I rewired the output cable from 4000 to 6000 directly, and there was sound, so the Beolab 2 is no longer receiving any signal. I tried different cables but this did not help either.
Any advice on what I can do or how I can test for issues? I do have another spare Beolab 2 that doesn't fully work (but I believe various components within may still work), which I can use for donor parts, but would be great if I can get some advice on which parts or how I should go about for testing.
Thanks!
