Can a HOT be shorted open on all 3 legs? I have a Hantarex Polo 25 that is HOT chirping and when I check it with a meter, none of the legs have continutity.
 
A short circuit is the opposite of an open circuit. You cannot have a "shorted open circuit". Are you testing the HOT out of circuit? You'll often get false readings if you don't remove it from the chassis.
 
Sorry for the awkward wording, I shouldn't be allowed to post before 12pm... I did take it out of circuit to test and get nothing between any of the legs.

I have the same monitor with the same chirping symptom that I am currently working on. I replaced the flyback and every electrolytic cap first. My flyback had been "repaired" and had a buttload of silicone globbed all over it. The caps were more preventative but I was hoping that they would solve the problem too. Neither did. From what I have "learned" through hours of searching and reading is that there is probably a short in one of the diodes or poly caps in the vicinity of the HOT. I have written down to check D134 and D135 and C172, C174 and C175. Have you checked the power coming from TP6,7,8,9? I just got my replacement parts in Friday but didn't have time to get to it this weekend. I will let you know what it turned out to be on mine if I get it going.
 
Honestly haven't done a thing other than check the HOT. This was an auction purchase YESTERDAY, that I had jumped into checking out. I did the simple check on the "chirp" and no more, but since it isn't a short, time to check out what you said, and I will report back.
