The flyback was it an original....? Are you absolutely sure the correct wires
are put in the correct pins...? A mistake in the parts near or connected to the
damper could possibly be giving you bad signals going to the blanking circuit.
Incorrect pins could also be interfering with the field strength in the flyback
during any part of the charge discharge cycle....
If the flyback was a replacement, or even if it was from a parts set, you should
check over each connection with ohm meter, or replacement part notes to be sure
the same pin numbers correspond on both new and old part.
If you have checked the work around the two areas you previously worked
and the wiring is correct, then carefully check the parts and voltages near
the items in yellow on the attachment. And replace the caps in green....
If you have already replaced the caps, and found good continuity or if you have
the entire sams with resistance checks for the coils, then you need to check
those caps to be sure they are correct values and voltage ratings.

as far as checking connections to and from the fly i did that already and the fly was a newer one when i got the set not the original. and i went over everything i did and find nothing. the schematic is alittle different then the one i have as i dont have vert centering on this chassis, maybe the one you have is an RCA. but the green caps you speak of it looks like i replaced them you have listed at the time i was trying to figure out the hv issues.
