If an error occurs, the STANDBY/TIMER LED will automatically begin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of STANDBY/TIMER LED flash indicators are listed here for reference. If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a [0].
* If a +B over-current is detected, stoppage of vertical deflection is detected simultaneously. The symptom that is diagnosed first by the micro-controller is displayed on the screen.
