Hi,
Looking for some pointers on the above mentioned monitor with a permanent barrel distortion.
System has been re-capped, new flyback and new HOT. All works well except for the permanent barrel distortion. Pin cushion control will not pinch the center, only aggravates barrel distortion. Phase control does not shift position as manual suggests, only gives slight illusion of "tilting" top of screen.
Vertical and horizontal position and size adjust correctly, so I believe all is well in deflection land.
Since the vertical deflection is OK I assume the input to the pin cushion board should be fine. So I am pondering the NPN and resistor on the output that modulate the horizontal signal.
Appreciate any clues and pointers - figured someone might have bumped into this one before.
Thanks - been a long time reader of the forum and have appreciated the help you have supplied.
