Try a hard reset. Press and hold the 2ND, left-arrow, and right-arrow keys, then press and release the ON key. Be aware that this will clear all RAM.

Blank screen will no com


TI calculators have an annoying habit of dimming the screen, especially when the batteries are changed, so that it appears as if the calculator isn't turning on. 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. Does it?

My texas instrument TI 83 plus graphing calculator will not turn on. Put new batteries in and still wont work. What could be the 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.
