You ran the 0v-9v volt sweep at test point A to show that it's not an AGC problem with the video, otherwise you would have seen a reaction on the screen as the voltage was changed at point A, and the gain was forced to change.
You said that you unhooked C59/C60 and there was no change in the heating of L42, so unless perhaps there is a fault in the wires between C59/C60 and the area of the flyback transformer /L42, the problem is still in the area of the FBT.
R13 alters the bias on pin 7 of V6 and R14 alters the bias on pin 6 V6, the balance of the 2 will alter the voltage on pin 3.
What you uncovered the other week, you do have an IF fault, regardless of if AGC is working correctly or not, 3rd IF is working, direct into 2nd IF works, but 1st does not, including L4 .
This has yet to be debugged.
