I have big white round spots/circles appearing on tv screen. Started with one and now have four. Samsung does not want to acknowledge this. They have acknowledged it on 2008 manufacture models but mine is 2014 and they don’t want to repair it under out of warranty product. Even though it’s a manufacture defect and Samsung is well aware of this problem. This is not right. I have everything in my house SamSung. If this issue does not get fixed by Samsung. I will stop buying this product in future and stick to Sony. I have escalated problem to escalation manager and now waiting for a call back from them.
