I work in a Machine shop and we have a very old CNC mill from 1983 with a Fanuc 3M control. It has a CRT display that has some messed up geometry and picture. I’ve worked with CRTs of this type and tried adjusting all the pots inside to see if the image would correct. It didn’t. Any ideas on what’s causing the skewed geometry and brightness problem on one side? See image below. Input voltage seems to be correct.
