SERVICE MODE
This is the diagnostics to locate the faulty position.
The diagnostics can be executed using the remote commander (Remote Control Mode1) and a monitor.
To execute the diagnostics mode, connect the VIDEO OUT (L2 OUT) connector to a monitor. While pressing INPUT SELECT, REC
MODE and STOP of the main unit, connect the AC power cord to the power outlet to start the diagnostics.
Keep pressing INPUT SELECT, REC MODE and STOP of the main unit (about 10 seconds) until the diagnostics screen appears on monitor
display.
Either “OK” or “NG” appears on the monitor screen while the diagnostics is in progress. You can judge the respective device or its
peripheral from the message of either “OK” or “NG” on the monitor screen.
When an abnormality is detected, the diagnostics is stopped at that moment and you can select to proceed the diagnostics or to stop it.
Use the remote commander (DVD1) keys or the keys on the front panel of the main unit to operate the diagnostics.
