Try to reset everything to see if that helps. If it doesn't , you can try to upgrade your operating system on the calculator to see if that helps to make it go away.
If that doesn't help try this:
"Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message."
Let me know how it goes.

My TI 86 is 6 years old and I have taken careof it well.


Try pressing (lightly) on the bottom border below the screen. If there is no change, try the top. If there is still no change, the power for your LCD may have become disconnected or shorted. There are external displays for these calculators intended for overhead projectors. If your school has one, you could try hooking it up to make sure the calculator itself still works.

In either case, it would be better to purchase a new calculator.

Good Luck!

My screen has a horizontal line across the screen


Make the calculator perform a self test: Part of the test is the display of some line patterns. You will be able to see if something is wrong with the screen.

TO PERFORM A SELF TEST (No I am not shouting, but I cannot use Bold fonts nor underlined)
  1. Turn calculator ON
  2. Press and HOLD the ON key
  3. Press the "E" key , the key with an E to its right
  4. Release the ON key
  5. Tests will be performed cyclically until you execute a SYSTEM HALT
TO PERFORM A SYSTEM HALT
  1. Press and HOLD the ON key
  2. Press the and release the "C" key key with a "C" to its right.
  3. Release the ON key
  4. You should see the empty stack.
If you need to repair it, google FixThatCalc.
Good luck.

My screen on my t1-83 has gone really dark and i don't know how to make it brighter


Hi,

This means both your Xscl and Yscl values are too small. Fix this on the WINDOW screen, as explained under My screen is covered with horizontal or vertical lines.

Thanks

Fame !

Casio fx-570ES calculator inner screen cracked


the difficulty of finding a replacement LCD maybe would cost more than having a new one. and even if can find a replacement, installing it would again be very difficult! circuit to LCD connector is fixed, once remove, there'll be no guarantee that it would still function normally! try to disassemble your calculator and see if you can manage to disconnect and reconnect the LCD itself!

Screen not displaying whole letters because of horizontal and vertical lines


I've had the same problem. A temporary fix that I have found is to turn up the contrast all the way (press [2nd] then hold down the up arrow) until the screen becomes mostly black. Then turn the contrast back down (press [2nd] then hold down the down arrow) until it is at a normal level. If you can get rid of all the white lines when you turn up the contrast the screen will be back to normal. Unfortunately this does not permanently fix the problem because I cannot get rid of all the lines and it seems to be getting progressively worse each time it start up the calculator.

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


I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.

Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.
