We put new batteries in the TI-85 but the screen is now black and it is very difficult to read.

Adjust the contrast. Turn the calculator on. Press and release the 2nd key. Press and hold the down-arrow for a few seconds key until the screen lightens. Obviously, if you go too far, press and release the 2nd key and then press and hold the up-arrow key.

turn the TI-85 on and then hit the yellow "2nd" button and then down arrow. This may take several repeats. If it gets too light hit "2nd" and Up arrow.

I've replace battiers in my TI-85 and now when I turn it on there is a black screen. I can turn off. What do I do to clear screen?

After battery replacement, the screen contrast is liable to change: It may be too dark (your current case) or too light. You must adjust the contrast.
  1. Press [2nd] key and release it.
  2. Press an d HOLD one one of the navigation arrows
  • Down arrow to lighten screen (your current case)
  • Up Arrow to darken.
Keep pressing the relevant arrow key until the contrast is adequate.

Screen color

It's not a color screen so no, you can't change the color. You can, however, change the contrast. Press and release the 2ND key, then press and hold the up-arrow to increase or down-arrow to decrease the contrast.

TI 85 doesn,t turn on. I didn't use the calculator for a year. Please help !

Assuming good batteries, both AAA and the Memory CR 1616, then most often a screen contrast problem. Push ON, Then 2nd button (yellow Key) , then UP arrow, then either UP or Down arrow
to set your contrast. Good Luck, Calculator should show the screen calculations now, so you can tell if it is on or not.............Not that it wasn't working, you just couldn't see it working or coming on......

My TI-85 will not come on

Screen contrast problem. When the calculator lost power the contrast was reset to zero.
If new batteries, both AAA and Memory battery CR 1616, then press ON, then 2nd (yellow
Key), then UP arrow, More UP arrow if desired contrast is needed more. You should see the
display or screen effectively. It is not that it would not turn on, it was just that you couldn't
see the display, it was set too low for observation............................It was on just couldn't see it.......
