This
Service Maintenance Manual
is a troubleshooting guide that can be used for
reference when servicing DIGITAL PC 3500/5510 computers.
DIGITAL reserves the right to make changes to this
Service Maintenance Manual
without notice. Accordingly, the illustrations and procedures in this document might
not apply to all DIGITAL PC 3500/5510 computers to be serviced since many of the
diagnostic tests are designed to test more than one product.
CAUTION:
DIGITAL recommends that only A+ certified
engineers attempt to repair this equipment. All
troubleshooting and repair procedures are detailed to support
subassembly/module level exchange. Because of the
complexity of the individual boards and subassemblies, no
one should attempt to make repairs at the component level or
make modifications to any printed circuit board. Improper
repairs can create a safety hazard. Any indications of
component replacement or circuit board modifications might
void any warranty or exchange allowances.
