As you have ordered a replacement, you could risk a few experimental fixes on the old one. I've used runny epoxy to fill in small cracks of the plastic surface of more modern flybacks. And there's a product called "Corona Dope" I think intended for the purpose of painting old flybacks. That the stuff, when dry, has a higher dielectric constant than air. And not allow arcs to happen. That it wicks itself into the flyback windings to fill air gaps. Presumably the original coatings and insulation has dried out and cracked, creating air gaps. This assumes that there are in fact no shorts.
