part over by V1 where there has to be a rotten nut.....
I'm wondering about C60, & R87, & R14. At this point any Variable Resistors
should be checked from all 3 pins to ground for a possible internal short, not
just checking to be sure they read their rated resistance.... I still did not see
a post about R23 to be sure there is no short to ground from any of it's pins...
Think about that "tin wiskers" stuff inside these pots.....
Any way poor Timmy being pulled in 30 different directions to check this, and
replace that..... I think he needs a beer....... And if he ain't drinking yet
well then he's a strong determined individual!
The other bad bunch-a nuts can be hiding in that V6 area, where this focus
pulse is going - See that pin 3 with 2.5V on it, and with the scope pic of that
450V P-P wave.... No way you going to be able to figure out what should
really be there..... And that little circuit helps that K1 do it's thing, and it's
attached to V1, or did I say that once already.....
