Calculator stopped working. Yes I replaced all the batteries.

The battery is not the problem, check to make sure the contacts are clean, beyond that it is cheaper to replace the calculator rather than repair it.

In my opinion your calculator may suffer from the depleted battery syndrome. Certainly the first thing one should do is to replace the batteries with a fresh set. If the behavior persits then there is a problem.
There is no set value as to how long a battery should last. It all depends on the frequency and durarion of use.

Having received no response in over a month, I assume it was just a screen contrast problem, fixed as described.

Hi. do you still having your calculator? have you fixed it? If not, i wish to buy it to fix the mine. I have broken the external case and the battery cover. Thanks and regards

If your hold it down for a long time, it may start working. Also, try replacing batteries or just get the button replaced from where your bought it. If you still have your reciept, you may get the whole calculator replaced for free. This is what happened to me 3 days after I got my calculator. I hope that I helped. Bye.

Hi,
Reset the calculator. On the back of the calculator there is a reset button (Above battery compartment and to the left. Use a thin pointed object to push it. The calculator will ask for confirmation to reset all memory back to default. Press [F1] to accept.
And next time avoid hanging out with stupid people, and don't lend them your calculator. Didn't you know that stupidity is contagious?

Hope that helps.
Thank you using FixYa and for rating this solution.

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.

Whenever my calculator has said that, it usually takes a long time, especially if you haven't garbage collected in a while. I don't see why it wouldn't stop eventually, but if it seems like it never will, take out all the batteries and the back up battery behind the door with the screw. Leave them out for like a whole day. When you replace them it should reset your calculator.

I really had to "yank" mine apart. I thought I was going to break it but didn't.

Good luck.

The battery is EPX76 (it uses 2)

This page describes how to get into the calculator to replace them;

The batteries can cost as much as $5 each, a new calculator can be as low as $10

Good Luck!
