Hello all,
Thank you so much for your help and suggestions.
Yesterday l found a fellow arcade guy local to work on the monitor with me.
We replaced the caps, and also replaced the pots on the monitor. After about 12 hours of being on it's yet to do the "vibrating" as shown in the photo above. The repair guy that worked on it with me said he didn't think it was the caps, but the pots that was causing the issue.
