Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

the screen may be at the lowest dim setting, try turning it on, then pressing the 2nd key and then hold the up key and see if anything appears, if not let me know and I will try to figure out something else, I own a 83, 84, and 89 so it shouldn't be too hard to figure out

As battery gets drained, the screen contrast dims. But when you change batteries, some times the contrast is reset to some low value and the screen appears dead: it is so light that you do not see anything, and you think the calculator is malfunctioning. This is the most frequent reason users think the calculator refuses to turn ON. And I hope that is the case now.
To correct that, you must increase screen contrast: draken the screen a bit. To do so
