May be more story here but to me it looks like a panel issue. That's very expensive and should only be considered in warranty.
Hi, I just got a Sansung 4k 65" LED TV model UN65MU6100.
Last night unfortunatly I notice a clear thick line from the middle to the left of the screen. Any ideas what could this be? At first I thought it was a divisory line in the middle as if the store demo mode had burnt the screen (altough it's suppossed to be brand new) then I noticed the end of the line at the left.
