AE-6D SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6D
chassis is triggered in one of two ways :- 1: Busy or 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 the LED (Series of flashes which must be counted).

Model Setting
The menu contains a list with all the
available models of this software to set up the TV set in an easy way. The
selection of a model is setting data for its features and hardware resources
which cannot be detected by the automatic power on H/W detection as well as a
special model byte to get an unique model identification for models
which cannot be differed by features and hardware resources (e.g. KD-32DX100U
and KD-32NX100U). Before data is set, the user will be asked if he really wants
to set a new model. If the user agrees, the destination setting menu is
automatically shown.
