I'm new to this forum and TV is less than a month old. I have the 5080 Pioneer Kuro. I just switched to a HDMI connection. The horizontal flashy white line at the top of my screen is there (only some times) on high def channels...and seems to happen more during commercials...anyways..it was there when I had it connected via component as well as the HDMI. I called Pioneer and they said it was my cable company and how they broadcast..blabla. I never had this issue with any other tv's. I did not use a burn in dvd and have mainly been watching HD channels and in full screen mode. Any recommendations? Thanks

It's an overscan issue. There should be a menu selection where you can correct this. Check in the plasma forum for your "offical" forum area and somebody there can tell you in no time flat.

hi
Chances are you are only seeing this with 4x3 material on a HD channel?
Your set is doing 1 to 1 pixel mapping and therefor you can see the CC information.
You can turn off 1:1 and that will hide it, however, it will cause a decrease in resolution.
