Thank's Mika

The modul does not move a 1/100mm even using all my force

Where could I use a lever?

Would applying some heat loosen this gasket glue?

At the long side border of the modul I can see very very little white drops of some sort of hard glue.

Is this the gasket you mentioned?

Using some heat from a household hairdryer did the job !! 😁😁😁

Not an industrial heatgun !!

Thank you very much Mika.

Your tips were great! The Modul was not glued but only stuck on the old gasket.

1. I took off the gasket on the right lower corner near the modul

2. While heating with a hairdryer (not heatgun) I took away 1mm of the gasket between the modul and the tube using a sharp knife

3. Now I could get a 3.0 mm flat screwdriver into the little space I opened with the knife.

4. Still heating I pushed the screwdriver under the module half a mm after half mm.

5. I used a electro work screwdriver as the plastic isolation does less harm the aluminium when bending the screwdriver to lift the modul

6. Once it came off I saw the messy foam you talked about, there was only a little of it on the PCB ass you can see in the picture above. It was on the outer trace to the relay. I realy thought trace could not be harmed.

7. Testing the trace with the Ohm-meter , there was no contact between the starting points of the trace.

8. Cleaning it all up with some alcohol I got this view of the trace:

9. I soldered a new "trace" for each of the contacts of the relay:

10. put all together again and the speaker now works fine !!! 🤩 🤩 🤩

Well done! 🤒

It seems very common that those particular traces develop a problem. While you're in there, you should remove the old damping foam and clean the boards - and do the other speaker as well as long as it still works.

Do you replace the foam with new one?

If so, which one?

I didn't put anything in there, but I never play very loud either.

I believe you can still order new foams from B&O, if you find a dealer that agrees to do that for you. Or just cut a similar piece of some acoustically soft foam.

And don't use ESD-foam. It's conductive.
Oh yes, I have seen that ...

Do you have any Links for the right foam to use? As it appears to by possible to make fatal errors.

In the service manual I think the foam is listed as "damper", but there are no pictures of the place where they are and no picture of their original form.

Does anybody have this information?

Yes, I had the same problem.

 

Hello everyone, my very first post here.

I came to this thread by seeking out solution for exactly the same issue, one of my Beolab 8000 MK1 stopped working. It was the same trace and I rebuilt it.

I had to use the hair drier and everything worked.

While looking for the replacing foam I bumped into this eBay auction:

What do you think guys? Should I buy 2 sets?

My best
