The picture on my LG OLED tv has started showing the skin tones of people in the centre of the screen, an area about 40cm in diameter, as grey and dull whereas people on either side the screen look normal. I have tried changing the HDMI cable, changing the picture settings and restarting the skyQ box but nothing has worked. The TV seems OK because when I stream directly from the internet to my TV , missing out the sky Q box, the picture is ok. Any thoughts?
