Hi,
After changing the batteries the calculator is o restored to factory defaults, but the screen contrast may change. The screen may be too light to see anything. Darken it a bit.
Press [2nd] key and release it.
Press and hold [UpArrow] until screen is dark enough.

Hope it helps.
Thank You for using FixYa and for rating the solution.

When i turn it on a black screen pops up and i cant see the problem im putting it how do i take off the black screen


Try adjusting the screen contrast. To lighten the screen, turn the calculator on, press and release the 2nd key, then press and hold the down-arrow key. To darken the screen, use the up-arrow key instead of the down-arrow.

Hi. I changed the batteries on my TI-86 and when I tried to turn it back on the screen was completely black. Do you know what the issue could be?


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If the screen is completely black, go the other way, using the Down-arrow instead of the Up-arrow.

If this doesn't do it, please reply to this post and we'll go on from there.

Take out one battery. While holding the "On" button, put the battery back in. It may take more than one attempt, but it should start working again. Tell me how it works out, and hope this helps!

My ti-86 screen is black is that normal. I have not used it in years, but i put fresh batteries


Hello, First of all no; it is not normal for your screen to be black. How can you enjoy the wonderfulness that is Ti with a dark screen. For the solution; it sounds like your contrast needs to be adjusted. Hold 2nd and down. The screen should lighten. If it reaches about where you can not see the cursor, then press 2nd and up and this will darken it. Hope this helps; Happy Calculating
