Welp I have good news, but don’t have that warm fuzzy feeling of closure. I started probing around With my scope probe on the board outputs and then in the location that is pictured and pointed to with the chopstick. Low and behold in the last location the picture started jumping around and snapped up to almost a full screen. Now I was able to adjust the array of vertical controls to gets a nice full screen linear image. Quite possibly with how that inductor was positioned, it could have been shorted this whole time. I probed around with a chopstick and everything seems stable, it is not reverting back to its previous behavior. A picture of the waveform at that location while it was still having the issue as described previously is attached as well.

I am happy with the progress, this unit was shelves for 10 years and always on the back of my mind.
