What is this black line on my fresh replacement panel
hello, Mine is a 55 inch curved LED TV. Model 55K6300. It is a full HD panel. I had a fresh replacement panel from samsung service centre and everything is fine except this thin black line. Its very small barely noticeable at 2 metre distance froom TV, but i wonder if its some kind of pixel death or something. I am attaching the images. Please help me out.
