Maybe it's already got enough scratches to not make a difference, lol.For the love of your cocktail glass put down a piece of cardboard!
It's not the xy board I can put the xy board in another monitor works fineFrom the chart

Then it's the X/Y board headers themselves on the chassis. Reflow them. Reflowing should be removing the solder, checking the pad for oxidation and adding fresh solder. Use a fiberglass pen. Also, give the headers themselves on the parts side a once over with the fiberglass pen, those might be oxidized as well.It's not the xy board I can put the xy board in another monitor works fine
my earliest K4600 jobs (circa 10 years ago) didn't go very swimmingly with just adding solder to the header pins. in addition I did that process wrong: you want the cards still installed or else the heat will make the pins fall out a bit and they'll sit uneven. I don't totally take the header pin strips out, I don't know if I noted on my site that I work the pins odds and evens (the boards have them conveniently numbered) so that way nothing theoretically will move around.Then it's the X/Y board headers themselves on the chassis.

The issue you described is indicative of those transistors on the X/Y board. If it works in another chassis then the chassis is your problem. And it could be the connections to the cards (very common on K4600).
Good Luck!

Found issue was the deflection coilHas anyone seen this issue with a welsgardner 4600 I've tried 2 xy boards dose the same thing tested the yoke seems to test fine xy boards yes fine in another 4600
Was the yoke it self tried good working one it workedLooks like the yoke wires were mixed up
Interesting.Was the yoke it self tried good working one it worked
