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
