Your receiver uses power modules (STK0029). One is bad. I recommend checking all components that are connected to any pins on the bad module.
I'm not sure if this module is still available; you can check eBay.

Found a pair on ebay for 35.oo. Is that a good price? About checking the components connecting to these power modules; with a continuity tester or something else? Kind of green at this. Thanks for the help!

Use an ohmmeter to check resistors and diodes. If you are not familiar with test equipment, you should look for any burned resistors; if you find one or more then maybe a tech should look over your amplifier. With any luck just the module is bad. Most bad diodes won't look bad, but they can short or open.
Check your speaker cables for shorts or frays, as this can cause the modules to go bad.
