so I played around with my 46st30 may build last night. I cant notice any of the major issues, no buzzing, no blobs, no dead pixels, or smears.
I definitely notice the fbr issue though. I have only watched sd cable, but I would occasionally see the brightness shift in and out, but even weirder, and I am guessing fbr related, was that right when an image would cut to another angle it seems it would get significantly darker/brighter, right on the cut. it was especially noticeable in commercials that should have a solid white background through the whole thing(like an apple commercial) it would start bright white, then cut, and the whites where a muted grey, then cut again and be solid white, stay like that a bit, then cut to muted grey.
This happened on every channel and every show, bright highlights, then would cut to muted whites. I thought the fbr brightness shift came delayed after cuts in a video, not exactly on the cut, it looked the brightness shift were built into the content. So is this the same thing? I also connect to the network and downloaded the latest firmware. I am gonna call panny today.
