I am a little confused here. Based on your earlier thread link I though that the issue was that the Beolink Passive was allways on, but now it sound like you can not get it to turn on after all. Am I misunderstanding something?
first with powerlink cableAre you using af fully wired MK2 Powerlink cable? The Beolink passive is activated by 5V on pin 1 in the Powerlink cable and only the fully wired MK2 Powerlink cable has this as mentioned by Guy in this post in your earlier thread

sorry the passive is on all the time can not turn it off , it is the ic 305 that is controling the input from powerlink or masterlink , that is
stopping the signal. or it is mutedet . when i connect powerlink MK2 , there is 12v on pin 1. i connecede masterlink to see if there whas
any differens.

Ok I see. I might be worth to look if the mute signal from the Microcomputer changes when the Powerlink pin 1 is active (12V) and inactive (0V), and if it goes all the way to pin 9 on IC305

there is no change with or without powerlink . pushing the small off button and p 200 pin 1 goes low
but there is no change at st.by out from microcomputer p 200 pin 14.
