Question about Texas Instruments TI-89 Calculator
When ever i turn on the calculator, it has a big black screen on it so i can't see anything.
Try adjusting the contrast setting:
1) Press the green diamond key (under the 2nd key)
2) Press the minus key to lighten, and the plus key to darken.
3) Repeat steps 1 and 2 and until the display gets to where you like it.
