    Owner dropped it and now the volume control is very iffy.
    Before I release the panel that contains the vol control.
    Is there any very flimsy / stuck down ribbon cables to the controls or any
    other pitfalls awaiting me underneath ?

    looks as though its a rotary encoder but with end stops

    this will be fun.
    Others have got to that stage so it is presumably exposable without hickups

    Some screws hiding under flopped over electros and one under the daughter
    board that has to be released to get to that one. The LCD ribbon connector
    needs the closure pulling away 3mm from the pcb to release the ribbon.
    It is a stereo resistive volume control with 4 concentric tracks.
    Inner and next are conductive and the 2 outer 10K resistive - of the 2
    wipers , one connects tracks 1 and 4 and the other 2 and 3.
    Desoldered the 2 isolated mounting points to avoid desoldering the main 7
    pins as they are sleeve/thru soldered ,
    bending over and prizing/parting the 2 parts of the pot.
    One of the 7 pins seems to be isolated from the tracks and i cannot see what
    it would be connected to as 6 pins only are required.
    It looks as though the dropping just slightly parted the metal clasp part,
    holding the wiper and spindle, from the tracks part.
