So, my parent bought a tv like 4 months back and now it suffers from letterbox burn ins, top and bottom. They did send it away to see if the warranty would help but no, it didn't. So now they are stuck with it. Is there anyway to reverse this problem? I have googled but i don't find much about this problem. I even talked to Samsung and they said that we should play the rolling bar function for at least 1 hour a day for at leat 15 days and the problem would go away.
So my question is, is this the only way? Is there another way? Can it be fixed?
