If you connected speakers with an impedance rating other than 8 ohms or higher to that receiver, you may have put it on protection mode permanently. This can also be caused by speaker wires being crossed. Check the connections and reset.

What was the impedance rating of the speakers that you used?

Unfortunately by doing what you did, you have damaged your Sony receiver. That unit is not designed to handle low impedances.

time to shop for a new unit.

Hopefully the replacement of the fuses will solve your problem. Others have not been so lucky. Just make sure that you replace them with the same value.

Good luck.
