 LE-4A Self Diagnostic Software
The identification of errors within the LE-4A 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) 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.

NOTE: IF STANDBY LED FLASHES 20 TIMES, THIS IS NOT
              A MALFUNCTION.
Symptom:
In case of no power at first switch on, the software tries to switch the
lamp on as follows:
1. Wait 20 seconds (standby LED flashes).
2. The software switches on the lamp.
3. The software checks if the lamp is on.
Yes: No problem
No: Wait 20 seconds and try again.
If necessary the software repeats the process 3 times. If after 3 times
the lamp is still off, the set goes into standby and the lamp led will
light. In this case please refer to Service Bulletin 163.
