TI-82 Screen Not Working or Black

I tried using my TI-82, which hasn't been used since I graduated in May, and the batteries were dead. I replaced all of them including the backup battery, and now, when I turn it on, all I get is a blank, dark screen (every pixel is at the darkest setting). Adjusting the brightness (2nd + down/up arrow) does not have any effect. What do I do?

Re: TI-82 Screen Not Working or Black

Try a hard reset. Take out all the batteries, and while putting them back in, hold down the "DEL" key. Then, turn it back on and you can adjust the contrast by pressing the "2nd" key and the down arrow at the same time. I just got this info. online and it finally worked for me...good luck!

I have a TI-82 how do you replace the battery.

Push down the tab and lift off the battery cover on the back of the calculator.

To replace the four AAA batteries, simply pull them out and put in new ones, following the polarity indicators. To replace the backup battery, unscrew the cover, pull out the battery, put in the new one, and replace the cover.

TI-84 Plus Silver Edt...unable to power up

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 that doesn't work, try a hard reset. Remove one of the four AAA batteries. Press and hold the ON key. While holding down the ON key, replace the battery.

I have an older 1995 TI-82 that suddenly will not turn on. I changed the batteries including the watch battery and still nothing. Is there a reset or do you have a suggestion?

The following are 4 different things you can try that is on the Texas Instruments Website: " 1. Try a new set of AAA batteries. 2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow. 3. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the AAA battery and then turn the calculator on. 4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. "

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.

try this, try reseting the calculator blind. hit 2nd then + then 7 then 1 then 2. That's how you reset it on an 83,84,89 and so on. if you have a friend see how he resets his 82 and try it the same way. It could just be that your screen is ruined. this can happen if it gets alot of pressure in a back pack. GOOD LUCK

Well, in most calculators, the action of taking out the backup battery practically clears the whole thing. Memory, everything. I myself have a Ti-89 and have not yet experienced this problem, but I have on an older Ti-82 and removed the backup battery and the whole thing is dead now, or at least nothing happens when I turn it on, even after replacing the batteries again. If you still have the manual, I would check out the troubleshooting. If you don't have it, try to find it online. And if you have done both of these things, try getting hold of technical support through Texas Instruments.

If you haven't tried this already, adjust the brightness (2nd + Up Arrow). Also, the backup battery, which is removed by unscrewing a small plastic panel in the battery compartment, may need to be replaced as well.
