I got a used calculator online and when I opened it to access it, it was not working at all, no matter what button I press it would not do anything. Can somebody help me? Sad Sad Sad
Does it have batteries in it or are the batteries dead? I guess I'm not an expert on calculators (like other people on this site) but I would check that first. I hope you can get it fixed.
Also welcome to Cemetech!
So its a TI-84+SE?

Standard things to check are: fresh batteries, contrast level (try to turn it on then press 2nd followed by the UP arrow a few times), connecting via USB to a PC to see if its recognised, Hold CLEAR while removing and replacing a battery to name a few.
