I have Automan if that is necessary. Just a scan of the
horizontal sweep and pincushion circuits should be sufficient. Need help.
Thanks to all.

Set has severe overscan and horizontally bowed pix. Found a cracked board
and open foil pattern thru the pincushion section that apparently blew some
components.
I already replaced Q414(shorted), R415(open) and C415(shorted and vented).
Scope shows a good parabola drive to Q414. Checked: D411, 412, C411, C413,
C414
and L413. I need to look at a schematic. Any help or sm much appreciated on
this Wal*Mart special.
