hey everyone, this issue may have been answered before but im not having any luck finding the solution. my father had a cosmic avenger game he bought long ago from an arcade and he has loved playing it. the issue is when he turned it on to play it one day he had black lines to the left of the screen that change in side and shape as the game is playing but they don't move from those spots. i did a visual check of the boards and i didnt see any blown caps or any obvious shorts. i repair newer arcade games at my work but these classic games are a breed of there own that i don't know how to fix. ill leave a link to a drop box with pictures of the screen. thanks
