K7100 complete vertical collapse - anything else to check?
Spent all day researching and working on this thing:
27V on IC3 pin #6
Swapped out IC2 and IC3
C22, C50 are good
R80, 81, 82, 83, 91, 101 are good
D13, D25 are good
Q7 is good
Continuity from IC2 to Y and G vertical coil pins
Swapped out remote control board
Tried another tube/yoke
Cap kit installed a month ago
C51 reads .6uf with ESR of 5.3ohms. Mentioning this because I don't know what is an acceptable ESR on a tantalum cap.
The monitor was fine for months but went south when cabinet was moved to a friends house. Anything else to check?
