I recently purchased a Joust machine and my life has gotten about 1000x better because of it. I turned it on a few days ago and heard a high pitched scream from the monitor, when the picture came through it was totally distorted. I've tried looking up this problem else where but do not know the words to use to find an answer. I'd really appreciate if someone could help me diagnose the problem. Here's a link to what it looks and sounds like. https://youtu.be/X0vt3E3R7hE
