Question about Texas Instruments TI-83 Plus Calculator
I can see the screen in the back, if i tilt the calculator a certain way, but if i look straight at it, I see nothing. I tried the contrast buttons, and that did not work, and i tried replacing the Back-Up Battery, and the regular battery, and that did not work. I know it is not the physical screen that is screwed up, because if I turn the calculator off, it goes back to normal...PLEASE HELP!!!
Make sure you hit the 2nd button before hitting the contrast button. you need to hit the 2nd button everytime you hit the contrast up button
