    Try adjusting the contrast. Turn the calculator on. Press and release the 2nd key. Press and hold the down-arrow key for a few seconds and see whether the screen lightens. Does it?

Having received no response in over a month, I assume it was just a contrast problem.

My son's TI-83 calculator screen is very dark. The calculator appears to be working but I can barely read the screen. Any suggestions?


Try adjusting the screen contrast. Turn the calculator on. Press and release the 2ND key, then press and hold the down-arrow key to darken the text. If you go too far, use the 2ND and up-arrow keys to lighten the text.

Turned on ti 86 and have a black screen. I have replaced all of the batteries and still is black.


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), or try reset button (a small hole which a pin can only be used to press it to RESET. Gud Luck

I have a TI-83 that hasn't been used for a couple of years. I replaced tha 4 AAA batteries, turned on the calculator, but the screen just displayed one horizontal black line. I couldn't get it to respond...


Hello,
Hope is what keeps the world turning.
Clean the electrical terminals even if they seem shiny. Use a clean eraser tip of a pencil.

Insert the main batteries.
If you see the line again, press [CLEAR] to see if it disappears.
Try resetting the RAM by pressing [2nd][MEM][7:Reset][1:All Ram][2:Reset] [ENTER][ENTER].

If screen is too light or too dark, adjust the contrast:
Press [2nd] key and release it
Press and HOLD Arrow (UP to darken, or DOWN to lighten) the screen.

If that does not solve the problem you may have to force the calculator to boot up. Details are in the article . Read the part on Ti83Plus family.
The article contains links to additional articles.
Hope it helps.

I don't have the book and I don't know how to shut it off...TI-83


Sorry, but you cannot. That is the cursor, and it is equivalent to the cursor you see on your computer when typing text. You can change the resolution of the screen by pressing 2ND then the up and down keys, but this will change the resolution of EVERYTHING that is on the screen, not just the cursor.

Small black square in top left...won't turn off


You should replace the AAA batteries with new ones, and should by a new set of back up batteries.
