I just got my new KV-36FV27 and like it very much. However, I find that on some movies, the picture is very dim, and I have to crank up the brightness level in order see any detail in dark or shadowy scenes. I calibrated the set using the THX Opti-Mode on my Toy Story 2 DVD, and while it works fine with that movie, other movies are far too dark and dim (such as "Witness" and "Good Will Hunting", both anamorphic versions). I find that I have to increase the brightness level to maximum (+15) on the Panasonic DVD-RV31 in order to see details in shadowy areas. (My DVD player has built-in brightness control, so I am not actually using the brightness control on the TV.) Other movies, such as "Tootsie" and "Ben-Hur", only require a +7 increase in brightness. The movie "Superman", however, requires no increase in brightness at all. These movies were all viewed with all the lights turned off at night. I never had to do that with my 9-inch Sony and so I am wondering if there is something wrong with my new Sony 36 incher. Don't get me wrong--once the brightness is cranked up, the picture is awesome, but I am wondering if I am shortening the life of the tube if I have to do this for every second movie I watch. I'm also afraid that the set will get dimmer as it ages, as all TVs do, and by then even cranking the brightness to maximum won't help. I plan to keep this set for at least five years or more. I noticed in the store that the 32 inch WEGAs were consistently brighter than the 36 inch WEGAs, even with the same settings. Are 36-inch and bigger direct-view tubes inherently dimmer than smaller ones? Or would I have to upgrade to the 36XBR450 to get a brighter tube? I don't really want to get a rear-projection set, as I prefer the wider viewing area of a direct-view set. And I don't really want anything smaller than 36 inches because a lot of the movies I watch are letterboxed-anamorphic widescreen. (I also watch a lot of 4:3 movies and TV shows on DVD, so I still prefer a 4:3 set.) Right now, I use mostly the "Vivid", "Standard" and "Sport" picture modes. The "Movie" mode is far too dim to be useful. I have turned off Velocity Modulation and also decreased the sharpness in all modes. Is this dimness something I can fix by going into the service mode? I really do not want to do this if I can avoid it. Any help or comments would be appreciated.
