Not really a DIY question (unless it turns out that there is in fact a
DIY fix), so apologies.

I have a bathroom scale with an LED display (branded Weight Watchers
but I don't know the actual maker) which is a good few years old now.
It's always been completely reliable but over the last couple of days
the display has refused to stabilise: it flicks up and down over a
range of about half a stone, never stopping on any one reading.

I'm assuming that it's an electronics problem rather than a mechanical
one, but am I correct?

Many thanks.

Have you tried replacing the cell/battery? I had this with the 10kg
kitchen scales and a new CR2032 cell fixed it (always check the fuel
before stripping the engine!).

When I started as a maintenance engineer (over 50 years ago), the golden
rule was "always check the power supply first", It's stood me in very good
stead over the years.
