Yamaha RX-V470 - Center channel repair

[Pfann4]

As I was remodeling a room, I experienced a fluke accident. My center speaker wire (the end that was is usually connected to the speaker) accidently touched an open electical outlet and zapped my center channel. Is this something I can repair or have repaired? I realize my receiver is over 10 years old, but it works fine for my needs.

Thanks
