I have a Samsung QE43Q60AAUXXU and till recently I have had no issues.However have noticed that ot will no longer then on my sky Q when I power on the TV from off (I isolate the TV with a smart plug but NOT the sky box) the sky is plugged into HDMI 1 .I have been through all the menus and can find nothing wrong if I leave the tv on standby and activate sky from it's remote control the TV will turn on but not the other way round. Any ideas please
