I just baught a RCA D52W23. It was really grainy (tiling) and driving me crazy. I called Bright House (Time Warner) and the tech said (he came out) there wasn't anything he could do. He said it was because it wasn't a HD channel, but it's still grainy even on their HD channels. I've tried all the color/contrast, sharpness settings and nothing seems to help. It looks like crap and I'm ready to take it back and get my $ back. I have the blue, green, red cables hooked up through the HD cable box and s-video through the dvd. The dvd seems to look better though not by much. The grainyness is driving me crazy. I thought that the picture would be at least as sharp as my 27" in my sons room. Why is it all grainy?
