Hi and welcome to Beoworld!  This is the second BeoSound 1 fault reported today, so it's great that people are trying to get this great bit of kit working!  (I have three!) Most of my BeoSound 1 experience is in the following and linked threads:  https://forum.beoworld.org/forums/topic/beosound-1-faulty-cd-player/" target="_blank">https://forum.beoworld.org/forums/topic/beosound-1-faulty-cd-player/">https://forum.beoworld.org/forums/topic/beosound-1-faulty-cd-player/ We do have the service manual available on Beoworld for paying Silver/Gold members.  You really need to look at this before you start messing around in the service manual. Is the antenna connected in the connections underneath - maybe this could account for the lack of sound?  You could also try connecting a source to the aux socket.  Aux is selected by presing the track << and >> buttons together*. * On the later 'Mk2' model (SW2.X), aux is selected by pressing the CD < and > buttons together - just wanted to add that for completeness!

Thanks for the info. From your write-up you were at least getting a spinning disc - I'm getting nothing. I've now stripped the CD unit down, give it a light clean and re-seated cables, ribbons etc.  I haven't checked voltages yet but will do so next. I've now found the service manuals  and checked the schematics & test routines. In the error log were 0601 & 0C03. Once cleared, they haven't returned. None of the CD tests seem to do anything - straight to END. Running TM71 gives FOUL then END. I don't think a CD fault would prevent the radio & aux working and assuming I've got the pinout correct, aux doesn't work either. Nor do headphones so I suspect it might be the main board. The arial is connected and appears sound. Pr1 must have historically have been set to Radio 2 - 89.3. Interesting when scanning for FM, it skips past known good frequencies - is it supposed to stop when it detects a strong signal? With a bit of faffing I got it to 98.9 - Radio 1 - and again nothing. Thanks
