K7201 flyback and B+

your chassis looks like it has a transformer on it, you good fam

His 7200 has a transformer on it. He hasn't shown a pic of his 7900 that's the one in question about the ISO.
 
I put the original chassis back in, took out the video cable to test continuity and saw the white sync wire was slightly pulled from the molex connector. I pushed it back in and got this >_> I feel silly now.

Now to let it warm up and adjust the colors

pics of the blah screen.

the latest pic you posted indicates you only have green.
do you have red and blue??

you can use my video to help you, that chassis will adjust almost like a K7000.
skip to 18:00

Attached is a picture of it now and when I first got it. The flyback was arching that's why I did all the work, I could have lived with it otherwise. I can turn the adjustments on the neck board up and see the blue and red washed out but I can't get the picture better than it is.

When adjusting the remote board, if I wiggle it or move the wires the screen will flicker brighter/darker and color will flicker bleeding / not bleeding. The connection feels loose where the cable plugs into the game board from the monitor

if you have weak connections, you need to get that fixed first.

if you think you have cold solder, re-flow all the suspected joints.

sounds like a combination of both.

you should get the tube checked.
it may need a rejuve.

if your colors smear, that can be from a weak tube.

Oh my God, finally...

I finally got a dental pick and removed all the pins from the connector and rebent/cleaned them, it looks way better. I'll properly adjust the colors tomorrow, it's a bit late now.

Looking better but even with the drives all the way down there's still a little green and red bleeding. I'll fool with the brightness/contrast on the remote board tonight.
