Trouble with an HY-5500 CRT -- HV supply not working

[user1]

Why did this thread abruptly stop? Is there something irreparably wrong with the CRT?

For example, in my case... Too busy last times... is easy to miss to respond to some topic/thread, and then this vanishes from the list, unless the ones can respond to it manually subscribe to it, or maintain the thread windown open (I noted that the Videokarma don't automatically subscribe to the thread when one post something). So this ends lost, until the therad owner quests about/bump it.

If you have a full raster when you short the PSU transistor, the CRT have to be good, in principle... unless it have a yoke problem, but then it will distorts a lot the image or shrinks it.
