AE-6B SELF DIAGNOSTIC SOFTWARE

The identification of errors within the AE-6B chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In theevent 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 continuousflashing 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 relevantdevice number will be displayed through the LED (Series of flashes which must be counted) See table 1., non fatal errors are reported using thismethod.Each time the software detects an error it is stored within the NVM. See Table 2.

Table 1 How to enter into Table 2

1. Turn on the main power switch of the TV set.2. Program Remote Commander for Operation in Service

Mode. [See Page 20].2. Press ‘VIDEO’ ‘VIDEO’ > ‘MENU’ > ERROR MENU

on the Remote Commander.3. The following table will be displayed indicating the error

count.

Table 2

Note: To clear the error count data press ‘80’ on the Remote commander.
