I have a pioneer VSX-522 tuner with a basic 5 point system.

The system worked great for a year and a half. Then my wife moved the furniture around including the tuner and speakers, but didn't unplug anything but the power cable.

Shortly after it was moved, kids were watching TV and the tuner shut down pretty quickly. They turned it back on and it shut down again. They turned it on a 3rd time, it shut down again and never turned back on.

I unplugged all the speakers and moved it to a different outlet. Still it won't turn on.

I opened it up and tested the fuse that is on the panel that the power cable goes into. The fuse is fine.

Any suggestions other than buying a new one which is a horrible expense during the holidays? Thanks!

If you turn the unit on and it shutsdown automatically it typically is detecting a power supply issue and shutting down in protection mode. Other than maybe a possible item that dropped into the cooling vents and is causing a short I would say the unit will need replaced. The only other suggestion would be to leave it unplugged for an extended peroid of time before retrying.
