Thanks oldturkey03 for getting back to me. I am really interested in fixing the unit as it makes good prints and a new LED one is $4,000.
I think my first question is how do I test the board to see which components are not working correctly? I have asked Beseler for the single line diagram, and I have also found this one on the web (not sure if it is the same for my unit, see attached.)

Second, if it is a Vacto Opto Coupler, how do I find an equivalent part that will do the same thing?
If I can’t, I would like to figure out how to connect a external voltage controller to the unit and have it operate the system, or build a new one to replace this.
I had electronics a long time ago, so I am reaching back trying to remember how to do all this testing and replacement.
Best,
David
