Hi,

 

I have a Beogram 3000 turntable connected to a Beomaster 3000, it has the original 7-pin data link cable that has worked properly for years.

 

But now it seems like there is a play in the cable and the sound gets laggy/faints.

If a fiddle a bit with the cable where it connects to Phono input on the Beomaster it makes it better/worse.

 

Could I troubleshoot this somehow? How easy is it to replace the cable?

It sounds as if the phono plug has a bad/dry joint.
I would open up the 7 pin DIN from the BeoGram, and check the  soldered connections.
I have found that if I warm up the plastic sleeve on the plug, that it can be slowly pulled back to give you a better idea.  Otherwise, I suggest getting a new 7-pin DIN and cutting the sleeve off, make a note of which wire is on which pin, then simply replace the plug with the new one. (Remembering to slide the sleeve onto the cable first - been there and made that error in the past !)
Hope this helps - Graham

Thank you @gravity-graham this is how the wire looks, I have no idea how they should look? Is there a scheme you can see somewhere?

There is a blue cable that is not connected to anything and it looks to be at least 2 pols that is not connected, could this be the problem?
