RCA CTC-120D screen pinching

[Firble Man]

I’m so excited to finally be on here!
I have a couple 1948 Admirals I look forward to restoring, but I’m currently working on a 1986 RCA ColorTrak 610520611. I believe the chassis number is CTC-120D.
This TV has a pretty strong picture, especially for not being re-capped. But there is a weird consistent issue where the screen is pinched in the middle. It doesn’t stay in one spot vertically. It moves up or down depending on the source signal.

Could it be related to the pincushion board? And does anyone know what the ratings are on those caps?
I don’t know if it’s the PWPIN(pincushion) board though…The pinch moves down when playing NES, but it moves up when playing a videotape.
With no signal, it moves at such a speed, the static screen looks complete, but you can catch the pinch moving very fast with your eyes.
This leads me to believe it might be related to the signal interpreter circuit.

This isn’t a nice enough TV to bother re-capping entirely, and I kinda need to get it going for the Christmas season.
Does anybody have a theory as to which capacitor or couple caps need to be replaced to restore the screen?

Thanks for the help!!
