Options besides taking it to a repair shop are probably limited. Are you
technically competent? Can you use a multimeter, have some basic knowledge
of electronics and are able to solder in the necessary new parts? The most
likely thing is a "blown amp channel" but anything seriously shorted will
blow the fuse, such as a shorted filter capacitor or bridge rectifier. Onkyo
may not have the service manual anymore, but an authorized Onkyo servicer
can download the PDF.
