since updating to the latest firmware in August I have had severel problems. I have a SKY Q box connected to a new K-65XR80 which was fine then after updating every time I change channels I keep getting connected to HDMI port and when playing back recordings I sometimes get sync sound/picture problems and also internet dropping out several times a day. due to having these and other intermittent faults the sky box has been changed twice but intermittent problems still occurring any thoughts. The only thing I can think of is HDMI port problems
