As discussed here, I recently purchased a Panasonic PT47WX42 RPTV. It is my first HDReady TV of any kind. However, I've noticed a phenomenon with my TV that I'm not sure what to make of. While watching ANY image, from Cable TV to my Progressive Scan DVDs connected using component cables, I get these horizontal lines in a periodic fashion from the top of the screen all the way to the bottom. When you are close to the screen, ie (a foot from it), they are very visible. They look almost like the NTSC scan lines. But they do not flicker, and they are very steady. But they are present enough than even when viewing from 7 feet away, I notice them being there (especially when you see a bright sky scene). These lines are more visible the lower the contrast. On torch mode, you don't really see them. I went back to the store with my DVD player and the same DVD I tested earlier, and their display model did exhibit this as well, although to a lesser degree. I've also tried another DVD player on my TV. Same results. Horizontal Lines are there. I know that these TVs have a lens for a screen, so they do have vertical lines, which are very visible when the TV is off. However, I am NOT talking about these vertical lines. I am talking about horizontal lines which I dont think should be there. I've made very sure that my DVD player is on progressive scan mode. What I am asking of RPTV owners is to please inspect your images closely (i.e a couple inches from the TV), and tell me if you see ANY steady horizontal lines. These horizontal lines are similar in thickness as those lines of the TV's lens. They may also look reddish in colour. And please tell me if you think my TV should be exchanged for a different one. Thanks very much. P.S. The store people insist those lines are normal.
