My Experience: Overall love the TV. Easy to set up. Easy to use. Works great as a computer monitor as well. When viewing the HDTV stations, it's awsome....especially watching sports. My only issue is with the "black" during dark scenes in shows. It sometimes gets too dark to discern the images. When I look at the same show at the same time on a standard TV, the image is fine.
Problems: Just finishing up 9 months with the TV, no functional problems encountered. Only disappointed with the TVs inability to project dark scenes well. It seems to be bothering us more lately, so it may be something that is getting worse over time.
