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.

Hello,
If batteries are inserted correctly you can adjust the contrast
Press [2nd] key and release it
Press and hold [UPArrow] key to darken till contrast is dark enough.
To enlighten screen, do as above but use the [DownArrow] key.
Hope it helps.

Hello,
Use the TIconnect or TIGraphlink software to reinstall the programs. You will find the programs in the TI Program archives.

Try pressing (lightly) on the bottom border below the screen. If there is no change, try the top. If there is still no change, the power for your LCD may have become disconnected or shorted. There are external displays for these calculators intended for overhead projectors. If your school has one, you could try hooking it up to make sure the calculator itself still works.
In either case, it would be better to purchase a new calculator.
Good Luck!

Turn the calculator on. Press and release the 2nd key. Press and hold the down-arrow key until the screen lightens. If you go too far, press and release the 2nd key and then press and hold the up-arrow key.
