20 Most Recent Texas Instruments TI-84 Plus CE Graphing Calculator Questions & Answers

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.

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.

Try the Ti site. I doubt it is still available as it is a very old machine.

Are the batteries fresh? Try putting new ones in. If that doesn't help then your LCD display is probably damaged and it will probably get worse. Can it be fixed...probably, but what's worth to you? If the calculator is only worth $50 (IDK?) but they want $100 to fix it at an electronics repair shop...is it worth it?
