LED BLINKING CODES_SELF DIAGNOSTIC DETAILS_SONY KV32FQ70 - FD TRINITRON TV


SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6B chassis is triggered in one of two ways :-
  • Busy.
  • 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 the LED (Series of flashes which must be counted) See table 1, non fatal errors are reported using this method.
Each time the software detects an error it is stored within the NVM.
Flash Timing Example: e.g. error number 3.
