Your audio output transistors are shorted and your unit is staying in "protect " mode to protect your speakers from 40 to 60 volts that is being sent at them from the shorted outputs. If you can use a meter you won't need the schematic MOST likely because the outputs are USUALLY the only parts that short out. The output transistors( or chip ) are mounted to the large, finned heatsink. The #'s on the transistors start with "2SA-" and "2SC-" followed by numbers. There are two output transistors per channel. If your unit uses an IC for audio output then the # on the IC will be "STK-" followed by numbers. These parts are available from tritronicsinc.com. Good Luck!

If the unit is like the Rx-570 , the display bulbs have quit.
Theyre 14 volt lamps about 0.1 wide x 0.250 long (white wire leads)
Located in the plastic shroud behind the display

Disconnect the speakers and try it again. Come back with results. It's trying to tell you there's a short on a speaker output.
