Hi and welcome dude,
The lines you describe sound like flyback lines that might be caused by the screen voltage being set too high. If the lines do not look like pixellated graphics garbage that is.
It also sounds like the game is not booting, so you might have two problems on your hands.
Does the exact thing happen _without_ the board connected? If so, you need to adress the board issue first, and when that's fixed you need to look into the monitor issue.
