You are still making assumptions based on how it looks. That is not the correct way to determine if its the problem. Good luck finding a new one, and if you do hopefully that will be the problem.

It's been said to you before, but I'll say it again:


you need to read some troubleshooting books on TV repair theory, because this NOT the correct way to repair faults.


Just because a flyback melted off its wax doesn't mean it's literally cooked, and a humming sound indicates nothing more than a loose part on the chassis. Sometimes it can mean there's a dead short on the secondary of the power transformer, but I always check for that before I even variac a set. Have you checked for a drive waveform at the horizontal output tube grid yet? Have you checked cathode current? Did you go through the horizontal section setup procedure in Sams? Checked B+ voltages? Ohmed out the flyback windings?

These are just a few of the things I do when servicing a set.
