The meter circuitry seems to be the weak point of the KX: I've been 
through several with dead meters.

I never completed troubleshooting to 100% certainty, but it seems very 
likely that the culprit is the integrated circuit that comprises the 
most of the meter electronics. I never determined exactly what the chip 
is but it's an 8-pin SOIC and most likely is a dual op-amp or 
comparator, so if you could determine the pinout, finding a suitable 
replacement shouldn't be too difficult (though soldering it onto the 
flexible "circuit board" might be another story).

No, I don't have a schematic diagram :(
