I picked up a Tetris cabinet locally for 75 bucks. Supposedly, it was working until 2 weeks ago, but when it was moved into storage, the monitor dislodged and fell off its shelf. Since then, it hasn't worked.
I am thinking that when the monitor fell, it pulled a wire or two. Unfortunately, I couldn't find anything obviously wrong. But with my limited skills, that's not surprising.

The cab powers up, I hear the monitor power up (ie hear static building up), and the game plays... but no video.
I have attached a bunch of pictures. Hopefully someone sees something wrong.
Thanks for the help.
