Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

its a power failure inside the ps3!!! You have to call sony to replace the system it will cost u 150.00 dollars unless ur still under warrenty goodluck because i had to get 3 systems from sony before i got one that worked just right

this is meant to happen if u turn the ps3 off it flashes for about 10 seconds and stays on standby with the redlight
