SELF DIAGNOSIS FUNCTION
When turning on the TV, a self diagnosis function is executed.
If no acknowledgement is returned from a device which is turned "ON", the device has a problem.
In this case, one of the LED's responding to the problem device will flicker a defined number of times.
The flickering frequency responding to each failed device is shown below.
