ok guys, after about 10 years of not using my ti-83, i put the new batteries in and got the black screen you are all talking about.. came to this site.. saw no solutions.. kept looking.
I've fixed my calculator, but my brain won't tell me exactly how.. but i followed those instructions..
you CAN see what is on your screen if you tilt it under the light ... just fiddle around until you can see faint writing on your screen under the black.
Press window

i have these entries in my calculator
xmin=-10
xmax=10
xscl=1
ymin=-10
ymax=10
yscl=5
xres=2

then go and press second and the down arrow to lighten your screen. it should work.

SOURCE: TI-83 Plus silver edition won't turn on.

the screen may be at the lowest dim setting, try turning it on, then pressing the 2nd key and then hold the up key and see if anything appears, if not let me know and I will try to figure out something else, I own a 83, 84, and 89 so it shouldn't be too hard to figure out

I'm not sure if this will help you patchesb7; it sounds like your calculator is having issues :(
This will help others whose calculators suddenly won't turn on anymore, even after changing the batteries.

Note: This will return the calculator to the way it was when you got it out of the package. Any data or programs have stored since will be lost.

Step 1: Remove all four AAA batteries.

Note: You will have to hold down the CLEAR button while doing Steps 2 and 3. Do not let go until after you have pushed ON in Step 3. I found this easiest to do by holding the calculator upside in my left hand with my pointer finger holding the CLEAR button so the ON button was easier to access.

Step 2: Hold down the CLEAR button (located under the arrow keys) and reinstall the AAA batteries.

Step 3: Press ON button and then let go of both buttons. The screen should say the RAM has been cleared. Press CLEAR to continue.

this might seem weird.... but have you checked the brightness of your calculator? if someone was playing with it and set the brightness to 0 it wont seem like there is anything. if u press second then hold the up arrow key it will make the screen darker. I dont know if this will help you or not but i know some of my friends like to play pranks where they set the brightness really high.

After a battery replacement the screen contrast may become too dark or too light. I suspect that in your case the screen is too light. To darken it
Press [2nd] key and release it.
Press and HOLD [UpArrow] until screen darkens enough.
