I totally feel your pain. I too have the UN82MU8000. The most Ive spent on a TV because they rave they are the BEST. I also came from Vizio which all them have no issues like this or any issues at all. I've only been using my 82" for a few months and I have the same lines that you describe on all inputs. It's very disappointing to see that this seems to be a common issue for such an expensive product. I would like to know though how did they resolve your issue, or did they?
I’m not sure why to do. I have a q7f 55” that I got a year ago and it just has this happen today. By warranty expired. I also bought a q9fn75” about a month ago and have 15 days left with Best Buy to return it. Is the out of warranty tv I have serviceable? Because this is bull if it isn’t.
I just got a week ago my new SAMSUNG 65" Class 4K (2160P) Ultra HD Smart LED TV (UN65NU7200)
And I have the same exact problem. And overlapping image in the bottom of the screen. Since I got it!!!
For everyone reporting this problem, what was the fix? did they replace the panel, the tv? did they take the tv away or fix it on the spot? This has happened to me also and i have a guy coming to look at it next week.
I have a brand new Q9F that was just installed yesterday. It was fine with a beautiful picture. Today while watching a show a horizontal line just appeared and stayed there.
Let's look into this further. Can you send a private message here: http://bit.ly/2Kq3B5F with the full model and serial numbers of the television as well as any pictures that you have of the symptom experienced?
