Your LCD is dying. You need a new inverter.

Try this- Press power + volume down , keys until the phone vibrates (about 8-10 seconds). See if it switches ON ..

If not wait till the Battery is completely drained. Then connect the charger .. Leave it for about an hour and see if it has switched ON on its own .. Else try the reset once again

When I turn the calculator on, I get a black screen. It won't go away.


Most likely the screen contrast is too high. Try to lighten screen
Press [2nd] key and release it
Press and Hold [DownArrow] until screen lightens to your liking.

As you keep pressing DownArrow, the top right corner shows a number that decreases as the screen lightens.

When I turn my TI-83 on I see a black screen....What can I do


Hi,
The screen contrast of the TI83Plus/TI84Plus/TI84PLUS SE can be adjusted to suit the user. Sometimes after the batterie have been replaced the screen contrast is reset to the factory defaults.
To adjust it to your liking.
  1. Press the [2nd] key and release it.
  2. Press and hold the Down Arrow key to lighten the screen or the UP arrow to darken it.
In your case, the screen is too dark, so in step 2 above you press and hold the Down arrow until the screen lightens enough.
Hope it helps.
