I had exactly the same issue bro, watching football and cricket when camera pans you can see spot on the screen like dirt mark or water mark. First i thought my screen is dirty i tried to clean it but then realised its inside the screen. Once i noticed it gave me nightmares, i was always looking at the spots instead of watching and enjoying tv. First i tried to ignore but i just couldn't live with it as it was ruining the whole experience. Showed it to service centre and they said panel is dirty from inside so replaced it with brand new tv. I know what you feeling bro as i went through same stuff. Talk to sony they might send someone first to see the issue at your place and if they decide to replace it then you can take the tv there. Good luck bro
