Hi, I replaced the transformer rubber bushings on my Beomaster 5500 to get rid of the humming issue. The humming went away but now there's a clicking noise in the speakers when turning volume up/down.
I checked the wires connected to the transformer and saw nothing wrong. Plugged it in again and then there was a very short weird very high note sound and then it wouldn't turn on. There was the red dot on the front but that was that, couldn't do anything with the remote or on the front, nothing happened.
Unpowered it again and wriggled some of the wires a tiny bit. Power on and now it works but still have the strange volume up/down noise and it have shut itself off a couple of times.
I have started looking for a replacement / backup / donor depending of the culprit causing this issue.
Any thoughts?

Also now it shuts down on it's own once in a while...
No one have any ideas?
1. Intermittent shut downs - replace idle current trimmers and readjust. Check solder joints at the amplifiers power relay.2. Different noise for different volume levels - replace capacitors in the low voltage regulator areas.

I just bought a second Beomaster 5500 which behaves exacty like the other one. All of this started after I got a Beogram 1202, I have a feeling that is the culprit. Could that be it? But then again the volume noise thing is also present when the Beogram is not connected.
I don't suppose just taking the lid of the Beomasters could cause this?
Problem solved
It turned out that I accidental bent down the clip in foto (right corner of the unit when looking from the backside). It is supposed to touch the lid for grounding. After bending it upwards no more clicks!
So don't touch that clip if you open up a Beomaster 5500 and probably also 5000, 6500 and 7000.
