TI-83 Plus screen problem

I was using my calculator to work on problems in class when all of a sudden, strange symbols and numbers started showing up on the screen. It looks like some of the stuff I want shows up, but it is impossible to see it because there are lines and shapes and blank spots obscuring it. When I hit the clear key, some things disappear, but others take their place. What is going on and is there an easy fix? Two weeks ago I wanted to switch my ti-83+ on, but instead of the curser 3 horizontal lines appeared. As the batteries were 4 years old, I though I could solve this problem by changing them. It did until yesterday! Now all I can see are these lines. They even change when I'm typing something in, sometimes the display becomes completly black. What can I do? I really need my ti for uni

SOURCE: Horizontal lines obstructing the second half of the ti 83 calculator screen, anyone know repair tips?

I've had a similar problem in the past with my TI-86. It still happens sometimes when I don't use it for a while. To fix it, all I did was set the screen to its darkest setting and left it on for 10 minutes (keep it from turning itself off, by pushing buttons every few minutes.) One time it was so severe that I had to do it for about 15-20 minutes. It works great, and the calculator is fine unless you leave it unused for a month or so. One thing that I also found helps is if you type several numbers or something to fill up the screen completely and just use the up/down and left/right arrow keys to keep the calc from shutting off. A similar solution may work for you.

That means that you know your calc crashed. This can be caused by taking out the batteries durring running time, happened just randomly. Well nothing to fear just press clear and it should go away but if it stays on that screen you have problems and is best to try some of these methods. Take out all the bateries and press and hold the on button for 30 seconds. Put the batteries back in and it should have reset. Warning you should archive everything incase this happens. To archive go to 2nd mem and hit enter to put a astrick next to the app (meaning archived)

SOURCE: TI-83 screen is black

The "color" on your screen reset to dark. You can adjust it by pressing "2nd" and the "up" arrow (or "2nd" and "down" arrow) repeatedly.

TI-83 have adjusted the brightness but can't type or see flashing indicator

If the screen is not busted, adjust the contrast without going all the way to totally dark or to totally blank. Calculators do occasionally become unusable (old age, mishandling).

Strange markings on the screen, does not respond correctly

Since I do not see the kind of screen you have,

1. I surmise (maybe wrongly) that the split screen is activated.
Press [MODE]. Use [DownArrow] to scroll to where is says Full Horiz G-T. Highlight FULL and [ENTER] Then [2nd][QUIT].
If that does not solve the problem
[2nd][MEM] [7:Reset][2:defaults][2:Reset]

2. An application may be running: Press [ON] button several times to interrupt it. Then clear screen

Hope it helps.
