Hi Pavel,

Sorry you are having these issues. I suggest you send it back to Bresser Germany. I assume you bought if from them. They should be able to test the mount and fix it for you.

Yes, I am in contact with them. Just wanted to avoid unneccesary trouble caused by some trivial issue, such as bad contact in the power adapter connector (but I suppose the red LED would not turn on at all). Maybe it would be enough to send just the bare controller instead of the huge and heavy package - but I will arrange it somehow with them.


Hi Pavel,

I have the same issue. Were you able to fix it or did you send the mount to repair?
