Depending on how the STR is shorted, I would the think the set would still
run. Assuming the AC line voltage is reduced enough to achieve 130VDC at the
output of the regulator. This is a simple linear regulator and easily
bypassed.

A "Shorted" STR certainly would not point me in he direction of the flyback.
Maybe if you had a shorted horizontal output transistor, I might feel
inclined to agree with you. But certainly not on 1 shorted part and
intestinal feelings......
