I have a Sony NSZ-GT1 connected to an Onkyo receiver, which is connected to my 47" LG CFL-backlit LCD TV. I notice that when I watch Blu-ray movies, I often see the image dim then brighten again and repeat this with an irregular pattern. My LCD TV is not LED-backlit and I don't think it does any kind of local dimming, so I'm thinking it's not the TV trying to dim the backlight for dark scenes (if it is, the TV is doing a horrible job of it). It may also happen during bright scenes too, but I only notice it during dark scenes. Has anyone else seen this behavior? If so, does anyone know the cause, and better yet, a solution?
