I bought a Samsung LE-26R41BD about a month ago now and bar the minor tearing issue in 720p@60Hz with component video and HDMI I've been delighted with the TV. When I first turned the TV on for the first time, the picture was awful though, suffering from unnatural looking contrast levels with the picture looking more like it used only 256 colours instead of 16.2 million. However, afer an hour or so, the picture "cleared" up and it's been excellent ever since. However in the last few days, I've noticed some colour banding that "flickers" and the same type of high contrasting as when I first turned it on, but nowhere near as bad, especially noticeable on faces. Also colours flicker and you can sometimes see dark blue pixels in white clouds etc. Trouble is it doesn't happen all the time, it seems to come and go, but it happens whether I'm watching Sky Digital (RGB SCART), DVDs (HDMI) or playing Xbox games (component video). It was particularly bad last night while I was watching Boogeyman on DVD but then my TV has been on all day non-stop for over nine hours, the first time I've ever left it on that long since I bought it. I thought maybe it would have cleared up this morning - stupidly I was hoping it was a one off - but I noticed it again while played MotoGP 2 and Juiced on my Xbox and while watching Sky. Thinking my surround speakers were causing the interference, as they'd been on all day yesterday too, I turned them off and the picture "glitch" went but it came back after 15 minutes so it's obviously nothing to do with that. The window was open and there was a cold breeze coming through near the TV and I often have a tower fan on so could they be causing the LCD display to become sluggish - I've heard that they need to be warm to work at their best - or is my TV faulty? It's becoming a major distraction and I'm constantly looking for the "fault" to the point where I can't concentrate on the programme I'm watching or the game I'm playing. Anyone else had this problem?
