After lurking on the A3000 owners' thread and setting thread for a month now, I am hopeful someone can help.
Set the TV up a week ago and have had no problems...last night, we watched We Are Marshall on HBOHD (we have a Comcast HDVR cable box w/HDMI connection). The black horizontal bars were present but at the very bottom of the top bar, a very thin line of light was also present....I checked other HD channels and it was present on all of them except ShowtimeHD which had the bars but no line of light - it kind of moves horizontally but it pretty much extends the entire way across the screen (again, this is at the bottom of the top bar where it meets the picture).
What's really confusing me is that the horizontal bars have not been present over the past week and my screen has been set to Full mode all along- I watched a football game on ESPN2 -no bars- an Alaska documentary on NGeographicHD - no bars. Of course they're normal for most movies but the bars were on every HD channel last night. And one of the programs on an SD channel was in a box with bars all around.
I tried changing the screen settings and Zoom got rid of the bars and line of light but that was just a temporary fix since it crops off some of the picture...any advice? Many thanks.
