Granted, however the OP did say he recapped the monitor and I didn't
want to doubt his statement.

its an IC, an LA7833( nte1773) . i'll change it out and see what happens. i did change out every cap, and it was exactly the same. no better, no worse.

thanks much

just got done replacing the vertical IC, la7833. no change in the image. no better, no worse.


Any schematic you can provide a link to? Someone suggested a bad yoke,
which is possible if the bottom half of the vertical deflection shorted
out. Maybe. However a schematic would help.
