Yes, the HOT is shorted. I've worked on many Magnavox/Sylvania/Philco NAP sets from this era and most shorted HOT's are caused by loose connections or bad caps. However, I've seen a few with a bad flyback. Unfortunately, the only way to check the flyback is with a piece of equipment called a ringer. Otherwise, your only option is to replace the HOT and see what happens. Before replacing the HOT, resolder the horizontal driver transformer and any power resistors that are 1 watt or more. Also, check for bad caps in the power supply, horizontal drive circuit, and in the HOT collector circuit. These caps can look normal and still be bad.
