermittently.
Cure #2: The Hard Disk may contain an old version of system software
(4.0 or older). There may also be soft errors found when the hard drive is
tested using HD Diagnostics. Remove system and finder from the drive.
Back up the data of the hard drive. Then use HD diagnostics destructive
test to destroy the formatting of the HDA and remove all of the soft errors.
Reinitialize the HDA using the HD Setup program, install system software,
and restore the data.
If the problems still occur, refer to the Macintosh SE Technical Procedures
for more troubleshooting information.
