I went to bed and my TV was working fine, I woke up and the TV has vertical lines going through it! I tried using the netflix and that does the same thing. So I know its not the cable. The other TV works fine. I am hoping that when I turned it off last night something just got hit on a setting, but I have no clue where to begin to fix this... please help! It is a toshiba.

What kind? LCD, analog, how old?

It is a lcd, I am not sure how old it is?

You may try resetting the set back to the manufacturer's original settings and see if that solves your problem. If it does not, then the set is kaput. Refer to your user's manual for how to reset the set. LCD's are basically idiot proof but when something inside goes, then they are done for. Repairs could be more than a new set costs.

I will try that thanks!

Vertical lines could be anything and it could be repairable. What is the model number and can you take a picture of the lines and post it?

It's possible the part could be less than $100 to fix it. It's even possible it could be a matter of re-seating a cable inside the TV.
