Have this Sony set, it has a single red, green, and blue line at the top of the screen. There are only 3 lines. Almost looks like vertical retrace. The vertical circuit seems to be operating correctly. The set has a full picture and the picture looks great other than the 3 lines at the top. I want to say it is the WY board (A-1415-602-A). Any other suggestions or has anyone encountered this problem?

Thanks in advance.............

I'd still check all electrolytics in the vertical output circuit and power sources that feed it. If you have another output IC, try it.
