If Samsung won't fix this, then you have to make a choice about the return or accept the defect.
The color on web sites using the on-screen browser is reversed--it shows in negative. For instance, on YouTube the previews are showing in the negative. We have reset the browser settings to Default and that did not correct the problem.
The printing is correct (left to right) so the web site is not mirrored--it displays as it should. Only the color is reversed to negative.
The video color is correct once playing.
We have also checked to be sure no software updates are needed to the tv; it is up to date.
