TROUBLESHOOTING
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) at each service station. (The defective power supply unit must
be sent back to our factory.)
When replacing blown fuses on both @) AC input (primary side) and (2) DC
output (secondary side) of the power supply unit, be sure to use
Matsushita's genuine spare fuses.
