Yes, my software is up to date. Every blog i have read said the circuit board the hdmi ports are attached to needs to be replaced and it's a very common problem with Samsung TVs. If it's a common problem, why has there not been a recall for these TVs? I spent a lot of mo why on this 75 inch QLED tv and it's already malfunctioning and I have had it for less than 2 years.
This would need to be serviced. Could you send me a private message with your full model and serial number? http://bit.ly/2ihPL97
