Hi All,

First time poster, having been a B&O owner for all of 2 weeks now.

I have bought a Beovision 7-40, with a Beolab 7.4 centre, Beolab 4000s as rears, and a pair of Beolab 8000s as front speakers.  The problem is with the 8000s.  The right speaker seems to be faulty; it remains at standby, no matter what I try.  I've tried swapping the speakers over and so have ruled out wiring problems.  With both speakers connected, they both stay at standby; if I disconnect the suspect speaker, the other one works fine.

Sometimes, the faulty speaker status light goes green, but quickly goes red again.  I presume there's some kind of inbuilt fault detection at work here that's switching the speaker off. 

This sounds pretty terminal to me.  Is there anything I can try other than replacement under warranty?

Thanks in advance,

Simon.

Hi Simon welcome to beoworld

It sounds to me like a cable fault, where the power on connection is short cut, tray and connect the the faulty speaker to the cable from the speaker thats works!

Agree with The Stig, sounds like cable fault. Try swapping things around to isolate any fault.

Hi all,

 Thanks for all your helpful replies.  It's nice to know there's such an enthusiastic and knowledgeable group of B&O fanatics!

I've tried playing with the L/R/Line switch on the faulty side.  When I set the switch to 'Line', the speaker comes on; when I then set it back to 'R', the speaker works for a couple of seconds before dropping back to standby.

I've not had a chance to swap the cables around any more (3 week old daughter taking priority!), but can anyone suggest a next step to try and isolate the fault?  I'm thinking that it's definitely a wiring problem now...

 
Regards,

 
Simon.

Well a new Power link cable will be the best solution, if this isn't a easy job. you also can look very care fully on the cable for sharp bends and marks where the cable has been pressed or stressed, cut the section out and re-connect it. but it often right at the plug the shortcut is, so cut of 5 cm and solder a new plug on mirth get it playing again..

Do you use the original sockets or were they soldered on place? When doing the installation, me an my dealer had a similar problem, and we found out that it was a socket that was faulty.

To me, it does not sound like there is something wrong with the speaker, it must be either cables or sockets.

Hi all,

Thanks again for the helpful advice.

The powerlink cable plugs were soldered on by the B&O guys.  I've had a confusing development, though...

Last night, the speakers (which were previously stuck at standby) started working again.  This sounds to me like a bad connection or solder joint somewhere, so I've asked (again!) for the B&O dealer to come and take a look.

I'll keep everyone posted...

Regards,

Simon.
