Purchased a new tv less than two weeks ago. Bought the Frame tv QN55LS03T and of course it comes with the One Connect box so you have only one wire showing. I followed directions and was extremely careful as I hooked it up to
my AT&T dvr and then turned it on. All seemed to load up and it was working for the next couple of hours. The next day turned it on and that was never to be again. It does not recognize HDMI 1, 2 3 or 4! It knows something is there because it says unknown. This went on for the next 4 days with Samsung, AT&T and the seller of the tv. I tried another one connect box, a roku and a laptop, sometimes it says HDMI1 unknown, othere times it says no signal, please turn on device. I am now waiting for the sellers IT people to call me so they can say the same thing....I don't get it! Anyone out there know anything else?
