Texas Instruments Office Equipment & Supplies - Answered Questions & Fixed Issues

I have the exact same problem (just happended recently) with my TI-5045 II after 25 years of good service. My solution? I just bought another model: Sharp EL-1801V at Stapels for about $31.00. To get the old one fixed will probably cost me $25.00-30.00 just to diagnose, plus shipping and parts and labor. And that assumes I can find a shop to do it, or that TI still stocks the part(s) gone bad. Same old problem with all technology.

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.

Hi,
It has two batteries CR2032. They should not be removed at the same time. There must always be one battery in the calculator. The calculator should be turned OFF when changing batteries.

Often after you change batteries the screen contrast may be too light and you cannot see anything. The contrast can be adjusted (lightened or darkened). As you adjust the contrast setting,a highlighted number in the upper right corner changes to indicate the current contrast setting; 0 is the lightest, and 9 is the darkest.
To adjust the display contrast:
1. Press and release the [2nd] key.
2. Use one of two keys: (UpArrow or DownArrow)
--- To increase the contrast (darken), press and hold [UpArrow]
---To decrease the contrast (lighten), press and hold DownArrow

Hope it helps.
Thank you for using FixYa.

Wow, I'm in the exact same situation. I've had my trusty TI for 6 years and now all of a sudden this gibberish is on the screen. You're right, there is absolutely nothing you can do to fix it. Guess we'll have to bite the bullet and buy a new one. 

Milliliter is a unit of volume, milligram is a unit of mass (or weight). There is no direct conversion between them. 5 mg of water occupies 5 ml. 5 mg of gold occupies about about a quarter of a ml.

One millileter is about 0.033814 fluid ounces, so to convert ml to fl oz multiply by 0.033814. To convert the other way, divide by 0.033814

Refer to page no 13 of user manual of calculator. (TI-30XS / TI-30XB MultiView™ Guidebook - Texas Instruments - US and Canada) It will solve your problem.

Your right you should be in degree mode. However, my guess is you are somehow entering in cot wrong in your calc. Recall cot = 1/tan! In your graphing calculator enter: 35(1/tan(61) = 19.4. Hope this helped!

DOMAIN ERROR: - You specified an argument to a function or instruction outside the valid range. This error is not returned during graphing. The TI-84 Plus allows for undefined values on a graph. - You attempted a logarithmic or power regression with a LX or an exponential or power regression with a LY. - You attempted to compute GPrn( or GInt( with pmt2 < pmt1.

The simplest way would be to create a table where each x-value has a y-value that is the residual at the corresponding x. With a 2-list data set you can plot you residual plot.
