I repaired a non-functioning CRT display on a 784D by changing out CPU board. Similar to your problem the VGA port display worked fine.
While researching the problem I believe one of the youtube posters said that the video chip was very static sensitive. And he blew out one by probing the pins??

Not sure if that helps.
I didn't chase the problem board any further after selling the repaired TDS784D.
