UPDATED: Hotpoint Microwave Display gone bonkers?
Hotpoint Over-the-range Microwave Model R VM120 001
The key pad is inoperable, and the display first was showing in small letters "N12" over the top of "DEF"; repeated unplugging came back the same, then, "0" over "COOK TEMP", then "0" over "ENTER START", etc.
