Then continuity tested R,G,B,V-SYNC,V-GRND all seem fine to the chassis.
Pulled the chassis, "A" Which is the point that connects to either WIDE or NARROW, I tested continuity over that and wasn't entirely convinced it was good, thought logically that might have been a stress point so resoldered that.
Then I continuity tested the RGB points on CN102 to the neck itself*
Alas though it's still a mess, not syncing, more red now than green
*just realised I didn't continuity test the others to neck so will do that later for good measure.
