Try to reboot your calculator to see if it helps by doing 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 if it helps or not.
Nope, I tried that before, and again now - same result. I always get the black pixelated screen, and the only thing that affects the display is to turn it off. If you have any other suggestions, I will gladly give them a try. Thanks - ed.
The other way to try is to erase the whole operating system and install it again. Do you have the cord to connect to the computer?
Yes, I have the USB cable. I'll give that a try. Thanks - ed.
You need a USB silver link cable or a serial link cable. If you have the USB version, install TI-connect on your computer. first. If you have serial link cable, install graph link software for it.
If reinstall the software operating system won't fix the problem then follow this instruction:
# Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
Worked like a charm, THANKS!!!! Just got upset with my daughter for dropping it because it was buried in her backpack and fell to the ground when she pull a book out. She turned on the calculator and had a rectangle of black pixels. But now it is working!!!! Thanks to your instructions!
I also tried to reset the memory twice, but the screen is still dark and non function in working. Unfortunately I don't have the cable to connect the calculator and i cannot reinstal the OS. I'll try to find the cable and try. thanks.

I've had this issue
before with my TI-83 Plus. I'm not sure exactly the solution I used, but these
steps progress through the mildest to most extreme methods of fixing the
calculator.
Solution 1: Take the batteries out.
Odds are you've tried
this already, but it bears mentioning.
With the calculator on,
remove the triple A batteries housed in the back. After a few seconds, replace
them and turn the calculator on.
Solution 2: Clear the RAM.
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.
Solution 3: Reinstall the operating system
Remove one of the AAA
batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA
battery and then turn the calculator on. The calculator should display "Waiting...Please
install calculator software now"
Here is the website to reinstall your OS.
First you'll need the TI-Connect
software.
Solution 4: Remove all sources of power. This is a risky move, but if your
calculator will absolutely not work after you try even reinstalling the
operating system, it might be your last hope.
Remove all of the batteries
including the round lithium battery for 5 minutes. After the 5 minute period,
reinsert all of the batteries and turn the calculator on. Adjust the contrast
if necessary.
