Andy,

> In simple terms the impedance meter isn't working.

Check the diodes in the impedance bridge. These are quite easy to fry. A 
quite modest discharge of static into the antenna terminal is enough to 
end their life as semiconductors, and turn them magically into conductors!

> Is this fixable?

Most likely yes. The impedance meter circuit is quite simple.
