My ti-84 se plus has batteries that work, but it isn't turning on do you know why?


Personally I do not know why because I do not lnow what the calculator went through. However, if the calculator was working correctly but after you changed the batteries it does not seem to come alive when you press the ON button, then I may have an idea. Here it is.

After you change batteries, the screen may become too dim or too dark. For your case it may be too dimm.

To darken the screen, follow the procedure below.
1. Press the [2nd] key and release it.
2. Press the UpArrow and hold pressure on it (to darken screen) or DownArrow to lighten screen.
As you keep the UpArrow held down, you will see somes numbers at the top right corner of the screen. You mifgt first see a 2 or a 3, then the next number and it keep increasingAfter a while it becomes too dark to see anything.

To lighten the screen
1. Press the [2nd] key and release it.
2. Press the and hold the DownArrow
As you keep the DownArrow held down, you will see somes numbers at the top right corner of the screen. You mifgt first see a 8 or 7 , then the next number and it keeps decreasing.

Release the Arrow keys when the screen contrast is to your liking.
If you overshoot your intended screen contrast you can revert the process by reverting the procedure.

My screen for my TI-83 is turning black and I can't get it off


How to Change the Brightness of the Display

To darken the display, press the yellow 2nd button and then press and hold down the Up-Arrow button located in the upper right section of the keypad. Release the Up-Arrow button when the display has reached the desired level of darkness.

To lighten the display, press the yellow 2nd button and then press and hold down the Down-Arrow button. Release the Down-Arrow button when the display has reached the desired level of lightness.

As you go through this process, a number will appear at the top right corner of the display. If this number is 7 or higher when your screen reaches the desired level of brightness, then your batteries are getting low and may need replacing soon. This number will be approximately 3 or 4 for new batteries.

My ti - 83 hasn't been used in a while, placed new batteries in it and all i get is dark screen.....it won't even turn off......there is just a dark screen......any ideas what causing this and how to fix...


The most probable cause (at least I hope so) is that the screen got too dark after you changed the batteries. It is a common occurrence: Screen becomes too dark or too light.
To adjust the screen contrast:
  1. Press ^2nd key and release it.
  2. Press and HOLD the DownArrow key until screen lightens to your taste.

Did you try [left][right][2nd][on]? It reinitializes the memory and clears the ram.
