basically you have a stat plot on so to turn it off, press 2nd and then the Y= button to get to "Stat Plot"
one of them is turned on so press enter and select OFF. this should fix the problem!

How do I put in Sin^2
?
sin(x)^2
sin^2 and its kkn are an unusual notation, compared with other functions. For example, you don't write log^2(x) but instead log(x)^2.

Black screen with full batteries
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. 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.
If that doesn't work, post a comment here and we'll go on to the next step.

Convert $8 000 000 per mile to $ per kilometer
There are 1.609344 km in a mile. So, the following statement is true:
$8 000 000 = 1.609344km
Now bring it down to One km, rather than one and a decimal by dividing both sides of the equation by 1.609344.
8 000 000/1.609344 = 1km.
You wind up with the following:
$4 970 969.5378986717569394734749065 / 1km.
(obviously, round it to a normal dollar figure, rather than to hundredths of thousandths of cents)
You wind up with $4 970 969. 54 per kilometer.

When it turns on there
Having gone over half a year without a response to my query, I assume my suggestion to adjust the screen contrast solved the problem.

Line across the screen
If it's just a single line then it sounds like that the screen is not connected probably or is shot...
if it's more of a "flurry" or snow... then you can connect to another unit via the I/O cable or usb if your model has it, and use the "send OS" command to start from scratch and lose all data but have a working calculator.
