After about two weeks of subdued color shade for my pk550 and once in a while use of the color slide to probably help in aging it, with only one movie daily once I get home from work, I totally lost my patience to wait the 150 hours break-in and abandoned the process for my pk550.
With all the readings about break-in, I finally sided with those who do not believe, and adjusted now the TV the way I want it to appear, pushing the contrast to almost the maximum and the sharpness, saturation, etc. based on what my eyes want to see, garnering in the process the instant appreciation from my kids, who have been criticizing the required subdued color specs under the break-in mode because they have been wanting to see more color and brightness.
Now though i am still on cinema (user) mode, with the contrast pegged at 98, brightness 55, sharpness 46, color 53, tint r6 and color temp at w32, the PK550 is giving me the viewing pleasure that was deferred for about 2 weeks. I took this route considering opinions that as long as the TV is on full screen mode and no permanent image is maintained on the screen, this will be okay.
This is an experiment in itself, in opposite to the strict break-in rules adopted by plasma users here. Just like what Carlo is doing in his plasma break-in experiment, I will try to provide in this thread my observations on the picture quality of the TV. I do not intend to use my TV to experiment burn-in issues so i may report only facts about picture quality from time to time. Based on my calculations, i have already spent around 20 hours of subdued colors when i decided to abandon the break-in and adjusted the colors of the TV in its full glory.
