Your having audio issues? Maybe the troubleshooting flowchart is the solution.

Hi Folks,
I have an issue with the Right channel (no sound) RT-909, after all the troubleshooting still no sound on that channel. Is it possible a fuse is the cause?

You might want to start a new thread- you'll likely get more responses if it isn't buried in here.
 
I have a Yamaha Pre Amp C-45 that needs to be repaired.Someone have a block diagram for I to try repair it?please send it when anyone come to know.
 
But I agree, these kind of charts really help. You never know which minor mistake is the cause for anything not functioning.
 
Found something interesting out. That routing all my inputs through my Sony stereo preamplifier 2000 then to to the cd input of my marantz av 600 dolby thx premplifier makes everything sound incredible!
