Question about RCA RT2250 System
Verify 120v at wall socket. Plug 2250 into mains, if not so already.
QUICKLY unplug and plug back in the unit. That should put the unit into DEMO mode, at which point you can press the (now red) power button and the unit should function nominally.

Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.
1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.
2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.
3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
