I got frustrated with mine so I started to press the 2nd, then releasing, then hitting the down arrow, and back and forth... and it worked! Please try this instead, it worked and I've been trying to use the hold and press this and that, but the alternating worked better!

SOURCE: How do you set the contrast on the TI-85? My

Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key until the screen is to your liking. Obviously, if you go too far, you can press and release the 2ND key and then press and hold the up-arrow key to go the other way.

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.

Ti 84 plus wont work


TI calculators have an annoying habit of dimming the screen, especially 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 this isn't the problem, please reply to this post and give a fuller description of the problem.

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?

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.
