Repairing Samsung TX-T2793H - Poor yoke maybe

[DeathByBFG]

As the title states I'm trying to repair a Samsung TX-T2793H. The grid pattern is all sorts of messed up. It's super enlarged at the top and on the bottom it's tiny. Plus it's very blurry on the edges. The latter I believe is just a flaw of the set design. I was able to fix it a little bit by adjusting the yoke. But the difference is kind of minimal. I don't have any before pics, unfortunately. Does anyone have any advice on how to resolve this? Also, it doesn't show up on camera, but I believe some vertical foldover is starting. So I'll need to find the vertical output IC and find out which lead has a cap to replace.
