Problem with input connection on MF Vdac

When I move the digital input connector side to side, etc it connects and disconnects, also while playing. It's hard to keep it in contact. Is this a problem internally with the connector?? I heated the solder joints and it didn't work. What to do? Replace the connector??? What connector?? Thanks, Tweaker

I presume that you are moving the input connector by grasping the interconnect cable by it's connector. If so, have you tried a different digital interconnect cable?

  I did make it myself and I have yet to master soldering. I wiggled the wire slightly and did not get it to screw up , but thanks for the reminder. I'll double check the interconnect. Tweaker

    Are you using lead-free solder or leaded solder?
    You will need to leave your iron in contact with the component for longer with lead-free to ensure sufficient heat transfer to the surfaces to be soldered. A lot of people turn up the iron temperature to compensate. However, this is the opposite of what you want to do and is more likely to cause a dry joint by burning off the flux.
    In the worst cases, a dry joint doesn't bond the two surfaces together at all and you can simply pull them apart leaving a powdery solder lump. Otherwise a poor joint will cause the problems you describe - i.e an intermittent connection.
    
    The first thing to do after soldering is to check the joint integrity by pulling on the joint. A good joint should have a shiny surface with a concave surface. Don't be shy to heat up the surfaces before applying the solder - you will quickly get the timing right before you melt the components!!

      Well it was a cold solder joint. The solder I'm using has lead and is copper content solder. I will work on my technique. I did pull on it and it seemed to be solid. Cold solder joints can be tricky basterds. Thanks, Tweaker
