I just bought this lg smart tv um7300pua series and i'm unable to get it to connect to my uverse cable box. I go through device connector and get to the screen where is says it must be 3 feet or closer and everything. I press next and get "A temporary issue has occurred. Please try again later." I've tried connecting it to HDMI 1 and HDMI 2 (arc) and still does not work. I am hard wired to my internet also and have no trouble with that. The tv came with the "magic remote".
