Question about Texas Instruments TI-83 Plus Calculator

Ti-83 plus silver edition for overhead projector hook-up

The calc was ok in may. Now it won't come on. I put in new batteries and checked the contrast, still no luck. It has not been dropped or mistreated. I am a math teacher. It just won't come on. I made sure all keys work (push in ok). I have a second one that is just a regular 83 plus that has a damaged screen that needs replacing. Can you fix that?

You can try to put fresh Back-Up batteries into the calculator. If not, you can always call the customer support at Texas Instruments to see if you can get a replacement part for your calculator. This may resolve the problem you are currently having. Hope this helps.

Does not power up after corroded batteries are replaced.


Sometimes these is corrosion on the contacts from the corroded batteries. Try cleaning it off with some sandpaper. Make sure to thoroughly wash your hands after or use gloves!

Good luck.

Won;t power up at all. New batteries but I did not replace back up battery. should I? Tried the contrast fix. Son said he dropped it and it got kicked down hall at school. One year old. Any hope?


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.

Calc north not working


Are you running this scope off of the internal batteries? If you are put in fresh batteries. The hand controller will go wacko once the batteries fall below about 60% charge. We always recommend that goto scopes be run from a separate 12 volt power pack. If new batteries to not solve the problem, return the scope to the dealer while it is still under warranty.

Ti 84 not working


Hello,
Since it gets tossed around a lot, it is possible though improbable that the batteries lose contacts with the electrical terminals.
You may try to darken the screen a bit.
1. Press [2nd] key and release it
2. Press [UpArrow] and release it.
3. Repeat steps 1 and 2 in sequence until contrast is satisfactory.

If that does not fix the problem, use a calc-to-calc cable and try sending something to it from a working calculator.

You can also download the TIConnect software from education.ti.com and install it on your computer. Then connect the calculator to the computer by means of a USB cable, a TISilverCable, or a TI Graphlink (Black cable). Turn the calculator ON, run TIConnect, connect calc-to-computer and Click TIDEVICEINFO in TIconnect main window.

If it tells you NOT FOUND, on any of the ports, click the communication settings: Set the device type to you calculator model. Set the cable type. Set the port (COM x) or USB1
If calculator is not detected through any of the available ports (COM ports, or USB), then it would suggest that calculator is in need of repairs.

Hope it helps.

I recently put batteries in and it wont turn on


Hello,
First you should try to reduce contrast
1.Press [2nd] yellow key and release it
2.Press [DownArrow] key then release it
3. Keep doing the 2 steps in sequence untill the screen is lighter.

If that does not solve your problem
Use the link below to install TIConnect software
http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html You can also download the latest OS there.

Install TI connect on your computer and run it to open the main Window. Then connect you calculator to a USB port and, in the TIConnect main window Click the TIDeviceInfo icon. Software will try to retrieve the info. If it does your calculator is fine.

If it tells you Device Not found , Click communication settings in same pop up window where it said Not found, and Select Device, Select Cable, Select Port and Click OK..

If you are lucky and it works, you should reinstall the OS, which can be downloaded from education.ti.com. You drag and drop the OS on the TIconnect main window. Calculator must of couse be connected to computer.

If you have problem with TIconnect, use the calc-to-calc cable to transfer the OS of a working calculator. Yous should be on Receive mode [2nd][Link] --->>Receive. (When both calculators are ready hit enter.) The other calculator, you guessed exactly right, must be on Send [2nd][Link][SEND][G:SendOS]. (When both calculators hit [ENTER])

If all that does not work, then it may be time to head for a place of worship to pray for its resurection, or look for a repair shop.
Hope it helps
