Hi, does anyone know why this happens? I just unoacked the tv with two people and followed the guide how to unpack. It only happens when the screen is dark. Otherwise perfect picture. This is a 85" display.
thank you in advance for reply’s

Hi. Is this a backlit LED TV?
These white areas look very evenly spaced, and is not dissimilar to an issue I fixed recently on a lowly 32" Sharp TV which had a very pronounced series of round white patches on a similar dark, blank screen. A YouTube search found that this was due to LED light-dispersion lenses which had fallen off! The TV rattled like a bag of marbles...
Ok, I'm not going to suggest that your lenses have actually fallen off, but I wonder if the quality control was a bit lacking when they were installed?
That's pure guesswork. And I guess it may be within accepted limits if it doesn't show with normal viewing?
