Technical Aux audio socket blue and me

[Harvie]

Usb not working due to previous Blue and me problem . Repaired by Revtronic Bradford, excellent service , worked for 6 months but went down again a couple weeks ago. Revtronic bench tested it and its fine. Refitted, no joy. Fuse is ok, power to 16th pin in plug but no power to no 1 pin. Been suggested that box itself needs changed

Now the audio jack is playing up

which i connect my phone to for audio books. Very slack so is it just a case of puling out and connecting a new one.
Not taken out yet, but what kind of connection is underneath?
Thanks in advance
