even though flybacks don't move I've seen it enough times where the solder joints go dry on the flyback pins. if you know how to identify bad solder it will stick out to you. I always remove the old solder and lay down new when I go through any monitor.
in accordance with the K7000 flowchart, you should see what the B+ is as the very first step if you have a monitor that doesn't power up. if it's 160V or 0V will make a big difference. the flowchart will explain this to you.
if you do have a 0V condition I would say the flyback is probably bad. you should inspect for cracks. your approach to making the monitor turn on comes off very strange to me, I've never done that before and know nobody else that has either. so it certainly sounds bad.
if that's over your head though then I don't know, maybe the monitor thing isn't for you. the K7000 is a very ideal model to learn on, I mentioned somewhere recently I think that's how I learned how to read schematics.
my Hakko doesn't like sucking old solder, have to add new solder first.
