I have had my new OLED tv changed twice as it was switching off randomly. LG have also visited, so has a radio frequency specialist. App.The problem has been isolated to the sky box. It doesnt happen when the tv is on and using its built in apps or when watching Netflix via LG's but only when i watch tv or netflix via sky. When the heating or HW kicks in or manually swithching the room stat on and off will kill the sky box for a second or two it then starts up on the TV show (it is a black screen for a second or two), Netflix and other apps via sky need a reboot. It happens randomly but every day. It can happen up to 6-7 times during a show. It is not exclusive to the room stat it will happen even when the heating and HW are not on.The box is well vented. Has anyone else had this issue and know a fix? i presumed it was the TV as the Sky Q and the room stat have been in the same room for years. The room stat was also change to rule it out and the electrical have been checked for faults. All connections to the TV also seem fine.
