Problem with my TI-83 plus silver ed.RIgthside screen doesnt work


Hello,
Here is a horizontaly split sceen. Lower oart is normal working scree. The upper part is for the gpahic screen, but I entered no function to plot. In the image the focus is onthe graph screen, hence no blinking cursor in lower (normal entry) screen.

Here is a vertically split screen

All these are artificially created behaviors. That is why we often suggest to reset ALL RAM or reset the defaults.

Hope it helps.

TI- 83 Plus Silver Edition problem


Many TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on at all. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
