You apparently have the base set to something other than decimal. Press 2nd [MODE]. Use the arrow keys to move down to the sixth line, select "Dec", then press EXIT.

Remove and replace the batteries should be first step. Also, I believe these have a smaller button-cell backup battery as well. Replace and reset to factory settings (backup any saved info if you can link with another TI calculator).

First make sure the cable at the top of the screen is not pealing off near the edge, on the inside of the calcualtor. You may need to peal it off and reattach it, align the strip with the metal coating strips on the glass, you will see the strips when viewing the glass at an angle, but that is risky because you may not be able to reattach it. Next check the small square that says "8" on the back of the display board, you will see minature wires, make sure all the wires are lined up properly, if not thats a factory defect. Goodluck.
