Hi Ethan, Yes, it was quite enjoyable bringing this machine back to life. Admittedly Ray Carlsen did most of the hard work. FIxing the monitor was very rewarding indeed. I've never worked on a monitor before. Considering the scary high voltages involved and my lack of knowledge fixing analog circuits, I was skeptical that I'd get it working.
