Our Salter Bathroom Scales stopped working. I fitted new batteries and it was still dead so I opened it up to do some basic checks (not wet, power getting to circuit etc).
A component had come off the edge of the circuit board. I thought it was a piezo sounder device - disc shaped thin brass, about 1/2 inch dia.- wire to centre - soldered on the edge.
I thought it a bit odd as I had never heard a sound from the scales but I soldered it back on. Behold - they worked. Still no sound so I am wondering what the componenet might have been. Any suggestions.
I suppose I could take it appart and take a photo.......(SWMBO has mad me put my tools away!)
