If you are lucky, you might just have dislodged the batteries. Verify that contact is made correctly. Then adjust the screen contrast. Turn calculator ON (Just press the ON key once) Press '2nd' button and release it. Press and HOLD the 'UpArrow' key. Keep pressing the arrow key until the screen darkens.
You can try other procedures described on this very website. Look for questions I posted answers to.
If that fails to restore your calculator, you should contact TI at the address [email protected]
