The fault symptom looks like there are dry joints around the vertical output
stage.
Take the back of the set and lightly tap the circuit board with the handle
of a screwdriver and confirm that it reacts when tapping the board.

Hi:
The vertical deflection went out on my TV a few days ago. It started
acting funny a few days prior to it going out altogether. I'd turn the
set on and the thin horizontal line would appear, then fully deflect, and
oscillate back a forth a few times, sometimes staying a line for a min or
two, then deflect to full screen, etc. Now it just stays on as a thin
horizontal like across the screen, about 1/8" thick.

Are there any things prone to failure in this set that I should look at?
OR, any common problems with this set in general? e.g. bad solder joints
around?
Thanks for any insight!
John
