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.

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.
