Those are a bunch of scans of the schematics that came with the tvs I posted there.
You would think shunting the fly would cause more heat and it may, but keep in mind the failure mode of the flybacks. Its arcing from the top of the doughnut to the bottom and its caused by high voltage breakdown. I have disassembled and re waxed and repaired a few of these. Trust me when I say shunt it.
If you want to lower overall heat, use the high line voltage tap on the power transformer. That will lower the headroom on the high voltage and increase the life of everything in the set big time.
Ill look and see if I have the full service manual on the 15.
