Reddish blacks
I have been posting in the NE forum regarding this issue, and with the hopes of more eyes coming across it, am posting here as well. I have noticed, for the past few months that my panel is tinted red when displaying black. It is especially worse on the lower right hand side. There is no uniformity to the pattern. If you get very close the panel you can see little red noise similar to dithering. I upgraded to the 1353 board and this had no effect on the behavior of the panel. I had Dave Abrams of 21st century calibrate my panel with the hopes it would go away, but still no change. My panel is isf calibrated. Day, night, and every other mode continue to exhibit the problem. Forced to live with this issue, I purchased a bias light from ideal lume hoping to trick my eyes into not seeing it. This has actually had a negative effect, and for whatever reason makes the issue more pronounced to my eye. While Dave was here calibrating my set he noticed the problem as well, and suggested it may be a voltage issue. The power in the house is clean. I have changed hdmi cables, power outlets, and bought an expensive surge protector. Nothing has changed. For me letterbox movies with low APL show the issue the issue and make the movie unwatchable. The voltage issue my calibrator was suggesting referred to inside the panel. He mentioned the lower right quadrant. I do not know enough about the engineering within the panel to know if this accurate theory. It is driving me crazy. I have come across the posts of people with the same issue (Google searches) when I first started to notice. They don't have any solutions or technical reasons this may be occurring, but at a minimum let me know I wasn't seeing things. Not sure I can capture it on camera. Any ideas?
