[NEED HELP] iPad terrible! Black screen etc (FIX?)

[iiaMHulkzX]

Stupiddly i jailbroke my 4.2.1 iPad with redsn0w tethered and now the screen is REALLY dim and it doesn't respond to my finger. I know it turns on as i can see the lock screen.

If there isn't a way to fix it my self i will go to the Apple store but for now does anyone know how i can untether it so it might fix it or another solution to sort out this problem.

If someone helps me there will be a BIG thanks involved.
