Unit works for 1 hour then stops with the message "weak signal". Internet identified a 'grace period' of 1 hour if HDMI cable or TV problem identified. Purchased new HDMI cable... same problem, same 'grace period' of 1 hour. The HISENSE Smart TV hasn't been able to get some streaming services, hense the google TV streamer, but otherwise is a good TV. I have solid internet connections and WIFI. If this unit can give 1 hour of service twice before failing, surely it can connect for longer
