/vr/ - Retro Games

Alright guys I got the based grandaddy of all consumer CRT's upstairs and set up in my room, yes, the sony KV-FV310, 32 inches and 170lbs of display for the most discerning of prosumer retro gamers. Been doing some gaming the last couple nights and... I mean, I'm glad this thing was free at least. Lol. Pic related.

Does anyone with a good eye for this stuff have an idea of how much of what's going on is fixable via the service menu? I understand it'll never be like, perfect, and some games are more noticable than others when it comes to geometry errors, but this is fairly busted.

I'll consider it a win if I can at least get it to not overscan without breaking something else in the process. It has a wavy section that's noticable in horizontal scrollers, and the convergence is pretty btfo in the top right corner, but as I understand these things are either not fixable or may require opening up the case to try out stuff that may or may not work. Any tips greatly appreciated.
