Question about Audio Players & Recorders
Most likely what you did was burn out the output transistors to the center channel. and probably the Bias resistors that control them. The parts themselves would be inexpensive. But they would probably have to come straight from Onkyo. And you would have to know there part number. And to get matched complimentaries. Mark up. And how far into the circuit the damage went. If I was to repair it I would probably put $100 to $125. But depending on the age of the unit and what a new won would cost is what I would use to decide to replace or restore.

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

I got the same problem and on my AVR1404 it is the regulator
-15v (7915). You can control voltage on
R145 : +15v and
R146 : -15v.
The other side of these two resistances are joined together.

I am also having a similar problem. I am using a classic 1985-87?? reciever. I dont want to give it up however, i blew a fuse after plugging in an input while the unit was turned on. The system light up and that was that. After replacing the required fuse correctly, everything turns back on. No sound output. no indication of sound off the needles either..

The unit is in what is commonly known as "protect" mode. This means that a problem has been detected in the final output stage of the amp and the outputs are shutdown to prevent further damage to either the receiver or speakers. This should not be a difficult repair for a service shop. Expect a parts cost in the $25-$40 range. Add in the local labor rate for the total repair cost.
