One thing I noticed compared to my other Sony is quite a bit of black crush. I tried tweaking the normal contrast & brightness settings first, not a lot of success. Contrast does not affect it at all. Brightness fixes it if I turn it up to 75-85%, but anything more than say 55% raises the black level way to much. Basically a completely black screen will look grey on brightness 65%. In general the contrast and brightness controls seem to behave very differently on this set compared to other Sony's I've seen. I never tweaked any of the color / picture related settings in the service menu, maybe there's something I could do there? Like some kind of gamma boost vs just brightness might help bring out darker shades without making blacks grey?

Thanks for any advice!
