Ok guys, finally all set! Replacing the BF871S transistors fixed the green screen, but when I hooked it back up I had a bunch of other issues.
Ended up doing a cap kit which came with some under-voltage capacitors. Didn't know wtf I was doing so I replaced them anyways and turned the system on which caused a vertical sync/jailbar issue, and my dark left/bright right side of the screen issue persisted.
Just got done replacing all of the under-voltage caps with some I got on mouser along with new small color transistors, a new LM1203N, and IC104. Everything is way better. Still have some minor stuff going on, I can't fix that uneven brightness issue. Nothing I've done has fixed it, but my bias tells me it's less severe now. Could be that all the rest of the colors are back and make it less noticeable.
Overall the monitor feels way more solid. Colors balanced out real well this time using the pots, which wasn't the case before. Really owe you guys a ton of thanks. This was really helpful. In the coming weeks I'm going to check some resistors that looked cracked, the snap in capacitor on the PSU side, degauss to get rid of some uneven color spots, and maybe do the flyback/HOT just because.
I also have this issue where there's gray bars that go across the screen, not sure how to describe them any other way. It's especially visible on the white NAOMI and CAPCOM screens but they are there on every screen. Thought the cap kit would fix but it didn't. Anyone have a similar issue and know a fix?
Here's a link that shows what I mean:
