A friend of mine gave me a Yamaha R-V905 that was broken. It will power up however it is stuck in DVD/LD as an input. I tried running audio through that input however - nothing. Trying any controls on the front panel provide no response. I am fairly good at electronics and board work. However - I have really never delt with this type of unit.
I have opened the lid and it was very nice to see that this is a pretty modular type of unit.
I know that this is a pretty broad question - what could be wrong? Any help would be great!
Thanks!
