Hi Martin, Got it working, no I did not open it or anything, I am not a tech. I unplugged the 7 pin audio cable from the receiver. Played a tape, then I touched FF, guess what it did. Then I tried REW and it does it.
I reconnected with Beomaster 5000 and tried it with MCP 5000 so far it is responding to all commands.
Not sure what was wrong but so far it seems to be working ok.
What do you think happened here?
