Allan, sorry I have not gotten back to you. As often the case with intermittent problems, it has not recurred over the last two days so I have not yet been able to confirm any error messages. I'll come back when the video display issue returns.
Allan, the video on my Contour 2 TV finally failed again today and I can now confirm that no error messages were displayed. Only the time is shown on the LED display. I tried to upload a picture of the display but couldn't figure out how to do that. "Insert Image/video/file" asks for a URL but the image I want to upload is just a file on my Mac.
