I have Beolab 8000's connected to a Beosound 9000 system.  When I turn off the Beosound the left hand column speaker stays "on" - green light, and when playing sounds no sound comes from the left speakers but right speakers deliver OK.  Any ideas on if there is a simple solution?

Usual suspect is that you have switched to LINE (all the way down) - RIGHT is middle position on the switch.  This assumes you are just setting them up and that the fault hasn't happened out of the blue with the speakers previously working A OK.

This type of fault usually turns out to be a cable fault. Suggest you swap the speaker identification. ie Switch the left one to R and the right one to L

What happens now?

Hello Rex, welcome to the forum!

What you need to do now is some organized troubleshooting.

• have you checked the input switches on the speakers, perhaps the left one is now on "line" and just picks up some noise that keeps it turned on?
• swap the speaker cables at the Beosound end, does the problem move?
• swap the speaker cables at the speaker end (or swap the speakers themselves, if you have the cables built into something or otherwise difficult to relocate), what happens now?
• finally, flick the input switches on both speakers to the "other" position, ie. L to R and R to L and see if anything changes

This should give us some insight whether the problem resides in the Beosound, the cables or the speakers. It might be just a damaged powerlink cable or connector.

It's a good idea to unplug all three units from mains while altering the connections.

I am humbled by the response and now know why I have joined Beoworld and should have joined years ago!  All the advice is helpful and I will work through it after dinner.  My wife called me away and hot dinners taste better than cold ones I have found.  Fortunately I have a separate Overture system with Beolab 6000's too so I can mix and swap around to check things.  Back later and many thanks so far guys.

Amazing innit - Kingofsnakes got it straight away.  I don't recall moving them recently but maybe wide's dusting did it - the switch was fully down in the line position!!!  Thanks to all, and I hope all my problems are this easy to solve once again Many Thanks

Is it a Bullseye for Kingof Snake??!?!  Let's face it, just neeeded pointing in the right direction, if I hadn't have replied first am sure everyone else would have got it.
