Hello, My beloved Beosystem 2500 has suddenly stopped outputing via Powerlink. I had it connected to a BL converter and was playing through some Beovox, working fine. However today I took delivery of a fab pair of BL2500s but they won't play. Red lights on Beolabs come on. Red light on Beosystem comes on. Beosystem plays cds, radio, tape - but Beolabs don't click on to green and remain silent on red. I connected the Beolabs up to a Beovision in the kitchen and sure enough they go green and play sound. I'm baffled. I connected a pair of Beolab 6000 to the Beosystem 2500 with a Powerlink mk3 cable and it won't activate them either. Do Powerlink sockets "go off"? Do they die? Can anyone think what might be the reason why the sockets no longer seem to work?
