Re: TI-83 LCD Screen Problem

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

I have an old TI-83 and there are vertical lines across the screen which have dead pixels, I assume. Can this be repaired or do I have to buy a new one.

While someone skilled in electronics may be able to fix it with enough time, the cost in time and labor would far outweigh the cost of a new calculator.

TI-83 Plus Went Dead

Has it been dropped recently? The screen may have cracked from impact. Press the Reset button on the back using a ball point pen.

Dead Pixels?

I've heard that if you press on the dead pixels with your finger for a few seconds, sometimes they go away. I've also heard if you get a damp cloth, turn the screen off, press it on the dead pixels, turn the thing on, and remove the cloth, they might also go away.

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.
