As you can see my M4U on the left is much brighter and showing raster lines (faint) compared to the other one on the right. I'm pretty positive I need to adjust the screen pot but I cannot find it. The flyback has Focus 1 and Focus 2. I'm GUESSING its the pot RV709 on the neckboard but its not labeled. I've seen that used to adjust screen on other PVM's but that pot was labeled screen underneath the RV709, I just want to be sure.
