I just got my new 65" ST50, set it up, went to calibration and started an initial tweak. When I brought up my dish guide, I noticed the screen was dim and washed out. I went back into the TV settings, turned off anything that would automatically dim the panel, no change. I change channels to an HD movie and the screen looks great, start troubleshooting:
I figure I'll switch sources to my HTPC, when it pops up the entire panel is dim and washed out, the whites are literally grey colors are muddy. I shrink the browser that was up, and the screen popped back to life. What the?!? So I bring up My Computer, screen is ok... maximize the window, BAM dim and dingy again.
Sure enough, if the scene is too bright or has too much white it pops into "I now look like ****" mode, and pops back when the screen dims back down. I'm thinking to myself what would cause this? It can't be by design, why in the world would you design a TV to destroy the PQ if its "too bright" that's insane. So I thought maybe it was drawing more power than my conditioning block could provide (i have a bunch of stuff hooked up and this things draws some watts), I hook it directly into an outlet that I know is even on a separate breaker. Nope, the whole panel dims as soon as the screen is too bright.
I called Panasonic's "Viera Concierge" help line, the guy listens to me then checks to make sure its not dimming due to ambient light (sensor problem, etc) but I already had that disabled. He called his engineer who told him to tell me that "because of energy star and the power saving in the TV, its a feature designed inside the set itself when it starts to go outside of the power saving parameters. This is not a feature that you or I can change"
Is this true? Why does this kick in? Has anyone else noticed this or do I have a bad tv? Any help/advice/insight would be GREATLY appreciated.
