Ah, like the membranes under the later BL1000's then. A bit of a shame as these are pretty much irrepairable.

ajames: Is this what being addicted to Bang and Olufsen is about?, Andrew Er... yes

joeyboygolf: I've never seen a problem with the keyboard but from the service manual it looks similar to the type used in beolink 1000 or beo4 so I could believe it could wear out with much use.
