During about the 2nd quarter the first half of the super bowl last Sunday, I suddenly started having “smears” or “ghosting” of the HD picture. It sort of had the same appearance as an out of adjustment convergence on an old CRT display. Players had pink outlines around them and other parts of the picture had other different colors around the edges. I've never before seen this phenomenon on my equipment either in HD or SD.
I tried adjusting “smooth motion” and other adjustments on my TV (Vizio VT420M with HDMI input from a cablecard equipped 3 tuner Moxi and Comcast) but nothing made any difference in the picture. I finally tried an SD input of the super bowl and the problem didn’t appear there. I also tried different HD programs on other channels and the problem didn’t appear there either. As soon as I returned to the super bowl HD broadcast, the problem still existed there however. It finally went away after about 10 minutes or so.
Since the problem didn’t appear on other HD programs, I finally decided that the problem must have been occurring either in the CBS host broadcast, the broadcast from our local CBS station (Washington, DC) or Comcast. If it were in the CBS broadcast, local station or Comcast, I would think that others would have noticed it as well however. Also, this may be a reach but it occurred about 45 minutes to an hour before the outage so I wonder if it might have been caused by power problems starting to develop at the stadium (ultimately leading up to the blackout later on) and which affected the CBS broadcast equipment. That’s probably not too likely however.
I just wanted to see if anyone else experienced this problem so that I can determine whether it was wide-spread or limited to my own equipment. If it was in my own equipment, any ideas on what might have been causing it? Thanks.
