TI-83 Has Black Spots When I Type Anything, How Can I Fix This?


battery backup
Dan asked:


Whenever I type anything on my calculator everything just turns a glitchy random black
I tried the reset trick (2nd “+” etc)
it does nothing
I tried changing the AAA batteries which also did nothing
I took out the backup battery though I did not change it but that still did nothing
Any suggestions?
