Try to reset everything to see if that helps. If it doesn't , you can try to upgrade your operating system on the calculator to see if that helps to make it go away.
If that doesn't help try this:
"Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message."
Let me know how it goes.

I accidentally pressed the 2nd button and then the left side arrow button and now I have this black grid on my screen that I cant figure out how to get rid of if I tilt the screen I can see what I'm trying...

Displaying the grid on the screen is a graphing option accessed through the command GridOn. To turn the grid off, press [2nd][ZOOM] (FORMAT). Use down arrow to reach the 3rd line. Highlight GridOff and press [ENTER]. Press Graph to return to the graph screen.

How you activated the GridOn command by a single press of a button is a prowess. I wish you could teach me this legerdemain.

Hope it helps.

Clearing TI-83 screen

The CLEAR key will do that for most functions. However, if you are in some modes, like MATRIX>EDIT or STAT>EDIT, you will have to press 2nd+QUIT (the MODE button) to get back to a the regular screen, which you can then clear with the CLEAR key.
