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. See Table 2. Table 1 LED Code 00 01 02 03 04 05 06 07 08 09 10 11 How to enter into Table 2 1. Turn on the main power switch of the TV set and enter into the `Stanby Mode'. Press the following sequence of buttons on the Remote Commander.
