TROUBLESHOOTING
Preface
This chapter describes how to shoot, analyze, and correct failures on the
system.
Use the Troubleshooting Hints as an aid to analyze failure. It is
recommendable to analyze the error event, environment, and peripheral
circuits during troubleshooting.
When a failure occurs on the power supply unit (PSU), the whole power
supply unit must be replaced by a new one (except a blown-fuse failure).
(The defective power supply unit must be sent back to our factory.)
r—— WARNING:
This computer uses some special parts for safety and protection.
They are marked by the international safety mark A in drawings
and replacement parts lists. Always use Matsushita's parts to
avoid unpredictable damages (X-ray exposure, electrical shock,
burning, etc.).
Note: The diagnostic program consists of several units. Diagnose each
unit successfully and efficiently by using these diagnostic
program units.
Grasp and record the failure event correctly.
Write down the condition the defective unit, and report it after
repairing the unit.
