Adjust the screen contrast. Turn on the calculator. Press and release the 2ND key, then press and hold the down-arrow key for a couple of seconds. If you go too far, use the 2ND and up-arrow keys.

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

I stop using my TI-86 for a few months and know


I hadn't used mine in years and had the same problem. Essentially you just need to give it a workout to get all the pixels working properly again and then it'll be just fine. I adjusted the contrast between full dark and nothing multiple times and turned the calculator on and off after each cycle and now it works like new.

Why is my TI-86 screen dark when i turn it on?


Having gone over a month without a response, I assume it was just the screen contrast.

Changed battery, still not turning on. what do i do?


The most frequent cause for this ''not turning on'' is a screen that is too light to see anything displayed. Try increasing the screen darkness.
Press 2nd key and release it
Press and hold the Up Arrow until it is dark enough.

If the does not work
  1. Press 2nd key and relese it
  2. Press UpArrow and release it
  3. Repeat the two steps until screen is dark enough.
