Problem with my 55" Class 8 Series LED 4K UHD Smart TV, about 2 years old. The picture through all my devices (cable box and XBox) are showing up with a red tint. I went through the picture diagnosis process and the TV picture is perfect. This tells me the issue is within the HDMI setup somewhere. The cable box and the XBox are plugged into a HDMI splitter which then runs to the HDMI2 port on the TV. I unplugged both devices from the splitter and then tried plugging them directly into the TV. I tested both the HDMI1 and HDMI2 ports and the result was the same... the screen was showing a red tint on all the light colors. Could it be an issue with the HDMI hardware on the TV? I feel like it is the TV since the issue is happening regardless of which device I plug in.
