It has happened to us all.

I suspect the reason for the horizontal shift in the picture is due to the need to stop reading from the time redistribution memory for one line during the frame blanking period.
I cant think of the reason right now but the line chosen is critical or horizontal shift or other problems will occur.
Changing the line for 567 will most lightly cure that problem.
