In many of these sets, a flyback failure would short the HOT, which would then short the B+ regulator. If the B+ is too high and you keep running the set, you may cause excessive X-radiation, as well as ruin the new flyback, the CRT, or other parts.

I had replaced that part as well (STR3130)
Anyone have a SAMS or similar manual on this set I can thumb through?
