Wow, i have the exact same five speaker setup and the exact same problem.

I am tired of dealing with it all the time with disconnecting and reconnecting the cables and the mains every month or so as it reoccurs.

And i have one more sympthom of this problem: the led on the lab5 which is on the left flashes green instead of lighting up solidly when in use...

If you have a BS3 - or BV7, BV9 incl. a BS3 - in your setup check the SW and update.

Do you have sound from your left BL5? Red in standby mode?

Calbration on your left BL5 works?

Change left - right via switch on the back of the BL5s - same fault?

Stefan:  thank you for your post.  My menu has white lettering on a black background.  The Monitor Information screen says "06 IC3  AP SW8.12a,  06 IC2  IOP SW23.00a", so I assume my BS3 SW version is 8.12a. 

The dealer did say there's been quite a few updates issued since mine was updated.  I trust it will be updated to the current version when the tech comes by.

Dave, please keep us posted!

Hi just an update:  the tech came yesterday to update the software on both the BS3 & the BL5s.  Problem still there.  He used his own cables and he checked the voltages of the pins but for 3 hours of setting/resetting couldn't get the BS3 & BL5s to talk to each other.

At least now we have narrowed the possibilities.  He's suspecting the BS3.  He would be consulting B&O and would return with another BS3 to try out.  I'm hoping it's the BS3 that is the problem instead of the BL5s, as the BS3 is more transportable.  Hate to think of transporting the BL5s to the shop for diagnosis/repairs.  Will report progress when the tech returns.

Just an update & hope this solves the pr oblem:  after much back & forth testing the tech discovered that the soldered pin connections to the BL 3s & the 7-2 center speakers have a short.  The pins 2 & 7 were either interchanged or were touching.  The BL 3s and the 7-2 seemed to operate normally all this time but the tech said this interfered with the data transfer to the BL5s.  Anyways he re-did the connections and so far the BL5s are back in operation.

The original testing didn't pick up this fault, according to the tech, as these other connections were not removed during the testing of the BL5s.  The BL5s came to life after we've removed the other speakers' connections & reset the BS3.  That was the final clue that led to the discovery of the cabling issues of the other speakers.

Thank you for the advices given here that helped to provide great insight.
