Question about Yamaha DSP-A1 Receiver
Either the power switch is shorting out, or you could have a faulty or somewhat faulty resistor or capacitor on the power board. You can test them with an anlalog meter. Each component has an imprinted number on it to determine it voltage and ohm rating. That number should match the number on your tester.
Some units also have relays in them. The little square plastic boxes. You can test these with an ohmmeter but you would likely have to pull the circuit board to test the relay from the solder joints on the bottom.
