Isn't that vertical IC feed with dual V+ ,one from the fly.
Diode and small resistor I got caught once now I change em when I see em.
Dont even check them just replace them.

26V and 13V comes from fly via two diodes. Does this help?

Vertical only get one feed, 26V, the 13V is fed through yoke winding
to the vertical IC output as midpoint between 26V and ground. Been
this way since CTC17x even eariler through ATC113.

To others, The only one SMD is capacitor for vertical circuit itself,
already replaced with another and through cleaning. The other SMD
items is only for feedback pulses back to the chassis.

I'm very certain that coolant did not leak onto component side because
the holes were shut with original solder and did careful check just in
case. Previous one had few open holes and got some on solder side.

Washing goes like this: HOT tap water (nearly 70C) TSP then rinse then
hot water & oxiclean, rinse throughly, then alochol drenching for
assisting drying. Then dried carefully with heat gun. Yes did both
sides. Done two before with success. That's for only 4" band along
front area where coolant tend to hit anywhere; audio amp, micro,
pincushion and vertical circuits.
