LED Blinking Summary
When an abnormality occurs in the unit, the "SOS Detect" circuit is triggered and the TV shuts down.
Shut down means that the unit turns off the TV_SUB_ON signal. The power LED on the front panel will
flash a pattern indicating the circuit area that has detected an abnormality.
