TI-81 when turned on, screen is totally black, can perform calculations & barely see results on screen. is this a battery problem?

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

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.

Black Screen

Not for sure but if it has a reset button on the back you probably need to press and hold it for about 10 seconds and see what happens.

My screen will not work

Mine had a problem like that, just that the screen had become blue. I later found out that someone had gone to the contrast mode and made my screen that way. I am sure we have the same problem, but you can try and see. Wish you luck.

Screen fully black

Black-Screen/Black-Pixel Fix for TI-Calculator

This will erase all memory and reset defaults.

1. Remove 1 AAA Battery
2. Press and Hold 'ON' for 30 seconds
3. Replace AAA Battery
4. Adjust Contrast to appropriate level

If this fails, try again with ALL Batteries removed including
the backup Lithium Battery.

If all else fails, try the following reset procedure:

1. Remove ALL Batteries (inc. Backup)
2. Let Calculator sit with no batteries for 2~4 hours.
3. Hold 'ON' for 30 seconds.
4. Replace all the batteries (May be good idea to use new batteries
just in case old ones were dead)
5. Turn on Calculator
6. Change Contrast to appropriate level

- Remember to use correct batteries or calculator may not work. The
correct batteries are Alkaline, Rechargable Batteries are TOO WEAK,
Heavy Duty batteries are TOO STRONG.

Help!!a Black screen appears when I turn on my calculator

ok guys, after about 10 years of not using my ti-83, i put the new batteries in and got the black screen you are all talking about.. came to this site.. saw no solutions.. kept looking.
I've fixed my calculator, but my brain won't tell me exactly how.. but i followed those instructions..
you CAN see what is on your screen if you tilt it under the light ... just fiddle around until you can see faint writing on your screen under the black.
Press window

i have these entries in my calculator

then go and press second and the down arrow to lighten your screen. it should work.

You can try to turn the contrast down by pressing 2nd and then hold "down" If the screen does not fix, put new batteries in (including the back up batteries). The problem will be resolved. Hope this helps...
