How do I take off the foil cover of a TI-84 plus calculator?
I am a junior in high school and I have a TI-84 Plus calculator, the screen of which has a few horizontal lines of dead pixels (the bag it was in was damp), but everything else works. I am trying to take the calculator apart in order to fix this problem, but I am unable to take off the foil cover. I have seen and read that there are supposed to be two screws holding the foil cover in place but I don't see any visible screws. Also, in other calculators of this same exact model the foil cover extends further, but in mine almost half of the circuit board is exposed.
Es esta una buena pregunta?
