Hi all again,

does anybody know what problem would give this sound in one of my Beolab 5 speakers could be? (problem only in 1 speaker; checked all cables, also after switching role from "left" to "right" problem stayed at that speaker). I uploaded to sound clips in my dropbox public folder:

If there is no signal: putting on the speaker gives a brief sound, then silence for about 10 seconds and then, coming from below, a rattling/humming sound constantly

so first file starts with speaker on (noise is there); @13 seconds: speaker off; @21 seconds: speaker on (brief noise), silent till 31 then noise again

https://www.dropbox.com/sh/fjb89oko6wywum7/AAAr_XAiwbH3QwqxG3gbHj2La?dl=0

second file: how it sounds when TV is on (dutch news)

Thanks in advance, Rene

Het is op zich een bekend geluid. Lijkt op die in een BL4(000 mk2). Sluiting in een versterker en dan de voeding niet op gang wil komen.

Dat geratel en gehum duidt vrijwel zeker op een defekte ICE power voor het (sub)laag.
