Hi I've been having an issue with my Samsung 4k Smart tv. All 3 hdmi ports have an issue with going in and out of sound and/or picture. The tv is updated with the latest update, just need some help on solving this issue. Thanks
Have you used different HDMI cables to see if those work? To better assist, can you provide your TV's model code?
This is going to require service. Can you shoot me a private message with the serial number of the TV?
