Question about Texas Instruments TI-83 Plus Calculator
When my daughter's TI-83 Plus is turned on, a screen of characters flashes, then the screen goes blank. After 5-15 seconds or so, the screen will flash once or twice then go blank again. It keeps cycling through this. The pattern appears to be the same - the leftmost eighth of the screen is pretty much blank, the 2nd, 3rd, 4th, and 7th eighth "columns" mostly have a small "pipe" (|), the farthest 8th "column" is mostly dark. The 5th and 6th eighths are mostly horizontal dark, thick bars.
I'm told it was dropped about 2 months ago. I cannot find a reset button to try. I did try the memory reset (2nd, Enter 712) without noticing any difference.
We've tried two different sets of fresh batteries with the same results.
Thanks for any possible solutions.

I have just done what you said you had done, but I got a nice, correct table of values. You might have discoverd a secret command to clear memory.

it seems it have an internal problem of contact and you must get it repair, or consider buy a new one that model is a little old.

Well, if screen shows the RAM CLEARED message, that means your calculator is working. Just press the [CLEAR] key, message will be erased and you are ready to crunch numbers.
Hope it helps.

Try [2nd], [MODE] or [2nd] [ON] or [CLEAR] or take out a battery, this won't erase anything whatsoever as long as you have the factory back up battery in it, which unless you took it out, don't worry, you have it
