I have a 21" Dell CRT monitor. About a third of the way from the top of the screen there is a horizontal line - just like you see when an entire line of pixels fails on an LCD monitor. It's only very faint at the moment. The line is dead still (doesn't roll with the refresh rate) and it is (obviously) more noticeable when the screen is white or the white mouse pointer is positioned so the line passes through it.
What would cause this kind of fault !?
Allan.
