I finally got back to this & replaced C702/703/704. The buzzing was quieter, but it blew the HOT & fuse again. It did take longer to happen, though.
Continuing along those lines, I picked up replacements for C701. Schematics say that it's a Ceramic 0.1uF 50V. I picked up a 200V also. The cap on the board looks more like a Mylar. Which should I be putting in? (top=mylar, bottom=ceramic)

I fixed my issue with pin 6 of the flyback to ground, the solder connections on the T1,2,3 connector had excess wire and was jumping pin 1 to 3.
I'm back where I started, monitor buzzes a bit, then the hot goes poof again. Have a look at the updated picture of what I have replaced /tested.
Green is tested good, Purple is replaced, Blue has been verified between both new and old parts.
