So a few days ago I bought a ti 83 and it wasn’t working I tried every thing eventually I got it to work but o through Xton didn’t work and all typed comma. It doesn’t turn on I’ve tried everything can I please get help?
The key matrix sounds broken. You'll have to take it apart and find the broken circuit traces.
Administrator's note: four posts edited together into one:

I’ve taken it apart and nothing looks wrong when I get home I will take it apart and send you a picture. Ok?

Oh and when I Try to turn it on it flashes black screen and turns off

I’ve found when I pres on and then on again it does nothing but when I press 2nd on so turning it of then pressing on it flashes black again

I will be home around 4:30 central
Did liquid ever get on your calculator? Have the batteries ever corroded inside? Check the backup battery as well.

Do you have a multimeter? It's going to be basically impossible to figure out what exactly is broken unless you can spot the problem visually.
I do have a multi meter I took it apart it turned on at one point I saw it I don’t think it ever got wet internally but it did externally

Edit: These are pictures of my calculator:

This symptom often is due to a failure of the coarse ribbon cable connecting the LCD and the calculator's mainboard: you can try to narrow down the problem by using a link cable (if this is a TI-83 Plus, the USB-to-2.5mm cord called the SilverLink) to see if TI Connect can view the contents of the calculator. If so, it's just an LCD problem; if not, it's likely a more pervasive and serious problem.
So if it is should I just get rid of it?

It's entirely up to you; I would certainly suggest trying to repair it, but everyone has a different level of skill (and patience) for repairs. Many of the things we've been discussing in this thread are fixable:

Did you intend to post this in this topic, or did you mean to post it in your topic asking what TI calculator you should buy?
I mean no but I was just saying
