How to open up a BEOLAB 4000?

6 replies

I have a problem. Owns two Beolab 4000, MK II, speakers and I need to change the amplifier board in one of them. I can remove the black speaker grille but after that I dont know how to proceed. Tried to find info on the Web but did not find any  useful information... What is the next step to be able to open the speakers?

Best Regards

Hi

Having removed the grill, remove the 2 torx screws you can see which allows you to remove the metal shaped profile. This will reveal about a dozen more torx screws. Remove them, and you'll be in!

Cheers

Hi again..

I´m sorry but I don´t  manage to remove the metal shaped profile. Seems impossible.

Dont know how much force to apply?

Any more tips or tricks?

Something is perhaps not correct.

I have 3x TX10 holding the profile?

Can not remove the profile after removing these 3 screws.. What to do?

lift few mm alu profile at the end whre t screws are ... and than slide the oposite way from the screws the alu profile.

that is it...

One more question..

Need to know where to buy PCB03 for the BEOLAB 4000?

Is it possible to  obtain one for a resoneble price? Used? Old inventory?

Best Regards
