Re: Sony xbr55x850d & 7 Blinks

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402. Intermittent problems ?? This is a great feature. You can also bring up these fault codes ON-SCREEN to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred....
