Troubleshooting

WARNING: Only authorized technicians trained by HP should repair 
this equipment. All troubleshooting and repair procedures are detailed 
to allow only subassembly-/module-level repair. Because of the 
complexity of the individual boards and subassemblies, do not attempt 
to make repairs at the component level or modifications to any printed 
wiring board. Improper repairs can create a safety hazard. Any 
indication of component replacement or printed wiring board 
modification may void any warranty or exchange allowances.
