Green is not normal. Maybe just needs a slight G2 adjustment for good gray scale tracking?

Those jail bars are pretty ugly. Sorry I don't know the particular fix; guess I would play with grounds and lead dress.

I'm assuming a CCII has the DC Restore. Any idea what board it would be on (Chroma, Video IF, Video Processor...)?

I'm confident the G2 is set properly. When fed a good signal, the set produces a very good image, brightness, contrast and color. While the whites aren't has pure as I'd like, no combination of the three color taps will give a pure white. The best I can do is a white that's a bit bluer (cooler) than it should be.

If you look back through threads from around 2013, you'll find many pages of back and forth trying to solve the jailbars. I was told it was ringing, but when I scope the brightness circuit and see the wave of ringing, many would say it doesn't look like it or that wouldn't cause your issue. It was like that for just about all possible ringing sources, so I just gave up.

Thanks for you input!
