Glitched vertical lines on TI-82 Stats.
A few days ago, I dropped my TI-82 Stats calculator. At the same time, the batteries ran out, so I'm not quite sure which of them caused the problem. Anyways, when I had inserted new batteries, the screen had thick glitched vertical lines that obscure every other character. The "glitched" lines mostly look like a "ladder"-pattern, but there is a thicker line in the middle, what looks like noise to the far left, and there are some missing pixels here and there. It has looked like that since I pressed the graph button (or whatever it's called, I don't have the calculator here right now). Before that, it was an even thicker pattern. Does anyone know what the problem could be and how to fix it?
Is dit een goede vraag?
