Beosound Ouverture doors not closing at all. Solved. After PCB9 replacement.

[Jan]

Hi,
I’m having a problem with a Beosound Ouverture. I’ve made several of them. This one has a problem: the doors open immediately, but won’t close at all. I’ve removed the glass doors and the side panels. I’ve replaced the door strap with a proper one from Danish sound parts
They keep sticking open. After 15 seconds, they go into standby mode, but the doors stay open. By turning the weel at the back I can close it until the switch is closed. Moving my hand in front doors open direct and smootly.
Does anyone have any suggestions for solving this problem? I have searched this forum and the older ones and I can’t find the solution how to fix this.
Groet, Jan.

Solved.
While posting the problem. I suddenly realized after looking at the service manual that PCB9 controls the motor and the doors.
I replaced PCB9 with one from another Beosound Ouverture (which I still have for parts), and now the doors open and close properly again. L2722 on the old PCB9 was somewhat black and probably burned out.
Now I just need to replace the belts on the cassette deck and hope to get the Beosound back together properly, because that plastic breaks down after all these years. This one can get a second life for someone who loves it.
Groet, Jan.
