I'm a curious fellow, so I opened up the screen and replaced the main board in the Ultra with that of a Hi-Brightness and the Ultra now works, so it is definitely a main board issue. While making the exchange I noticed that the main board obtained from the Hi-Brightness screen had much more thermal paste between the cooling coil and itself. Suspicious that the lack of thermal paste between the two was what caused the issue, I removed the cover and found that one of the diodes (SL E6) is blown, as seen in the circled region of the photo below. Is this covered?
