ok so i hooked up some new speaker to my sony reciever its the model number str-de635 and all the sudden it went into protection mode and now when you turn it back on there is no sound coming out of any speakers and if you turn it up all the way the sub makes very little sound... i tried resetting it and that didnt work, what can i do???? please help if you can.
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.
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.
