well, i must first admit that i am a total 100% hd newb, and probably have no idea what im talking about, but i'll do my best to explain the situation. I bought my txn2771hf from best buy last year around may 2004, and noticed a few problems. one was that the text on dvd or video games (ps2, gamecube, and yamaha dvd player, all hooked up through component video) looked extremely grainy, and there are fairly noticeable scanlines shooting accross moving images (especially over the color red). While it was under warranty, i had a technician replace both the feature box and the chassis. When I told him about the lines, he said it was a dead give away that my feature box was defective. But now, he has pretty much rebuilt my tv, and im still noticing the problem. However, ive now realized that the scanline problem only occurs in 480i, and not 480p. The picture looks beautiful in 480p. From reading threads on various wesites, I've learned how to access the service menu, and how to use it to fix the grainy text problem. But I still have the scanlines in 480i. Is there anyone who can tell me if there is something in the service menu I can change, or am just nuts?
