I second the replace the batteries ;-))

But remove the battery overnight too with the battery terminal shorted and 
the meter on...  Sometimes that will clear CMOS confusion if it is just soft.

If that and new batteries don't help, at least the leads are probably fine ;-p

Those tiny little submicron transistors and stuff just don't like giant 
induced currents and 100kV+ E-fields...  I have cooked a few meters too and 
they are just scrap plastic...  Sorry bout that...

Cheers,
