Only the front speakers work none of the surround speakers
After a power surge only the front speakers work none of the surround speakers no matter what surround setting the receiver is on. I've followed the reset procedure and dis-connected and re-connected all components and speakers. The receiver was connected to a Monster surge protector. No other components were damaged.

If you are still covered by the warrenty, then you may be able to get it fixed at no cost.
Otherwise get a qualified technician (I say this to cover my but rather than suggesting that you open it up yourself) to open it up and check the fuses inside.
