    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.

    Does it?

Having gone over five months without a response, I assume the suggested contrast adjustment solved the problem.

My TI-83 PLUS wont turn on


Remove one battery from the calculator and then press and hold down the CLEAR key while re-installing the battery. While continuing to hold down the CLEAR key, press and hold down the ON key. If this doesn't work, then hold DEL and then ON. If unsuccessful, remove all the batteries, including the lithium watch battery, and leave the calculator like that for a while.

This is documented in the TI-83 Plus Guidebook, but unfortunately, not many people know about it.


If that doesn't work, send it to TI for repair. They probably won't even charge you!

No display at all, does not seem to be turning on, yes I replaced the batteries.....any thoughts?


Hello,

If new batteries did not solve the problem, the next thing to check would be the battery terminal.

If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.

If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.

If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.

If non of the above helps, then it means the calculator is dead and needs a replacement.

Regards.

It's "frozen". won't change from the screen its


Try to reset it by taking out the batteries and leaving to sit for a minute or so, if that doesn't work take out the small battery as well and leave it sit, if you're still stuck you can call ti-cares (800-842-2737) they're generally very helpful.

My ti 84 plus does not want to turn on, i thought it was battery problem so, i bought new batteries but i stil have a blank screen.


Could it be that your screen has been dimmed in error. Turn the calculator on & press the 2nd key and then the up arrow. This darkens the screen.

If this doesn't work, try taking out the backup battery. It is located in the battery compartment, behind a little door that you must take off with a phillips screwdriver. Leave it out for about 10 hours. If this doesn't work, try replacing the backup battery.

Hope this helps.

Your calculator may need to be reset. Open the battery door. There's an internal battery behind a little door with a screw right above the 4 AAA batteries. Take this battery out. Leave it out for about 8 hours then put it and the AAA batteries back in. Hopefully this will solve your problem.
