Just bought a new Samsung and I am running my picture from my Digital Cable box to the tv through HDMI. The video and audio work great. The issue is that I have a '2' in a small light black box in the upper right hand corner of the screen. It doesnt go away even when I turn my cable box off. It does not appear though on any other input source of the tv. Just the HDMI source. My thinking is its not in the cable box, but either the tv or the HDMI cord. Any suggestions.
