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?
Hi This is usually one of two things 1)a dodgy screen connection,the screen connector on this calculator is soldered to the main board this can be sometimes be fixed by resoldering the connections with a soldering iron Here’s a guide on doing it https://m.youtube.com/watch?v=mY-tI4WQDf… 2) it could be that the screen is internally damaged ,if this is the case the screen will need replacing The guide linked above has the disassembly guide in it If you need a part you will probably need to get a donor calculator as these parts don’t seem to be readily available Hopefully this helps Any questions please ask Thanks:-)
