what up guys so got a whole mess of calculators here they're all tea eyes and one of them isn't coming on now they're all solar panel so you would think with lye it would come on so it looks like it's this one that one's working that one's working so we're gonna take a look at how to troubleshoot and fix this TI 30 X 2 calculator now it's not coming on nothing's working of course so what I'm gonna do is I'm gonna take the thing apart and see if we can't figure out what the heck's going on just because it is solar panel doesn't always mean there's not a battery in it as well so just grab a little screwdriver and there's gonna be some screws in here looks like right here of course you want to screw counterclockwise looks like a couple more at the top and then the thing is probably together pretty tight you probably got to get something in there and wedge it being careful of course now goe
