Laser Scout , Metal detector
A repair job for next week, UK made in last year or 2
300 GBP machine so worth repairing. 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 22621 18T A72J The other ICs I can probably identify electronic hints and repair briefs http://homepages.tcp.co.uk/~diverse |
