Beolab 8000 no sound

39 replies

Good tip from Marc, had the same problem; orange light for a while, so cleaned out the foam. Light went back to red, but no sound, so checked the relay and one track was looking ropey - quick check with a meter confirmed that the track running around the edge of the board was corroded as I was getting no connection between the relay and the connector.

Quick solder of a wire and job done!

Mine had exactly the same problem. The track didn't look corroded though, but the coating of the PCB appeared to have a small scratch near the corner. Perhaps the protective laqcuer had a small imperfection from new, and that was the spot first attacked by the decaying foam.

You should hear the relay click when you plug the speaker into mains.

Hi I'm awaiting my BL8000s and one of the speakers has had this repair done already however I want to be pro active for the 2nd one and do it myself - what did you use to actually clean out the sticky mess and where can I find out to open the casing?

Thank you in advance!!

 

:)

the foam in the speakers can be vacuumed out with a hoover.

the sticky mess wil disolve in methyl alcohol, dirty job but someone's got to do it!☺☺☺

Hi IndyBoy

for the removal, take a look at may threat here: /forum/imported-unmapped/beolab-8000-amp-modul-removal-amp-repair-solved

Some help is also provided by the service manual which you can find in the download section here are 3 pictures from it:

The second picture shows 10 screws for the amp modul, but there are only 6 , 2x3 on the borders, as seen in the third picture.

My beolab 8000 is purchased in Japan and shipped to Vietnam. It uses 100vol electricity but I plugged wrongly into 220vol. now it is no sound even though the signal light is still turning green when playing music. How to fix it? please help me

tôiI want to buy

Man oh man, I am in this total fiasco.  I have a pair of 8000s that have had a B&O service center voltage conversion - 220 to 110.  They were shipped to me and wouldn't play a sound.  Both lights were orange.  Then I shipped them to a service center who "swore they were working".  Then they're mailed back to me and they're both totally dead.  Nothing.  No red light at all on either.  Nothing.  Totally dead.  The supplier who sent them originally said they worked.  Then they get to me and they dont work.  Then the repair man said they worked and they again dont work. Not even the red light!  What's going on?!?  All parties involved have been very professional, but I am getting frustrated.  Any suggestions?
