Does anyone know where to access parts for Yamaha RX-V1?

My right channel went out. My tech said it was the Dolby processer board. I found someone parting one out on eBay, but he never indicated he had that part. I hate to scrap it, but without one of the front channels working, it's just a doorstop.

 

Bump. It's been a year since this thing was working. Unfortunately, I simply can't afford a new amp. There are three of these on e-bay right now. One has the exact same problem as this one, one may be good for parts, as it's been dropped but is functioning.

Would it be worth buying the parts amp for $250 and then paying another couple hundred to transplant the processor? I'd hate to through good money after bad, but I also can't see me ever being able to afford this level of equipment again, at least not in the foreseeable future.
