thats good will give reset to intial settings a try, hope its some software issue & not hardware, well got warranty but who wants the hassle. The issue starts with my d2h 4k stb & then when the patchy colors are on screen it comes everywhere even on the inbuilt apps like amazon, A reset in the picture mode brings colors back to normal, i m using an old hdmi (high speed) cable between stb & tv, will change that with another cable & also will try a factory reset to see if the issue goes, otherwise will have to call Lg, hope they replace my unit with the new 55C7 thats out now on their site
hyeah:
