Sony PVM-1354Q monitor focus

Hi all, I have a Sony PVM-1354Q video monitor that has gone out of focus. There is no external focus control. There is a pot on the board that attaches to the socket for the CRT that is labeled "focus", but it appears to have minimal effect.

Any ideas as to what I should check? I am an electrical engineer, so I can do this without killing myself, but don't claim to be a video tech. We have another one we are using, but I hate to scrap this unit if it is salvagable.

Any advice?

Thanks for any ideas, AL

Is there a pot on the flyback? That's where the focus control is normally located. If not, then either the focus voltage is wrong, or the CRT is bad. Andy Cuffe

The focus pot is on the crt socket board. Chuck
