BlankGentlemen,
I'm having an elusive vertical problem with the above described which is =
producing a horizontal line 1/4 of the way down from the top of the =
screen.  No schematic on this one, but from past experience it seems my =
in voltage might be low on the vertical deflector U4501.
I've replaced U4501,  and about 8 of caps in that circuit, (C-4502, =
4108, 4107, 4506, 4505, 4705, 4112, 4404) with no change in symptoms.  =
My voltage readings on pin 1 and 2 of U4501 are 13.4 and 24.7 =
respectively, and 23.0 on 5-Vout.
I've traced circuit for open shorts with no luck, and quickly running =
out of patience.  Any help would be appreciated...
