TC-L37DT30 Power LED Diagnostic Codes
When an abnormality is detected, the protection circuit resets the unit to the standby mode.
The (A) board microprocessor causes the power LED to blink a number of times. The number
of blinks points to the circuit where the abnormality is detected.
Protection circuits are incorporated in the unit to prevent the failure of a single circuit or
component from creating catastrophic damage. A shutdown condition occurs when a there is
an over voltage, a short or a drop in any of the voltage lines.
