SONY TRINITRON - KV-32HS500_KV32HV600_ BLINKING CODES _ SELF DIAGNOSIS
[DA-4 CHASSIS]
APPLICABLE TO: SONY TRINITRON - HS_HV_DRC & XBR SERIES MODELS
When an error occurs, the Standby/Timer LED flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas.
Results for all the following diagnostic items are displayed on screen. If the screen displays a [0] an error has occurred.
# If +B over current is detected, stoppage of the vertical deflection is detected simultaneously. The symptom that is diagnosed first by the micro-controller is displayed on the screen.
## If Standby/Stereo LED flashes (6) times, unplug the unit and wait 10 seconds before performing {G2} voltage adjustment.
