    I get a black line across the middle of the screen, then it fades away. I checked batteries and they are fine. Tried new batteries same thing. I tried cleaning the connections with a pencil eraser, which often works, same thing.

TI calculators seem to 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.

My calculator ti-84 plus is having problems. When i turn it on it will turn off quickly by itself. and while its on i try to click on any botton and it doesnt show the number etc


It could be that the main batteries are drained and are no longer able to supply power to the calculator. Replace the AA batteries with a fresh set. After replacing the batteries the display may become too dark or too dim. To set the correct contrast
Press [2nd] key and release it.
Press and maintain pressure on UpArrow to increase contrast (darken screen), OR on DownArrow to decrease it (lighten screen). If you overshoot your intented contrast you can revert the processs.

Was using the calculator today, then it shut down...will not power-up...the AAA batteries work on other devices

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.

If that doesn't work, try resetting the calculator. Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries and turn the calculator back on (you may have to adjust the screen contrast as described above).

I do not see anything on the screen. I replaced


First try turning the calculator on and then pressing the 2nd key. Hold down the "up arrow". If the contrast has been turned down, this should turn it up.

If that doesn't work, could be that your calculator needs to be reset. Take out the internal battery located right above the 4 AAA batteries behind a small door with a screw. Leave all batteries out for about 8 hours. Reassemble and hopefully you can turn it on. If this doesn't work, you might replacing the internal battery. Hopefully one of these solutions will work.

this might seem weird.... but have you checked the brightness of your calculator? if someone was playing with it and set the brightness to 0 it wont seem like there is anything. if u press second then hold the up arrow key it will make the screen darker. I dont know if this will help you or not but i know some of my friends like to play pranks where they set the brightness really high.
