Either way I'll be swearing.

Haha. I find that when working on monitors, cuss-words come out like you wouldn't believe. Whether it's from exhilaration from fixing an issue, or pain as the anode snaps at you because you forgot to discharge again. Heh.
I'm more fond of the "happy because I fixed it" swearing.![]()
If you zapped by the anode while it's on than you can't swear. You get all locked up that's the only instance where you don't swear.
videos uploading later tonight. Spoiler I freaking fixed it! It started right up image fills the screen perfect. The new flyback sounds very quiet. Huge thanks to sjlewis for selling me the chassis and security0001 for excellent service to the community and the flyback. I'm going to modify the 4700 frame right now but I'm just over the moon because that damn 13" tube works with the 19" chassis.
Sweet! Nice job man!
I just can't believe a reflow and a flyback fixed this thing. It would've blown sparks had I tried it before replacing the flyback.

Orange is made up of 2 parts red light to 1 part green light, so test those two colors independently (specifically red at full brightness and green at half brightness)
An expert will hopefully chime in, but you may have r, g, and b drive and r, g, b cutoff adjustments, or you may have one of the three missing (like green), in which case you have to use the overall screen adjustments (brightness) and the r and b to balance them out
You have a test pattern generator or a game with good test mode color screens for making adjustments?
If you are getting yellow where you expect orange the green is too high for whatever reason, if you're getting red the green is too low
do you have a TPG so you can isolate the colors and see if one or any may be weak?
do you have any of the newer game pcb's with the color bar test screen and use that. with 6 transistors and an IC controlling the colors (assuming there isn't a tube issue) you really need a way to visually see them separate which would make this issue so much easier to fix instead of swapping and guessing.
I have a centipede which has the closest thing to color bars from what I know. I dont own any games that do color bars sadly.
Edit: after much thinking it seems the image itself is getting no green. If I turn the green up the green goes up on the screen not the image. With the red it's weird because I try turning it all the way up and nothing really happens like the screen goes all red but there is no green in pacman or his ghosts. I'm thinking bad green transistor or input header solder not sure tbh.
