Our lovely old stove 1980's Hotpoint stove has worked flawlessly for decades but yesterday, the digital clock and temp control screen went black.. The stovetop and oven still work but I have no idea if I can control the oven temperature anymore since the digital readout doesn't work. I don't have an oven thermometer either and
getting one right now takes effort due to the pandemic lockdown here. Before I put in the effort to order more fuses to replace potentially blown old ones, I need to know if the display is off because of a blown fuse, or is the clock / temp control beyond repair.

The first step would be to test whatever fuses there might be. You don't need a million dollar meter. A simple
automotive circuit tester would do the trick.
I wouldn't use a simple automotive circuit tester because auto is 12 volts and
the stove clock is potentially 120/240.

I think Dean meant to check the fuses when they are out of the circuit. A lot going
on here, like are fuses blowing and if so, why. If it needs a new display, poster can
find the price for one, if it's still available at all. Given the price of parts and the age,
a new stove is probably the right option.
