First let me say, I'm no monitor guru but have done a few cap kits that worked out. I'm working on a WG K4600. The pictures below is what it looked like Before and After the cap . No Change! I don't know how to describe it. It is way to narrow and part of it is doubled.I and reflowing pins and connector housing. Buzzed out board connection point thru the connectors. B+ is 129. HOT checked good replaced anyway. I did the full cap kit . With filter cap and C621 axle cap. Neither the horizontal width coil or horizontal center pot(checked) has any effect. The Hor. width coil physically looks good, not broke ,center intact. I do notice that it never get warm if that means anything. Any Ideas?

never replace good parts. HOTs either work or they don't, they don't "wear out". your width issue I can't really contribute much, cause I don't know the 4600s circuits very well. I would imagine it's probably like a poly cap or something that isn't making connection.

the double image thing, the card with all the adjustments on it, there's a silver box with a red pot inside it. try adjusting this. be careful, like width coils, they can just break.

OK I adjusted that and it took care of the width and doubling. I now have waviness along the top. I've tried the other adjustment will no difference. The waviness stays even if I make the screen vertically smaller. Do you think that's a cap problem. I'm going to recheck everything for cold/cracked soldier joint and broken traces.
