Weird Markings on Screen

I have a TI-83 and there has been a dark spot on my screen for several years and it has not been a problem. Try to use yours for as long as possible unless the screen is unviewable.

I had this problem also and just fixed it. I hit 2nd key...don't hold it, (it should say 2nd in the lower left corner across from the DEG) then click the K button (also the divide key). The arrow and DEG will remain, but do not affect simple math calculations. Hope this helps!

click on the menu button on your screen and click on degauss and will automatically remove the markings

well i think your mp3 has got some sort of a file containing a virus so try format it it should help

1) Ensure the cradle is plugged into an active AC outlet and the LED light on the cradle is on. There is a switch on the bottom of the cradle to control the brightness of the LED, set it to the highest. Try different outlets if needed. Does the LED light turn on and stay on (does not blink)?
ANSWER:
2) Remove the battery. Place the remote on the cradle and check the LCD screen. The LCD screen should display a 'White' screen with possible colors before going off. Try this a few times to confirm behavior. Did the LCD turn on briefly?
ANSWER:
3) Reinsert the Battery. Have you charged the battery for at least 3 hours? If no, please recharge the batteries for at least 3 hours.
4) Did the battery ever boot the remote? If yes, please continue troubleshooting.
ANSWER:
5) Remove the battery. Check the 3 gold contacts on the battery to see if there are markings on all the contacts signifying it was connected correctly to the remote. Did the battery have markings on all 3 contacts?

Hello,
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.

First you're going to want to navigate to the Home icon that is on the main screen by using the arrow keys, then once you press enter you will arrive at a different screen and you will be able to enter numbers and symbols at that screen. once you press the appropriate keys for your math problem you will then want to check over that problem and once it is what you want you will then want to press the enter key. The answer should come up. If you do a division problem though, it will just give you a fraction, to get a decimal answer you will then want to press the green diamond key and then the enter key in one extra keystroke to get your final useful answer.
