Hi there thank you for commenting.so I have tried the factory reset as its the first thing anyone would say. I done the picture test but because the picture is bright and colourful you don't see any small squares you see them more when the tv has a dark or black background. However I was on sky ppv last night watching the boxing and this is when I noticed like what I would say black and Grey squares kinda like cammo effect film over the top of the picture. Now I don't know if it was sky due to the rights to the boxing. But tried watching in ultra hd and the squares became bigger so switched back to just hd hope that all makes sense thanks in advance.
