Question about Texas Instruments TI-83 Plus Calculator

1 Answer

Random characters lines and pixels

I've never dropped my 83 but the last time I turned it on, it displays random characters and pixel sometimes short lines. I can still perform calculations, but they are mostly obscured by these symbols, the same applies to nearly all aspects of the calculator including the graphing screen, programs, and apps.

Re: 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.

When I turn on the calculator, I get a screen full of random black pixels. The AAA's and the lithium batteries are both good. Nothing I do will change the screen, except turning the calculator off.

Try to reboot your calculator to see if it helps by doing this:
*Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. *
Let me know if it helps or not.

First time used in months

Check the batteries polarity.
Perhaps it needs a "reset", some calcs do have a "button" therefor, some do if you press the start button for some seconds.
Try to leave the calc overnight without any batt. inside.

Characters & menus display incorrectly

It is a display driver issue. You can buy a new one or get it repaired ($100).

Ti83 Plus

e0df163.jpg does it look something like the example I gave? Anyways, I don't think that it can be fixed. and you can either:
A.) have the screen fixed (approx. $100)
B.) buy a new calculator (approx. $85)
( the monetary figures are approxamate and should not be taken literally, the $85 is at least what I last saw one for @ a Wal-Mart)

TI-83 LCD Screen Problem

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

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.
