Ok; short version of the story....while hooking up the 6th button to my small naomi cab so my wife can play MVC2, my friggin kitten jumps into the open cabinet(while it's off) and after she jumps out, monitor does nothing. Totally dead-no power, no nothing. Great!
So, after mucking about a while and ordering a repair kit, I suddenly discover that, while jumping out, the kitten must have brushed up against the neck card and loosened it a tiny bit....maybe it was the angle of my light, but just happened to notice as I was getting ready to discharge that there was a tiny amount of silver showing where the neck card plugs into the tube(i.e. you could barely see the pins in between)....
So I push on it and it plugs all the way back in....and I think no way! It couldn't be....
Turn on the power and the monitor fired right back up good as new... (meanwhile got the repair kit later and put it on anyhoo, just because I had ordered it and all)...
So my question is, what else can happen in this type of situation? Are the symptoms random, depending on what pins are exposed? Could this cause a symptom that would resemble something more serious(like HOT being blown,etc)? Or would it simply be a case of, as in my nanao monitor, if they aren't plugged good it simply doesn't turn on at all?
Thanks for any and all clarifications!

the highest voltage on the pins will be the focus voltage . (6kv -12kv +/- )
minor arcing could occur if pulled off just enough . generally, a disconnected crt will NOT cause a no pwr symptom
as hv and sweep will be present . just no pic/dark filaments.
there are some 32"+ tv's out there that will take out the hot under that condition !
have not yet encountered the same in a game monitor ..
