I have the Hitachi 43UWX10b, calibrated with Avia (on a Panny RP-56 DVD) and rechecked on a weekly basis. My settings thus far have been (with all auto color, noise reduction, etc. off): CONTRAST - 30 BRIGHTNESS - 55 COLOR - 40 TINT - +2 green SHARPNESS - 20 I went out of town, came back three days later, turned on my set and noticed that everything looked washed out. The only thing I had done was pull the TV away from the wall to reconnect my X-Box. So I recalibrated, and now my settings are: CONTRAST - 30 BRIGHTNESS - 46 COLOR - 41 TINT - +2 green SHARPNESS - 20 So is this just something that happens? It seems odd to me that my black level would change that much. It isn't just for one source, since it looked washed out on DVD, cable and X-Box. I'm just concerned that this could be a sign of a bad unit or some impending doom. Of course, I may be paranoid because this is the third 43UWX10b I've had since my original purchase. Is this just something that happens with break-in? SOMEONE PLEASE EXPLAIN IT TO ME!
