It was actually brand new in it's box, just been sitting in storage for 17 years. I finally took it out, it worked for about an hour. It then stopped working and exhibits the behavior in the video. I did take it apart, visually everything looks brand new. I do not see any bad capacitors but I have not tested anything. I never worked on a power supply so I really do not know where to start.
I am aware of the high voltage present, I took the appropriate precautions while looking at the power board. I drained the anode and several large caps, I basically followed the service manual taking it apart.
