I have an old (1997) SVGA computer monitor (labled FIG S567) which gets
blurry once it's warmed up. I feel the tube is still good because when cold
the picture is reasonably sharp.

It used to get blurry AND brighten up when it was warm. However I
re-soldered the flyback transformer and adjusted the 'SCREEN' voltage. It
does not appear to brighten anymore.

I am hoping this is a fixable problem, and am having trouble determining
just where the problem lies.
