Question about Texas Instruments TI-83 Plus Calculator
Whenever the screen is full and a line with calculation result comes up at the bottom of the screen, the screen all of a sudden shows things in a weird way and can't be read. By press "2nd+mode"(=quit), it gets back to normal. but this pattern repeats forever. Every time screen is full, and a new line comes up at the botton of the screen, the weird display problem repeats. Does anybody can help me?
Warning the following tip will erase apps and programs from calculator!
The following will run the self-test mode
Press mode then press alpha then press s then press enter
If you want to get out of the self test press the on button in case you want to attempt to save/transfer apps, programs, variables etc.
The calculator will start to test itself it'll countdown and display numbers on the screen. It can get better sometimes other times a replacement of both the cr1616/cr1620 lithium battery and the 4 AAAA batteries work. Also ensure that you've attempted to clear out all the memory and reset the calculator. To delete all variables, tables, graphs, etc: Press 2nd button then press MEM then press 2 then press 1.
To reset the calculator press 2nd button then press MEM then press 7 then press the left arrow then press 1 then press 2.

I had the same problem for a long time, I just let it sit there without the batteries for a while (a few weeks) and then plugged the batteries back in, hit 2nd+MODE(Quit) and it worked just fine after that. Also try to take out the little battery in the back, the memory battery, maybe that will fix it. Good luck.

Is there a tiny hole in the unit to push in a pin to reset it?

no, it doesn't have a hole.
I have exactly the same problem. I've installed the latest OS and even called Texas Instruments. They tried everything they knew of and couldn't get it fixed. I guess we either have to deal with it or buy a new calculator.
Sorry.
YEAH I ALSO HAVE THIS PROBLEM!! ANYONE KNOW HOW TO FIX IT?!
i have the same problem there is some vertical lines that come up everywhere .... when graphing when doing normal calculation and everything... i try to reset all thinking that that was the problem ... it didnt fix it ... then magically after a while it was back to normal ... and now the day before a math test the calculator went nuts again...
sounds like mine, i tried reseting to the factory defaults, and that did not change the problem. only really happens when i hit the last lines of the screen. and in menus where there are words all over the page, there is strange distortion all over the page.
no, nothing has worked and i realllyy don't want a new calculator!!! what can i do???? columns on my screen (5th and 3rd-to-last) don't even work, and random vertical lines appear!!! is there some way to fix this? :'(
