Few weeks ago I had a problem with my TCL/Roku 55S405.  I resetted it and found antenna channels no longer detected; just saw the antenna icon when selecting Live TV (re-scan channels does nothing).  I swapped tuner board and TV was fine, but picture quality lessened to my eye and unit now identified as a 65S405.  Tonight I upgraded firmware, and once again lost antenna.
