As I understand it, you are simply trying to turn your TI-83 calculator OFF. Press the [2nd] key, then press the [ON] key (its second function is "off"). Sometimes you have to press "off" twice.

By the way, if you just leave it on for a while, it shuts itself off.

(One of the nice things about the TI-83 is that when you turn it back on, it remembers what you were doing on the screen before you shut it off.)

Sorry, but you cannot. That is the cursor, and it is equivalent to the cursor you see on your computer when typing text. You can change the resolution of the screen by pressing 2ND then the up and down keys, but this will change the resolution of EVERYTHING that is on the screen, not just the cursor.

My son's TI-83 calculator screen is very dark. The calculator appears to be working but I can barely read the screen. Any suggestions?

Try adjusting the screen contrast. Turn the calculator on. Press and release the 2ND key, then press and hold the down-arrow key to darken the text. If you go too far, use the 2ND and up-arrow keys to lighten the text.

Is there a way to play games and put in a password on a TI-83 plus?

Yes, there is. There is a program called mirage os and another one but i forgot the name. You should google it to find online. You need to have ti connect which you can get it off the ti website. Well mirage os can have a password by pressing alpha in it. Also in order to have a password to turn it on you would need to go to mirage and then press on and then it should turn off. To program you would need to know assembly or ti basic (they are basically the same language). To start programming he would need to press the prgm button and the options are reached by pressing the prgm button again.

My ti-83 plus has OS problem

That happened to me a few years ago - my friend tried to give me his operating system, and my calculator was all locked up like that for a while. There's some kind of reset code - pressing some buttons while putting a battery in - but it's been a while, so I don't remember which buttons.

2nd MEM RESET DFLTS This should restore your calculator to orriginal default settings. No offense but even the manual does not recommend wiping the memory, i would avoid this step in the future Get the TI-83 for dummies book It really helps d.l.l.
