Adding my experience to this thread with the infamous 'pink tint' issue on the F5300/F5500.
My 2013 51" F5500 had a very uniform panel with only a very thin band at the bottom of the panel being more 'pink' than the rest of the screen. It was annoying on test slides etc. but almost impossible to spot
when watching movies/shows etc.
A year later, that panel developed a vertical line of dead pixels. The panel was replaced under warranty.
It was obvious from the minute I turned the TV on that the new panel had much worse uniformity than the original one:
Noticeable pink tint on the right and lower parts of the screen.
In addition, there was a horizontal banding issue (like DSE) that appeared on panning shots.
Oddly enough, the tech saw the DSE problem right away but could not spot the uniformity issue in my living room.
Back the TV went and the panel was replaced once more.
I got a call today from the tech saying that:
-the new panel also exhibits this DSE but to a much lesser degree
-uniformity is pretty much the same as the previous panel
Seeing as when a panel is replaced almost everything is replaced along with it save for the A/V connections board and power supply, I am wondering
if maybe the pink hue issues are power supply related.
Or this is simply a case of lower QC on Samsung's part, since Plasmas are pretty much dead.
I'm wondering on how to proceed. Should I pressure Samsung's service for yet another panel replacement? I'm guessing the entire batch has this issue.
