Question
Has anyone here replaced the screen on a Rover 321? Mine is getting harder to read. When drawing it seems to be missing the vertical lines. Is there an adjustment for the screen (like on old TVs)? Is there something more modern that can replace it?

From contributor M:
Yes to both questions. I am assuming you have an RT480 control. If you pull the control out from the front, remove the top cover, and look straight down, you will see 4 or 6 small potentiometers. On the board you will see small writing for vert, horz, and others. Be very careful and choose wisely. I have played with many of these RT480's and sometimes turning one potentiometer makes matters worse along with not being able to get it back to where you started. Replacing your monitor with another is possible. I haven't done one in a while, but I remember an adapter plug being needed. I have customers with the monitor sitting on top of the cabinet as well as sitting in the original position if you find one with the correct fit.
