K7000 Vertical Circuit Photo Found

follow pin 4 off the flyback, +24V, R91 is the fusible resistor where if there's any shorts on that circuit, it will open up to prevent any further damage. D13 is after R91, if D13 is shorted then assuredly R91 will go open. I had one where R92 was also bad, that apparently provides +12V to the LA7823 chip, so I suppose that would make sense why I had vertical collapse. I suppose D25 could be another point of failure, and C42 100 uf/35V charge cap (this turns that +24V into about 50V which IC3 needs to achieve full vertical deflection. if you use your meter on diode test you should be able to touch red probe to ground (the heatsink) and black probe to each of the vertical IC pins to see if there's shorts/opens. in fact if you want to do humanity a favor, make note of the readings from a good vertical IC, then you can compare your vertical collapse ones to it later.
