I have had my projector for two years and lately I have noticed that the picture does not seem to be as good as when I bought it even though it has a new bulb. When I watch video that has is slightly dark I seem to loose all detail in the picture. When I watch the same video side by side with my widescreen television I notice that things are happening on the video that I can not see with the projector. I don't expect the picture to be as good with a 7 foot picture but I don't want to watch pivotal scenes of a film as a shadow. The white also does not look no where near as clean. I might be imagining this but I'm sure the picture used to be of a higher quality. Can I please have some opinions from people as to whether the picture should be like this and if not is it possible to improve it. If I decide to upgrade what should I upgrade to? How much better is the Sony 12HT than the 10HT? All opinion and advice would be greatly appretiated.
