But it got worse quickly. The screen goes to a pinprick and the beam intensity is jacked up. It seems like the beam intensity might be something in the z axis since the overlay text is fine.

I suspect the pinprick is from a wax cap in the high voltage section.

That was like 2 years ago. Havent touched it since. I'm intimidated by it and dont have any free time anyway
