I have a marantz sr7010 and it won't start. Comes on then turns of with the power button flashing red. From what I've read on this forum it sounds like it's has gone into protection mode is something that I can do. On an old marantz post somewhere someone suggests pressing 8 buttons simultaneously does anybody have any knowledge of this with what buttons I would press on this particular receiver I have. Really hope there is a fix as not under warranty.
How frequent are the flashes?
From the 7010 manual:
Power turns off and the power indicator flashes in red approx.
every 2 seconds.
- The protection circuit has been activated due to a rise in temperature within this unit. Turn the power off, wait about an hour until this unit cools down sufficiently, and then turn the power on again.
Power turns off and the power indicator flashes in red approx.
every 0.5 seconds.
- Check the speaker connections. The protection circuit may have been activated because speaker cable core wires came in contact with each other or a core wire was disconnected from the connector and came in contact with the rear panel of this unit. After unplugging the power cord, take corrective action such as firmly re-twisting the core wire or taking care of the connector, and then reconnect the wire.
- Turn down the volume and turn on the power again.
- This unit’s amplifier circuit has failed. Unplug the power cord and contact our customer service center
If 0.5 seconds flash try either yanking all the speaker cables completely and seeing if it will power on.
Or to determine which is at fault remove one pair at a time and trying to power on each time. Sods law it will be the last ones you remove which will have the problem...

If that fails remove all cables from the AVR and try power on again.
If that fails you could try a factory reset.
