Roku Stick 4k Model 3820R is not recognized by LG 55LF6100-UA TV.
I tried with 2 of the HDMI ports. Powered the stick via TV USB port and provided wall adapter. Neither made a difference. The light blinks on the Stick (not red). I clicked the reset button on the stick. No impact. The HDMI ports work fine with other devices like Blue Ray and Apple TV box. What am I doing wrong?
