Keep and fix or junk?

I just picked up a wonky Sony str-de695 speaker reciever subwoofer combo on Craigslist.
I was advised that the front R/L channels were "low" and after assembling and testing, the rear L surround channel is also low.
After a factory reset, these three channels play at about 10% of other channels while playing the test tone in setup mode.
The front channels do not offer the +/- 10db adjustments available to the surround channels. However, in pure stereo mode, with the amp volume cranked, the audio quality is just fine.
I am puzzled. I am pretty sure I have exhausted programmatic resets, but if reseating a board or a connection might help, I am game.
If the end result is simply that the amp is toast, that's fine. The sub and speaker set was fairly priced without the amp.
Can the amp be repaired, or is it dead?
What can cause a channel to drop so dramatically in volume without affecting quality?
