Try unplugging the unit for 60 minutes, then upon plugging back in, press and hold the power button at the same time for 10 seconds. This will reset the processor and hopefully the unit will operate normally. Check all the speaker wiring for shorts, make sure they're also not touching the chassis of the receiver, or are not otherwise pinched or frayed. If all looks well, try disconnecting all the speakers and cycle the power off, then on again.

If it powers up, try connecting the speakers one at a time until one of them shuts the receiver down. Check this speaker with a multi-meter and make sure it is reading between 4-8 ohms.

If not, the speaker may be blown and is causing the receiver to see a short and therefore power down.

If the unit shuts down with no speaker load connected, or fails to power up, then it likely has a bad output transistor, or capacitor and is in need of service.

I hope this is helpful to you!
