from the pictures, looks like a typical water damage problem, (you have flood in your area?) the LCD should be ok, but the aluminum reflector paper under the LCD glass is damaged by water,  just replace it with any aluminum foil/paper will work.  you need to clean the meter, LCD glass, and  use "deoxit" to clean the  switch, socket for the probe.

And the purchase of a good protective case wouldn't hurt either.
