As per my first post in this thread i mentioned that I on my Sony 65" AF8 could see some color uniformity issues(vignetting) on certain brighter colors like on different shades of yellow.
However i hadn't seen it on any real content until a couple of days ago watching "Breaking Bad" when i loaded up "Season 3 Episode 1 - No Más" and during the intro mexico scene where they have applied this yellow filter in the desert i noticed it quite clearly see a red tint on the left side of the picture, especially during the first 5 seconds of the episode when the camera is panning down over clouds.
It got me thinking if this was something i could live with or if I should use my warranty with the store.
Since my set is still quite new ~280h, i tought it was time to see what "Panel Refresh" could do for both banding, and perhaps this red tint as well(see 20190719_Image1.jpg), well, at least I wouldnt get any surprises after ~1y+ as per Sony's recommendation and still be on manufacturer warranty.
And you know what, I actually believe I do see an improvement to the red tint, it definitely looks more faded than before, and at that point I was leaning towards keeping the set.
However, with that said, after i had run the Panel Refresh on Friday night everything looked ok with a slight improvement to banding as well as the red tint as mentioned above(see 20190720_Image2.jpg)... BUT!
After having a Breaking Bad marathon yesterday(Saturday) i noticed this, see "20190721_Image3.jpg" while loading YouTube app!
Ironically, i loaded YouTube just to have a check for banding on the 5% grey, as I've read you should run the set for a couple of hours before one can see the real result after Panel Refresh, hence the my Breaking Bad marathon ~6h!
I mean holy s***, i thought my set was toasted and went to bed with a bad feeling that I now definetely need to RMA my set... BUT!..
Starting my tv today(Sunday) it seems like it's all gone away over the night!
I can just assume it must have run the automatic refresh and fixed this but I will have to wait until tonight and take some new photos since its impossible to get a good view on it during daylight.
But I just wanted to share how quickly things can get awkward with this banding issue..
