Main Amplifier/Power Supply PCB Assembly
A solid red light indicates a system fault, usually caused by a shorted output MOSFET or a failure in the power-on-reset circuit. Replacing the entire integrated board resolves logic errors, DC offset protection triggers, and power delivery failures that the protection circuit monitors.

Internal Thermistor/Thermal Sensor
If the red light is flashing, the unit has entered a thermal protection state. This is caused by an increase in resistance in the thermistor or a breakdown of the thermal interface material between the amplifier stage and the aluminum chassis, causing the unit to misinterpret its internal operating temperature.

Replacement IEC C13 Power Cord
In rare instances, high-resistance arcing or insufficient current delivery through a damaged power cable can cause the switching power supply to oscillate, triggering a generic system fault red LED during high-demand transients.
