Wierd picture distortion on 40" Sony LCD
A month ago, I replaced our old 27" Sony CRT with a new 1080p Sony KDL40W3000 LCD. As part of the deal, the TV came with a Sony BDPS-300 Blu-ray player.
While I'm extremely impressed with the TV overall, I'm occasionally noticing some very odd glitches or artifacts in the picture.
Probably the most annoying involves certain scenes containing human faces. I'm not entirely sure how to describe it, but it's kind of like a tracer effect when the face moves. If a head turns onscreen, it's almost like part of the face (cheeks, nose, eyebrows, etc.) will lag behind just a fraction of a second. When the head stops moving, it takes a fraction of a second again for some of the face "parts" to come to rest in their proper position.
I was thinking maybe it's motion blur, but isn't that just an issue with fast moving sports, like soccer balls or hockey pucks? Faces don't really move that fast. Or do they?
Second, in some scenes, objects seem to jump around or shake ever so slightly. Strange thing is, it's not the entire picture that's shaking - just certain objects in the picture.
For example, a person in the right half of the screen might be rock solid, yet a house on the left of the screen may be shaking up and down ever so slightly. Even stranger, another object in the background might be shaking left and right. I've also seen vertical lines on an object that is supposed to be stationary become distorted and move around in a wave-like motion.
Some final points:
Blu-ray (either 1080/60p or 1080/24p) is probably the worst for this, but I've also noticed the face distortion on 480i SD cable TV, as well as on 480p from a different Sony DVD player.
This is all very subtle. My wife doesn't notice anything odd unless I specifically point it out to her. Sometimes I have to replay a scene once or twice before she’ll see it.
I can’t believe this is normal, but it also doesn’t seem like the TV is defective: the picture is absolutely perfect about 97% of the time. It almost seems like an intermittent glitch caused by poorly interfacing components, but everything is Sony, brand new, and connected with HDMI cables, so that shouldn’t be a problem. I’m beginning to wonder if these are artifacts that are present in the source, but that I never noticed before on my smaller, less revealing TV.
Has anyone else experienced anything like this?
