Are There any Yamaha AV Electronics Techs

Hello, I am having a very specific problem with a HTR-5990 AV receiver.

I have no sound output from analog or digital sources. Only when I connect to the 6ch multi input can I get perfect sound. This means the amp section is good.
When I am in the service mode and I am checking the dsp field I have
TI BUS:BOOT
and
YSS BUS: WAIT

is there anyone out there with experience with the htrs or a direction I could be sent. I tried yamaha and they chuckled and said there was no way they would let me speak to a tech nor would they give me a number to reach one. I have tried two authorized service centers but they just want me to bring it in for the diagnostics fee. I just dont want to start throwing boards at this beast I want to attempt a proper repair. Thanks for any consideration in this matter.
