Re: On/off button doesnt turn on

Normally if you spill any type of liquid that would certainly affect your calculator from working- i would say that you need to have it replaced

Water from a water bottle spilled all over my TI-84 Calculator. I dried it the best I could and replaced the batteries after drying them but none of the buttons work and it won't turn or. And way I can...

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.

I also hope you let the calculator dry out thoroughly before replacing the batteries.

My calculater has everything on the screen but its really light. I put in new batteries and it still doesnt work. Its a ti-84.

Turn the calculator on. Press and release the 2ND button. Press and hold the up-arrow button to increase the screen contrast. If you go too far, use the 2ND and down-arrow buttons to decrease the contrast.

There's something wrong with my TI-83. When I'm typing up an equation it will randomly shut off. And when it's on it will have shown that the RAM was cleared. Now it sometimes takes like 5 presses of the...

Have you tried changing the batteries? I'd try that first thing. From your description, the problem sounds like you have low batteries. The RAM shouldn't clear itself when you turn the calculator on unless you tried to turn it on when the calculator didn't have any juice. The TI-83 has four AAA batteries and one CR1616 battery it uses for memory backup. The CR1616 isn't enough to power the calculator, just enough to keep your calculator from losing its RAM contents while the primary batteries are out. If you try to power the calculator on without primary batteries, the backup fails. However, the TI-8x line is usually pretty good about warning you when the batteries are low by displaying a big warning message when you turn it on about the batteries being low and a recommended change of batteries. It might not, though, so you really can't be sure until you try a fresh set of batteries. Good luck!

My daughters's calculator got wet when something spilled in her book bag. We took out the batteries and let it dry out. Later we put in new batteries and it works but is extremely slow and I have to press...

If water was spilled in it, the batteries should have been removed immediately, if you could remove the circuit board from the casing, dry it off and place it under a lamp for a few hours it should have been perfectly fine. If a soft drink, sugar base or other substance was spilled in it; the board would need to be cleaned, a small amount of soap and water can work, use a cotton swab, only clean the affected area of the spill, make sure to rinse all the soap off, dry with towel, then place under a lamp to get all the moisture out. Also make sure you clean the bottom side of the buttons that contact the circuit board. If it doesn't work then you may have to buy another unit.

When i turn on the calculator i get a dark screen and when i try to adjust the con trast it doesnt change

this is what i think you mean, if i diss-understood you (thought you mean something else) im sorry, then i dont know what to do
thats when you set your ti 84+ screen to very dark. this is how to solve it:
go and open mirage OS, and then just press the "-" (minus) button. the screen should get lighter.

Dosen't Turn on

I would suggest fresh batteries. If I remember correctly the battery compartment is on the back of the device, and I think it uses AAA

Ti-84+ turns on but no key function

Hi everyone,
I just had the same problem with my calculator. Only the On button worked, but nothing else. So I plugged in my calculator to my computer and I reinstalled the latest OS (2.43 I think). That didn't do anything, so I reinstalled OS version 2.22, a very old one. That made my calculator work! I think there is a problem with the 2.43 OS. I haven't tried upgrading my calculator any higher than 2.22. I'm sure 2.30 could work. Good luck. If anyone needs help in installing a new OS, I can help you.

Sharp calculator

I had the same problem happen to me. What I did was carefully take the calculator apart using a T-10 Torx screwdriver to remove the back cover. I then used a compressed air can and blew air into all the crevices and holes in the calculator. I was able to dry almost all of the soda the spilled, however some of the soda dried and turned into somewhat of a sticky mess. I was able to carefully wipe the sticky parts clean with a tissue. After doing all of that my calculator worked perfect.
