I bought a 47LB6300 two years ago. Worked great streaming everything possible until 3 months ago. I can only stream Hulu, it will not stream anything on netflix or amazon. I am running at 15-22mbps. I have reset the TV countless times. I even bought an amazon firestick to try and troubleshoot but the TV will not recognize it. The firestick logo just flashes and the screen goes black. I also bought a wifi booster and nothing has improved.
