My Pioneer VSX-406 has been in storage for three years. We recently powered up the unit which appeared to be starting up normally, but then the indication on the front panel read "POWEROFF" and there is no output from the unit. We can still scan the radio bands, and there is electrical output from the 110 volt jack on the back of the receiver. There is no sound output, and each time we select a function we get the same "POWEROFF" indication. I've checked to see if there is a battery inside that might be depleted and found none. The fuse on the circuit board checks out okay. I have downloaded the schematic and repair manual, but found no solution in that information. What should I try next?
Have you tried the owners manual (not the repair manual)? It will probably have something about this. It may be that this is the generic message that the unit gives you when you have a bad output channel which would put it into a protection mode.

Thanks Duncan. I agree that it may be a protector circuit function, but there is nothing in the user manual regarding this.
