Hello, First of all no; it is not normal for your screen to be black. How can you enjoy the wonderfulness that is Ti with a dark screen. For the solution; it sounds like your contrast needs to be adjusted. Hold 2nd and down. The screen should lighten. If it reaches about where you can not see the cursor, then press 2nd and up and this will darken it. Hope this helps; Happy Calculating

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.

Still dark screen after trying to hold down the second key and then the down arrow


I got frustrated with mine so I started to press the 2nd, then releasing, then hitting the down arrow, and back and forth... and it worked! Please try this instead, it worked and I've been trying to use the hold and press this and that, but the alternating worked better!

Take out one battery. While holding the "On" button, put the battery back in. It may take more than one attempt, but it should start working again. Tell me how it works out, and hope this helps!

My screen is black after putting in new batteries in my TI-86


Adjust the contrast. Turn the calculator on. Press and release the 2nd key. Press and hold the down-arrow key until the screen lightens. If you go too far, repeat the process using the up-arrow key instead of the down-arrow.

The screen is black when I turn it on. I've replaced the batteries and no change. I try to change the contrast and nothing happens. It is a couple years old, but I should still work.


Hi,
Check that the terminals in the battery compartment are clean and shiny. Remove any powder left after battery leakage. Insert fresh batteries in calculator. Make sure you respect the polarity diagram. +-+- (Many malfunctions come from incorrectly placed batteries).

To adjust the screen: Darken or lighten display

To darken screen
Press [2nd] key and release it.
Press and hold [UpArrow] until screen is dark enough.

To lighten screen
Press [2nd] key and release it.
Press and hold [DownArrow] until screen is light enough.

Hope it helps.

Black screen


Try adjusting the contrast. It may be too dark. Turn the calculator on press the 2nd key and the down arrow. This is how to adjust the contrast and will lighten the screen. You can darken the screen the same way, but use the up arrow instead.

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!
