Yes Sam, it's a Sony TV. I do have, and use an isolation transformer.
When I checked a few pins on the video processor, I kept getting the
same waveform. When I connected the probe ground, the signal trace
would dissapear. I have since fugured out what I was doing wrong. I
didn't have the trigger set to auto. This also explains why I didn't
see a trace before connecting the probe (didn't post this). I
appreciate the concern and reply. Thanks again to all who replied.
