There's only one terminal on that tube that can harm a meter: the plate. The plate is always the top connector on the tube. Measure the other terminals (the ones on the bottom) and your meter will be fine and you'll know more about why there's no HV.
While it is nice your flyback looks good, looks are not conclusive. I've seen scary ones work fine and really nice ones that are shot.
Also if you are running it for more than 30 seconds after warmup and there's no horizontal osc you can potentially damage both the flyback and H output tube.

Ok, thanks. I've only ranthe TV long enough to check for a picture on the screen, after I saw there wasn't anything on the screen I immediately shut it down.
