I have this set in on my bench with and odd problem.  The top of the screen has 
a Zig-Zag effect starting at the top going down about 1.5" to 2", the best 
description I can come up with is that it looks like an upside down christmas 
tree.  It affects the whole top of the screen(left to right) I have checked and 
replaced most of the vertical section.  If I overscan the picture(by changing 
R14503(changed from 1.2 ohm to .82 ohm)) the pattern almost disappears(it 
follows the overscan).  I have exchange the flyback with a known good one, and 
the HOT as well.  Any help is appreciated....
