Question about Audio Players & Recorders
Sounds like the output transistors are shorted. The relays are being tripped (tick tick sound) due to a major short. Need to get it to a technician familiar with receivers.

hi, when the unit shuts off by itself, it means that the protection circuity inside has been activated. it can be a problem with the receiver itself or it is just detecting something hooked up to it that can cause possible damage so it shuts off.
you would need to disconnect everything from the back and by itself, try to turn it on, see if it will stay on and then crank the volume way up to max. if it stays on, the receiver is ok and you then need to rehook your devices one by one starting with the speakers until you determine the one causing the receiver to shut off.
however, if the receiver shuts off and won't turn on even by itself, it means that the problem is internal and it either has to go back to your dealer for an exchange or it has to be sent to a repair center for servicing.
hope this helps a bit.. ^_^
