Hi I have a Hisense r6 50 inch and loving the tv so far. I’ve had it for a couple of years now so it is out of warranty. I don’t really have it connected to the internet. I mainly use the tv to game and watch blu rays. I’m not quite sure how long this has been going on. But I notice when I turn the tv and particularly a game console I notice there is a flash. It flashes twice witch means it’s a power supply issue. I really notice it when game systems are turned on. There was one instance where the tv shut off by itself and hasn’t done that since. Other than that the tv works as it should. Is this a common instance? Should I go ahead and possibly just replace the tv? I’ve had this tv for almost 3 years and shouldn’t be having these issues. Thanks for reading.
