Hi all, hoping someone can help.

Woke up this morning to find one of our Beolab 1's turned on (green light) with a kind of 'rustling static' noise coming out of it. 

It makes this noise whether or not there is a source connected to it, and at any setting (L/R/LINE, freestanding/near wall/etc).

Took the grill cover off and the static appears to be coming out of every woofers/tweeter.

Has anyone experienced this before? Any ideas what to do?

Any help appreciated - we love these speakers and want to keep them going as long as possible.

More clues!

It'll still play music OK, just with this rustling noise as well.

The local B&O shop estimates A$1300 to ship the board back to Denmark for repair, which hurts - this has to be a component failure!

Any help appreciated.

I though I'd provide an update for anyone interested - the speaker was fixed easily in the end.

The culprit was one bad capacitor. A few were replaced, and now side-by-side with the second speaker in the pair this one's sonically much nicer.

Proves was Beolab 1's are old enough to justify recapping!

Hope it helps someone.

My pleasure. 

I'd add the difference against the other speaker in the pair (that has no faults per se) is really, really audible. Enough to justify recapping the PCBs - something I might look into shortly.

I run mine off the line-in out of a very-much-revealing DAC/preamp, and the net results is much nicer. There's life in these speakers yet :)
