9. Troubleshooting

Work precautions

• When servicing, be sure to recreate the malfunction two or three times before starting repairs.
• When servicing, always take care to keep proper footing.
• Before starting the service, always unplug the power cord from the outlet, or turn off the earth leakage

breaker when no power cord plug is provided. Sufficient care must be taken to avoid electric shock or injury.

• Make sure to connect the power supply wires correctly.
• When removing the circuit board, always hold it at both ends and remove carefully so as not to apply force

to the surface mounted parts.

• When removing the circuit board, be careful of the metal edges on the board.
• When removing or inserting the connectors for the circuit board, hold the entire housing section. Never pull

on the lead wires.

• When circuit board failure is considered to be a cause, check closely for any broken section on the copper

foil patterns, burning or discoloration of parts.

• After replacing a circuit board, make sure to restore the same settings as before the replacement.
