T1 83 problems with screen

When I turn on my T1 83 Plus the screen is black but there is a line near the top of the top of the LCD screen. I tried replacing all batteries but line remains.

    I have the exact same problem, darker screen outline tells me it's 'on', but changing the batteries does nothing except that the one character at the top is no longer present after the battery change, just the blank screen and nothing on the unit I can't try the 'reset' instructions from another post. Any insight would be greatly appreicated as my warranty is either out or just about out any day now.

    Thank you

What you do is hit 2nd button and the down arrow and hold and your screen should eventually lighten up!!

I'm using a TI-83 Plus calculator. Halfway through my screen there is a straight line preventing me from using the top half of the screen. No matter what I do I can only use the bottom half. Is there...

You've got the split-screen turned on. To turn it off, press MODE to open the mode screen. Use the arrow-keys to move to the second-to-the-last line, highlight "FULL," and press ENTER. Press 2ND [QUIT] to exit the mode screen.

TI-83 Plus Problem

Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!

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.

TI-83 LCD Screen Problem

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.
