    A repair job for next week, UK made in last year or 2
    Detects presence of metal but a very broken audio output
    like a bad contact but nothing found by prodding.
    All surface mount devices. There would appear to
    be a negative voltage generator on the board somewhere
    that may be wavering.
    Anyone recognise this
    Texas Instrument (tiny indistinct logo so maybe not TI )
    8 pin SM IC numbers on it
    The other ICs I can probably identify

    electronic hints and repair briefs
