Hello friends, I have a full HD 55 inch television 2016 model K6300 which is 2 years old. This is an edge lit led model. I have noticed white spots on the left most edge of the screen only while displaying bright content that is pictures or videos.. I do not see that issue while displaying dark content. I have noticed this issue only 2 days back so I cannot tell you guys accurately whetjer the issue has been spreading..What may be the issue?? Should I take this to service centre??
