So, I've got a chance
to try to repair this game.
I used to fix arcade games all the time at a theme park, but they were different, more recent makes (usually.) The owner says that the lights turn on, but there is no sound, the screen is blank.
Also, I have 2 years of engineering school (including some circuit analysis), a ton of experience fixing claw machines, and a bit of experience fixing other machines. Do you have any advice for approaching this problem?
