    Being that the protection light is on, you may have a shorted power amp output section.

    Be aware that this is not a simple unit.

    The power supply is of the switch mode type.
    Microcontroller monitored at that.

    The power amplifier is of the Class D configuration.

    If you are real experienced at this type of equipment, I would suggest that you try to come up with a schematic.

    If not, take it to someone that is.
