My TI 84 calculator has random symbols that don't erase. none of the buttons really work and the button next to the (2nd) button makes the calculator turn off. however when i turn it back on the...

Reset the calculator by taking out all of the batteries, then hold down the power button for 30 seconds. Replace the batteries and see if it works again. If not, remove all of the batteries again, this time include the backup battery (you'll need a small phillips screwdriver). Wait 5 minutes and reinstall the batteries. Hope it works for you. g.

The buttons on my TI-84 do not work


Do you mean that NONE of the buttons work? Not even the on button?

----------------------------- IF NOT ALL BUTTONS HAVE GONE HAYWIRE ------------------------------------
The contacts underneath the keypad are probably amiss. This is a good thing, a common thing, and an easy thing to fix. You can fix this at home, at no cost, and at your leisure. Here's how:

STEP ONE: Get a skinny screwdriver
STEP TWO: Unscrew all the screws on the back of that screwed up device
STEP THREE: Remove the face plate (use a little care)
STEP FOUR: Examine & fix
4a. Dust off
4b. Re-seat all the soft-key contacts that may be off their rockers
4c. Remove any residue

So, if only a few buttons have gone awry then this should work for your TI-84.

Two of my keys seem to be sticking and a whole row of them don't even work. Can i fix this without sending it back? Its a TI 84 Silver Edition.

Surrounding the keys is a removeable cover. It can sometimes become displaced from its standard position. If you look around the edge of the calculator, it clips in. Use your fingernails to remove and replace it.

I had this same problem and simply removed the cover around the keys.

I jus bought a TI-84. when i turned it on it said RAM cleared. now there's a blinker on the screen. every time i press a button, nothing happens. whats wrong with this brad new calculator

You need to re-install or, update the Ti 84 Plus OS. Since you just bought the calculator it is unusual that it is already to that point of clearing the RAM. You can connect a computer and your Ti 84 calculator together once you downloaded and, installed Ti Connect software on the computer. That way you can use the Ti OS Downloader that comes with Ti Connect software to install the newest Ti 84 Plus OS. Or, if you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84.

Get this problem fixed as quick as you can. You do not want your OS to fail any more than what it already has. If you can not find another calculator to connect too, then you can connect through your computer. You may have a long road ahead of you getting the Ti Connect software and, drivers working right. Just remember to come back to your posting here and, post a comment of what ever is failing. This will notify me right away and, I'll walk you though it if necessary.

My TI-84 keys are not all working; multiplication and division show up as asterisc and clear does not clear. I have just changed all batteries, including small round one and no change

it could be that the old battery leaked inside and cause this problem in most cases this is the problem.

if you want to fix the Calculator let me know
