I bought C8L 2 days ago. the picture looks really good. but I am having a slight issue. while playing video in youtube or netflix, if you bring up the seek bar, there are many horizontal streaks and also artifacts on the top letterboxing. but when the seek bar automatically goes, the video looks fabulous. is anyone have those problem or is it only with my tv.
