I actually put a bit of dielectric grease around the opening of the HT cable and popped the rubber cap back over, seems to have solved it for now. I may 3d print a 4 part assembly to encase it since PLA has some pretty impressive insulating properties, at least when printed with 100% infill at the right thickness.

I've also made some dynamic convergence adjustments which I think have solved moat of the convergence and bowing issues.. and created a new one at the very bottom where it bows out at the sides. The service menu adjustments don't help so I guess I'll be trying again. What a pain it was though!
