Hey gang I was wondering if any if you can help me with my stupid tv? problem I have is… It wont pick up live tv feed from antenna. I tried different antennas but nothing…. I used same antennas on different Tv and they work fine on other tv. On this tv tuning menu is greyed out, so I cant search for Tv channels…. I should note it was working fine till I decided to retune it to see if there was new channels. I restarted it to factory settings and nothing… Netflix, Amazon Prime and so on they still work fine. model is UE55MU6670 Thanks in advance for any help.
