Question about Texas Instruments TI-83 Plus Calculator
A checkerboard cursor indicates a full memory. Press 2ND MEM 2 to bring up the memory management editor, and start deleting unwanted items.
If that doesn't work, try a hard reset. Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Turn the calculator back on.

There is a cable called isotropic tape. It is a silver tape with lines in it that goes from the main circuit board to the display board. You have to open the calculator to see it. You have to carefully press on the contact areas between the tape and the circuit boards. The tape sometimes comes undone because of heat. YOU MUST BE STATICALLY GROUNDED TO OPEN THE CALCULATOR OR STATIC ELECTRICITY CAN DAMAGE CHIPS. I would highly reccomend using a microscope or magnifying glass when pressing on the tape contact areas. Do not press on the tape where there is no circuit to back up the tape or you can rip it! This may also fix the black screen problem which I sometimes had. Good luck.
