Out of all the TV's that I've worked on, I too have only seen one bad HOT that wasn't shorted. It was in a late '90's 32" Sony that had no HV. This was a set that I'd already replaced the HOT and power supply parts in, several years earlier. When it lost it's picture, the owner simply gave it to me. Anyway, I checked everything and couldn't find out why I had no HV. Finally, I fired up the scope to discover that I had a proper horizontal drive waveform at the base of the HOT. I replaced the HOT and all was well. The old one simply would not work, despite the fact that it checked good.
