I've had a similar problem in the past. With mine though it was white lines. It still happens sometimes when I don't use it for a while. To fix it, all I did was set the screen to its darkest setting and left it on for 10 minutes (keep it from turning itself off, by pushing buttons ever few minutes.) It works great, and the calculator is fine unless you leave it unused for a month or so. A similar solution may work for you.

ok guys, after about 10 years of not using my ti-83, i put the new batteries in and got the black screen you are all talking about.. came to this site.. saw no solutions.. kept looking.
I've fixed my calculator, but my brain won't tell me exactly how.. but i followed those instructions..
you CAN see what is on your screen if you tilt it under the light ... just fiddle around until you can see faint writing on your screen under the black.
i have these entries in my calculator
then go and press second and the down arrow to lighten your screen. it should work.

this might seem weird.... but have you checked the brightness of your calculator? if someone was playing with it and set the brightness to 0 it wont seem like there is anything. if u press second then hold the up arrow key it will make the screen darker. I dont know if this will help you or not but i know some of my friends like to play pranks where they set the brightness really high.

I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.
Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.
