ERROR CODES

The identification of errors within the AT2X 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).

If you do not have a remote control to unlock the TV, you can follow this method.  In some models, there will be a backup battery [Lithium type], to hold the memory.  If your TV has such a backup battery on its mains system control section, unplug the TV from AC mains socket, open the TV, take out the battery.  Wait for one hour or so, and reinsert the battery.  This must clear the memory.  All the data in memory will be lost.  You have to set all once again.
