KT-2100SF / K1-2-V0 with STK 73410 II Regulator Schematic Needed
I need to locate a schematic for a 19" monitor chassis from a Galaga + Ms-Pacman cocktail machine. The heat sink in the HV section has a label with KT-2100SF on it. The bottom silk screen list it as a K1-2-V0 but my copy of that schematic does not have a STK regulator pack on the primary side.
The unit keeps eating secondary B+ diodes (D605) and it's associated capacitors and resistors. Occasionally it will also eat the STK 73410 II ic and it's surrounding caps and resistors. I need to verify all the parts are the correct values and wattage. The repairs last about a month or two then the parts fail again. I'm starting to suspect I have a bad coil or flyback in the HV circuit as I have completely rebuilt the primary side (aside from the xfmr). I want to verify all of the components have been replaced with the exact original values, so I would like an accurate schematic.
Here's a photo of the chassis:

Any help would be greatly appreciated.
