Samsung 75" model : ue75nu7100
Hello, after checking the cable and checking the picture settings on the TV, it seems that there is a problem with the colors. Maybe a hardware failure. I try to increase the volume above 9, it goes back to 8-9. I am attaching a picture for the picture color error on the screen. It also looks like this on the settings screen. It should be noted that the wifi does not work and the whole smart part of the TV does not work, it just hangs. I tried to connect a USB to perform a hardware upgrade, but unfortunately the TV does not respond when I connect the USB. Does anyone have any ideas?
