When I turn on my Ti-86, there are two lines across the screen

The lines are about 1/3 the way from the top. The calculator will not function except it will turn off and on.

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!

Blank lines across the screen of a TI-86 graphing calculator


Try this, hook up new battery and go to MODE and darken and lighten the screen.. do it ten to fifteen times. if that doesn't help, try hook up most left and most right's battery terminal to a DC supply at 4.5V. dont go above 4.5 it will fry your calc (it is design to handle 3V). now you are forcing extra juice into the dead LCD screen lines... and reapeat the MODE + darken trick. I fixed mine like that! Works! and remeber to leave it completely black(darkest) for a while to keep that dead line alive!

Adjusting the ti-86 screen


First make sure the cable at the top of the screen is not pealing off near the edge, on the inside of the calcualtor. You may need to peal it off and reattach it, align the strip with the metal coating strips on the glass, you will see the strips when viewing the glass at an angle, but that is risky because you may not be able to reattach it. Next check the small square that says "8" on the back of the display board, you will see minature wires, make sure all the wires are lined up properly, if not thats a factory defect. Goodluck.

Most likely you're trying to graph a function while you have the stat plot turned on. Turn off the stat plot and try it again.

Broken screen


I don't know that you can replace the screen, but you can download a TI emulator that will let you load you 86's ROM onto your computer and use it on your computer screen.

Hi I got a problem with Ti-86 which is a line of the screen pixel missing. I tried to increase and decrease the intensity of the screen (2nd and up, down). Also tried to go to MODE function. I have tried those for several times. It works great. The line of those missing screen pixel came back. I don't know why. Just try it.
