I really could use some help. I am just getting into collecting video games and I picked up a galaxian. When I turn it on it plays fine except for the screen. Each row of ships has a solid colored bar running Horizontally across the screen , each row of ships is a different color and when a ship comes down it has a colored block around it. This is true for my ship. The bottom of the screen has a red thick line that runs Hor. as well. I have no experience with games on a tech level and wondered if someone might be able to turn me in the right direction. I would really appreciate input/advice. Thank you
