Question about Texas Instruments TI-84 Plus Calculator
All of a sudden, the numbers on the LCD screen are very, very pale. I have tried looking in the manual and online both, and I've read that you need to press the 2nd key and the up botton in order to make it darker, and I have tried this and there is no change. I have also changed the batteries, and there was no change again. What could this be? Thank you!
Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.
