Hi, I just bought a B7A yesterday and had weird problems already. After being turned off for a few minutes, I turned the TV back on. The picture was being updated line by line at a snail's pace, except for the top few inches which seemed to work fine. Even the TV's menus were affected so it wasn't an input problem I tried turning the tv off an on again multiple times, finally eventually it all started working again. I also noticed that on a fully white screen, I could see white horizontal lines off off white color, but that seemed to go away after I ran the pixel refresher, so im guessing that is unrelated?
