    I haven't used my TI-86 for a few years now and upon restarting it with new batteries, the screen has black lines through it (this doesn't resolve when I change the screen resolution).

My Ti-86 wont turn on after i change the batteries


This may sound silly but check that you put the batteries in the correct way round for (-) and (+)?

Still dark screen after trying to hold down the second key and then the down arrow


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!

I've had my ti-86 for a very long time & recently it just quit working. I changed the AAA batteries & the back up battery & it will not come back on. Please help???!!!!


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. Does it?

My screen is black after putting in new batteries in my TI-86


Adjust the contrast. Turn the calculator on. Press and release the 2nd key. Press and hold the down-arrow key until the screen lightens. If you go too far, repeat the process using the up-arrow key instead of the down-arrow.

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.

My TI 86 is 6 years old and I have taken careof it well.


Try pressing (lightly) on the bottom border below the screen. If there is no change, try the top. If there is still no change, the power for your LCD may have become disconnected or shorted. There are external displays for these calculators intended for overhead projectors. If your school has one, you could try hooking it up to make sure the calculator itself still works.

In either case, it would be better to purchase a new calculator.

Good Luck!

Cracked TI-86 screen


well this isn't looking to good for you? The TI 86 isn't made anymore, so I doubt you can get it replaced. your luck has kinda run dry. You are probably going to have to buy a new calculator. Sorry to be the barer of bad news. Good luck though.
