Have you attempted darkening the display on the calculator through the function keys? Push "2nd" and then push "up" a few times. After resetting the calculator, this setting will always revert to a lower, unreadable setting. I'm sure TI knows about this, but they probably arent too inclined to fix it.

Is there a way to change the contrast as two of my units have a barely readable screen as the numbers are too light to read easy

Too light numbers usually indicate weak batteries. If you're sure the batteries are new then the display is done.

It just went display, changed batteries and still nothing. I was using it when this happened.

It is possible that the calculator went dead because the main batteries were depleted. However when you change the main batteries, it is often the case that the display contrast changes, and may become too light for you to see anything. If that is the case, you can increase the contrast of the screen.
Press the [2nd] key and release it.
Press and HOLD the [UpArrow].

The contrast should increase and the screen darkens. Keep pressing the UpArrow until the display is satisfactory to you.

Display is faint and to light to read

Turn the calculator on. Hold down the "C" key (just above the ON key) and press + to darken the screen. If you go too far, use the C and - keys to lighten the screen.

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.

Screen is very dark the numbers are there but barely readable

Your batteries may be getting low. Try changing the batteries. If this doesn't help, you can make the screen lighter by:

1. pressing and releasing "2nd"
2. pressing and holding the down arrow until you receive a desired display.

Display is really light

there's no way to adjust the contrast on the TI-30XA unfortunately. you can try changing the batteries but beyond that, there's not much you can do.

What do i do if the calculater will not turn back on ? i installed new batteries already

The most common problem in the TI calculators is not a real problem at all. When you replace batteries, the screen display may become too light and you cannot see that the calculator is already ON.
Increase the darkness of the display. Here is how to do it.
  1. Press the [2nd] key and release it.
  2. Press the UP navigational arrow and HOLD the pressure.
On the Top right corner of the screen a number is displayed (between 0 and 9). The value changes as the screen contrast changes.
When the contrast is adequate (to your liking) release the Up arrow.

Ti-83 Plus weird display problem (detail included)

Warning the following tip will erase apps and programs from calculator!
The following will run the self-test mode
Press mode then press alpha then press s then press enter
If you want to get out of the self test press the on button in case you want to attempt to save/transfer apps, programs, variables etc.
The calculator will start to test itself it'll countdown and display numbers on the screen. It can get better sometimes other times a replacement of both the cr1616/cr1620 lithium battery and the 4 AAAA batteries work. Also ensure that you've attempted to clear out all the memory and reset the calculator. To delete all variables, tables, graphs, etc: Press 2nd button then press MEM then press 2 then press 1.
To reset the calculator press 2nd button then press MEM then press 7 then press the left arrow then press 1 then press 2.

Calculator will not come on

I have the same problem with the calc not responding to removing one batt and reinstalling while holding clear, etc. My fix is to hook up wires to the battery leads and plug the wire into a 120 volt outlet. Watch it light up, but do NOT breath the smoke as it is extremely toxic. ;-) lkw
