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.
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.
If that doesn't work, try a hard reset. Remove one of the four AAA batteries. Press and hold the ON key. While holding down the ON key, replace the battery.
Hi, The applications that run on the TI84Plus Sliver Edition run without a hitch on the TI84Plus and also on the TI83Plus. The only major difference between the 84Plus and the 84Plus SE is the amount of flash memory. Here is what I would suggest to you.
Replace the main batteries with fresh ones.
Adjust the screen contrast: a. Press [2nd] key and release it. b. Press and HOLD [UpArrow] to darken or [DownArrow] to lighten screen.
Clear the calculator Ram. Usually it is cleared if the calculator is left without main batteries for a while,but you never know.
To clear the Ram, press [2nd][MEM][7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the "Ram Cleared" message.
If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.
About the only thing that I can can think of is that you may need to replace the internal battery. It is located in a little door with a screw right above the AAA batteries.
Another thought. The calculator may be staying on and not doing an auto shutoff. The calculator should turn itself off if you forget to turn it off. You can check to see if this is happening by leaving the calculator on, going back later and checking to see if it turned itself off.
