I have a 32” Panasonic TV (Model # CT-32623W) and it’s is getting some distortion towards the top of the screen. JasonRH suggested that I’m seeing the edge of the viewable area, and that I need to correct this by going into the service menu and adjusting the vertical overscan a bit to hide the edges. Can any one tell me how to access the Service Menu on my model of Panasonic and what I need to do while I’m in there? Thanks in advance, this is driving me crazy! Here are the details of what I’m seeing on the screen from an earlier post: “It is less than 1/8th of an inch wide running the length of the top of the screen. The distortion is mostly white, but it bleeds into moving bit of blue, green, red and yellow. The strange thing is, it is only visible with broadcast TV (both cable & satellite) NOT while watching DVD, and it is really only visible when the screen is black: Dark scenes, transitions between commercials, letterbox movie and shows with the “black bars”. I noticed it quite some time ago, but it is becoming increasingly annoying, especially sine more television programs are being broadcast in windscreen/ letterbox. I don’t think it has anything to do with the shielding of my center channel or L/R channels. The distortion remains when the speakers are removed and, as I said, every thing looks great when watching DVD or other sources. It’s not really like magnetic distortion (I've seen what that can look like) this is more like extra information broadcast at the top.” Thanks again!
