    What happens if you try to decrease the contrast by pressing and releasing the 2ND key and then pressing and holding the down-arrow key?

Having received no response to my query, I assume my suggested contrast adjustment solved the problem.

Turn the calculator on. Press then release the 2ND key. Press and hold the down-arrow key to lighten the screen. If you go too far, you can use the 2ND and up-arrow keys to darken it again.

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.
