Had a real fright today. Went to watch Wolf Creek on my 506XDE which had been recorded during the week on the SkyHD Box, when I noticed a "dead" bright blue pixel half way across the screen, about 8" down from the top. It was so bright, it seemed to light up the adjacent cells, which made a real mess. I moved back from the normal 9 ft, to 25 ft, and could still see the blob clearly!! Now I have been carefully running-in for the last 2 months, but had turned the wick up for this film. I quickly switched to the menu screen, and could see nothing of the little blighter (then I thought it was invisible due to the blue background). Quickly tried another recorded film, which was R-Point, and guess what? Still the "dead" pixel was present! My heart sank, until I later switched to a normal Sky channel, and no blue pixel was evident. Flicked to other channels and recordings - nothing. The effect was only present on the films I have recorded from Film4. Has anyone else noticed this?
