Friggity frack, this thing is haunted.
I did NOTHING to it since the last power up, and now I have a picture.
Here's what is on the screen, bear in mind I've made no adjustments because I didn't want to run it out too long. Contrast control does nothing, brightness past halfway causes the picture to bloom and lose focus.
Resistors R127A and B are pretty damn toasty, but measuring 40.3 V across R127B.
