I bought my 40L5200U a year ago, and I love it (even though HDTV prices, in general, "fell off a cliff" right after I bought it). A good picture, 3 HDMI inputs, one "custom" setting plus "Dynamic", "Standard" and "Movie" presets.
I am having a slight flickering problem on the AVS709 disc. I just got the Panasonic DMP-BDT-500 Blu-Ray player, and its settings are stock (contrast, chroma process, sharpness, all that).
Choose "Misc. patterns" then choose "Resolution". Two of the screens there are giving me problems. The "single black pixels" and the "vertical resolution - 1 pixel" cause flickering. Also, sometimes it looks like someone is playing the start of a 16mm film during the flickering, where someone wrote with a marker on the beginning of the film. Fleeting artifacts that remind me of someone's handwriting, but they are not.
This happens at both 60Hz (clear frame = off) and 120 Hz (clear frame = ON).
I have the "Tartan" 24 AWG HDMI cable from Blue Jeans cable, I wiggled it a bit, it did not cause or stop the flickering.
Does anyone know the name of this problem or the cause? Is this in the TV or the player? I don't think this will affect actual movies/TV, but I would like to understand what this is.
Do you have any ideas? Thanks in advance for your input.
