Thanks, I'll check the horizontal output transistor.

So far all the seconday diodes are OK, caps, resistors, etc... as well. I've been slowly working my through the board

I figured if that FET went, it took the controller IC with it, so I ordered a couple of those, along with the FET.

The IRFBC40 is rated at 6.2A, but the only thing I can't figure out is what that Termistor might be rated at.

There's a bunch of choices for NTC 10 - 3A, 5A, 6A...
