I have a BeoLab 6000 that functions perfectly without the front cover. It switches ON when music is played and switches OFF again when music stops.
When it is OFF, and I put the frontcover in place, it immediately switches ON. I then can also hear a rumbling noise. And the speaker does not switch OFF anymore (to be clear, also without music). The rumbling noise stops when I remove the frontcover, and the speaker also switches OFF again.
I have tried putting on two different frontcovers from two other BeoLab's 6000, but it did not make any difference.
Anyone who has a clue what is going on, and what can be done to solve it?
Hi
How is your Beolab connected? RCA IN or Powerlink IN?
Kind regards
Christian
Hi Christian,
It already happens without connections.
Could this be caused by bad RCA or PowerLink connections?
Seems that you are connected to RCA right?
As I remember there was a workaround for that kind of speaker depending on the serial number. Two parts have to be soldered into the main PCB ( one diode and one resistor i think)
If the speaker is set to RCA input a little 50 Hz hum or another distubing noise, prehaps catched from your frontcover, could trigger the power on.
If it´s set to Powerlink (L or R) the speaker should stay off, if no Beomaster or Beocenter is connected or if a connected device is switched off.
Try to push the switch often back and force to eliminate corosion of the switch inside, maybe it helps a little bit, if the issue changes seems that the swicht is the one to inspect.
Thnx Spassmaker!
It already happens without any physical connection to RCA or PL.But it is clear that the front cover is triggering something.
Do you have more info about the workaround? Which diode and resistor are needed, and where do they have to be soldered?(I will try with the switch)
Check +8,6V and -8,6V
Desolder IC1 - autostart off
Thnx Jack.
What do you mean by ‘desoldering IC1’?
Removing it physically?
Sorry but I don´t have further information to the modification. I read it somewhere long time ago and could´nt find it.back.
Desoldering (removing) IC 1 means that you dont´t have the autostart funktion via RCA anymore.
I used to have it broken and it kept waking up. Solder out for test.
