We have one of these pattern generators (see link below) that has suddenly
shifted the video from the composite output to the right about 10% of the
screen size. The failure occurred rather suddenly and not over a period of
time. I figure a timing problem, but there is no service info available
from the manufacturer, nor was I able to locate any info using Google. The
manufacturer did not even deign to respond to my inquiry. Can anyone help,
or possibly supply me with a schematic?
