    I have the same problem. I can't use any of the functions because I can't read the menus at the bottom.

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.

Every time you change batteries this will happen to you. First press 2nd then press and hold the down arrow. Hold until their is no black in the background but you can still see the numbers on the screen.

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.

Texas instruments ti-86 screen problem

The TI-86 uses a very small, very thin ribbon cable to connect the display board to the LCD. The cable is about 2.5 " wide and about 4" long, and is only slightly thicker than a piece of paper but has about 40+ leads buried inside. Over time the leads will break at the folds (there are at least two folds in this cable to fit it down inside the case). There is no cheap solution to fix this problem. You might have some "Mr. Fix-it" try to fix it, but he will tell you to throw it away after he renders it completely inoperable. The calculator uses two Torx bit screws at the bottom of the case (T-6 size) so you will have to get the correct screwdriver to open the case. Save your money, sanity and time and use it till you can't stand the missing lines and throw it out. Even the data cable looks like it is glued down so if it lifts off after being cooked or frozen a couple of dozen times in the back of your car you can't fix this.

Random characters lines and pixels

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.) It works great, and the calculator is fine unless you leave it unused for a month or so. A similar solution may work for you.
