Recapped My Predicta Tandem, I don't know what to do
#51

So I found out the K network for retrace lines was under the chassis and I replaced it, I also replaced the one on the picture tube. Then I tried again to adjust everything and I can't get a good picture. I took a video so you guys can see. One video is a DVD playing, the other is my signal generator showing a 9x9 grid.

OZ4 I'm wondering if I have to rebuild the IF board next.
