I have an arc in the yoke in my CRT, the flyback is bad but still creates energy.........I have been told this is terminal because it indicates there is a crack somewhere that had allowed oxygen in the tube hence the creation of the arc........is this correct?

I was hoping that using a rejuvenator, the short correction portion this could be fixed........

Do you mean to say neck instead of yoke?

The yoke is the coils of wire around the neck.

Arcing inside the tube would be gas and can not be fixed without rebuilding the tube.

I remember an Admiral that kept eating flybacks. It turned out to be a high voltage short in the yoke. That was fixed by replacing both yoke and fly at the same time. The tiniest wisp of smoke was the only clue. Craig
