Question about Onkyo TX-DS747
Checked all wires to make sure they weren't touching anything that would cause them to have a short.
This seems to be a common problem with this model Onkyo. I have seen a lot of these, It seems like the 22volt power supply is acting up. either bad connections or capacitors. You will need the schematic and a large swear jar with tons of quarters.

SOURCE: no surround sound
So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck

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.

Have you reset the settings in the system to 5.1?Are the rest of the speakers working? Go over the wireing yourself just unplug one at a time and reseat it on both ends system end and speaker end it may just be that when he put it together again one of the wires wasn't set back just right.
