Hi folks. I have a Samsung PN50A550 plasma TV, 50", 1080p, which has begun exhibiting some unpleasant picture issues. In dark areas on the picture (near-blacks and dark browns especially) I can see flickering green dots, places on the screen where a single pixel changes from its dark color to green and then reverts. In some areas there is a positive swarm of these green dots. They continue to flicker and change even on a completely static image (for example, a paused Blu-Ray or DVD). Brightly-colored areas (yellows, pinks, blues, whites) do not show these dots and stay unchanged. The TV is still under performance contract from the place I bought it, so they sent out a third-party technician to look at it. He adjusted "the voltage on one of the boards" on the TV and the dots were reduced (previously there were so many they were visible from six feet away), but have not gone away. I showed him that the dots were still flickering and changing even on a static image and he shrugged and said that was "normal" for this kind of TV. Now, I'd always thought that on a completely static image there should be NO change at all in the color of a given pixel. The fact that I am still seeing movement, changing pixels, on an image which isn't changing, seems to indicate to me that there's still some kind of problem with the display. Am I right in thinking this? Both my video sources are run directly to the TV, not passed through a receiver. The PS3 is connected via HDMI, and my PS2 (for old games, also plays DVDs in a pinch) is connected via component video. The issue is apparent on both sources (I used a scene from the Blu-Ray of Toy Story 2 on the PS3, then looked at the same scene on the DVD on the PS2). I also tried replacing the HDMI cable for the PS3 with no change. I viewed the same scene on my girlfriend's 720p LCD television. There are no pixel changes at all on that image when it is paused. I'm thinking the tech may have just wanted me out of his hair and so told me I just had to live with it. Thoughts?
