It sounds like you have a problem with the screen control which is usually part of the flyback transformer. If the screen voltage goes too high the picture tube current also goes too high and causes the set to go into shut down.. Now that it won't come on at all, I'd say that the flyback and horizontal output transistor have shorted. You'd probably ahve to take it to the shop and have it checked if you're not a tv repairman.
