On a Sanyo or Fisher tv I had that did the same thing I found there is a
line from the flyback to the deflection IC that is used for horizonatal sync
and there was a bad solder job. With this line disconnected it did not have
the proper starting point for scanning and caused the picture to shift to
the right about one inch. When I soldered it everything was okay.
