Larry, I don't have the exact location, but I had the same problem on a
CS3131 and there is a small steering diode on that line that opens and also
causes this. I keep thinking it's D4A1 or 4A2 but it's just a 1n4148 type.

Model CK3136R. R4H1 & R4H4 keep burning up & Q4A1 transistor keep shorting
after a short time of power on. I have no horiz output either, but have
normal B+ 140V. I have replaced the vertical output IC & the other parts
twice.
