512k Analog Board Distorted CRT

I've got an extra 512k analog board that I've been saving for a repair and I finally got to it today. I recapped it and reflowed all the connections, but I still get the same extremely distorted and flipped upside down video on the CRT. Check out the photo to see the stretched and upside-down video I get.

I know the analog board is definitely the problem as this machine works perfectly with a different board.

Dead Mac Scrolls suggets a few different components might be the culprit, but I didn't see anything specific to this issue. Especially the flipped upside-down part.
