Need help on identifying the attached image on my Toshiba 42HP66 screen. I have a Comcast 8300 Atlantic cable box and use a Harmony 650 remote to one button watch HDTV TV. No problem in watching DVDs. The cable company blames the remote settings and Logitec says its the cable box. I can eliminate the problem by rebooting the cable box or switch my remote to watch a DVD and then watch HDTV.
Anybody in AV land witnessed an image like the one attached and what can one do to eliminate the problem Thanks in advance for any help anyone can provide me.
