SONY - LCD TV_ KDL 32BX400_KDL40BX400_LED BLINKING CODES_SERVICE MODE_DISASSEMBLY PROCEDURE

LED BLINKING CODES [LED flashes]

• The identification of errors within the AZ1-N chassis is triggered in one of two ways:

1. Busy.
2. Device failure to respond  to IIC.

• In the event of one of these situations arising, the software will  first try to release the bus if busy.  Failure to do so will report with a continuous flashing LED, and then communicate with each device in turn to establish if a device is faulty.  If a device is found to be faulty the relevant device number will be displayed through LED.  The series of Flashes which must be counted.
