Hello, I have a samsung 75 ue75nu7100 type television, recently it does not give the option to enter the source toolbar, not to see HDMI, not to connect to wifi, not to see a browser. I go into the settings, it gets stuck when I try to reset / update a feature / settings of the network. I tried to do a frameware update, I said maybe it will solve the problem via USB, but it doesn't upload the update either. Any more ideas? I tried to connect it to LAN but also without such success. I would love to hear ideas for resetting technicians or something advanced. Thanks
