Hi, I've owned my 60638 for 2 years. Never had an issue with it. I recently moved and switched states. and now I've been having issues being satisfied with my colors.
I play Xbox 360. I used to use Brilliant for playing games, and Bright for watching movies, after much fiddling with settings found what I felt was the best picture for each respectively, and everything looked great.
I replaced the bulb about 3 months ago due to the original started to flicker faintly. No problems following the replacement. I think it is an OEM bulb as it looks identical to the one that was in there. Same markings and all.
I've moved now, and since the move, Brilliant looks like it has a lot of brown. When I go back and forth from Bright to Brilliant, I can see where Bright will show shades of green on some foliage, and Brilliant turns those shades of green into an autumn brown color. Brilliant also seems to add a faint haze to the screen, like too much brightness, even though the brightness setting seems to be correct to the THX calibration.
I don't know if it's because my old house had blue walls, and my new house has yellowish, peach colored walls...that might be the culprit, creating an optical illusion, but I'm not sure. I just don't remember Brilliant looking so brown...I remember it popping really well.
For now, I seem to be happiest with leaving the TV in bright mode, with the brightness several clicks below what THX calls a calibrated black level. If I leave the settings at the calibrated black level, then the picture looks washed out, and that's on both Bright and Brilliant.
I pulled out my laptop and pulled up some HD footage of Halo 4 on youtube, then paused on several colorful scenes, and then did a side by side with my character on my TV viewing the exact same scenes to match up the colors (since the videos were from IGN, I assume they were using high quality calibrated displays). The settings which i found matched best were:
Color Temp: High
Video Noise Off
That is from memory, the actual numbers might be a bit different, but that should be close. Anyway, I think it looks pretty good for what it is...but from looking on this forum, I haven't seen anyone with recommended settings even close to these. So I'm wondering why my TV changed so suddenly. I don't think it could be damage from the move or else I would imagine the problems would be much more severe. Perhaps a shoddy bulb? Color wheel? Maybe it's nothing and there are people that use these settings too? I don't know.
I am sorry for the long post, just trying to be thorough and hoping someone with more experience than myself can shine some light on this situation.
Thank for reading!
