This may sound silly but are you 100% sure you are plugging the turntable into the correct socket? There are numerous inputs on the BM5000 & it is easy to get it wrong - it has happened many times before to Beoworld members.

FYI - the phono input socket is the very bottom right hand one when looking directly from behind & it is very tight to plug into.

Chris.

Something else doesn't seem right.  He says he gets perfect sound when hooking up a CD player to the phono inputs.  Shouldn't this come out blasting?  Perhaps the internal phono preamp is faulty.

It's plugged in there.  I tried it in the one above (aux/cd) just for fun and got nothing.

OK.  I've now aquired a correct antenna and speaker wires for my beosystem 5000.  Also have MCP 5000.  I have the beogram 5000 plugged into the correct DIN receptacle.  I haven't hooked up either beocord 5000, because they both smoke from the left rear when I turn them on.  I'll check into them later.

Everything seems to be in working order, except there is very low output.  Radio stations come in clear, but very low.  Same with the turntable (which has a good MMC3), clear as a bell, but low volume.  Here's the kicker:  When I plug my Denon CD player into "line in" with the RCA jacks, it sounds great.  It doesn't respond to the MCP, but I assume that is because of the RCA connections, instead of the 7 pin DIN.  Here's the other kicker:  The CD player not only works when system is in "aux/cd" mode, but also if you you switch the beomaster 5000 to "phono", "tape 1" and "tape 2", with a slight lag for switching functions.

Any ideas?

I think I got it.

You mention connecting your CD-player to the RCA line in jacks. The problem is that those connectors are NOT meant to be used that way!

Between the "line in" and "line out" RCA sockets should be two metallic forks connecting them (ie. left line out -> left line in),

Thanks, lausvi. 

I don't have the jumper forks between my "line in" and "line out RCA's.  The picture really helps.  I've seen jumpers like that on old tube amps, Fishers and Scotts and the like.

Are you saying that with those jumped my output should be normal?

Without the jumpers there should be no sound at all from the speaker outputs (and from the headphone output as that's just a copy of the speaker output with a limiting resistors). Without the jumpers (line ins not connected) the output amp is not getting anything in, but perhaps in about max. volume the crosstalk is enough for some sound to make it through.

Jumpers are the neatest option but just an ordinary 2xRCA male - 2xRCA male cable will do. Left/right outs to left/right ins and it should work normally.

Thank you.  RCA's in place and it is sounding great.  I'll get a DIN adapter for the CD player, or, better yet a CD50 to complete the system.  And, of course some S55's or RL60's to replace the old KLH model 17's I'm playing through now.

Any thoughts on why my beocord 5000's are smoking (I have two, one with a tape stuck in it)?  It seems I remember seeing something on this forum or somewhere else saying that (smoking) was a common problem with them.

Glad you fixed the jumper problem - I have one of my BM 5000s wired with simple RCA cables,  the others have the jumpers as shown in the photo.  The purpose of this setup, is to be able to interface an equaliser between the pre-amp and the power-amp should you want one (and no, there was not a 5000 equaliser made by B&O).

There are control signals sent on the DIN cable as part of a protocol called DATALINK; I doubt that the Denon will respond to those.

The CD50 of course does respond to these commands, including skimming for track selection (or exclusion); however CD50s do age.

I think you may have to disassemble the Beocords to see what has happened.  You will find lots of instructions and photos on how to do that in old forum threads.
