Sony KD-55AF8 - Changes colours when streaming Dolby Vision

[andhas]

Hi

I have a KD-55AF8 and when I stream Netflix/Disney+ shows that is in Dolby Vision the colours change.

I have tried to turn off all different settings that "enhances" the picture but it did not help.

If I stream a show from Netflix that is a 4k stream the picture is perfect.

It is similar or the same as this: https://www.youtube.com/watch?v=uo9EKvmrceI

I have rebooted the TV and I think it was OK for a little while but then it came back.

Do you have any suggestions on what I can do?

I've had the same problem on kd49xf9005 and power cycling was indeed the solution after making sure all image and video enhancements are off and I have the latest firmware.

I have this issue too. I find resetting the TV stops it for a bit but issue comes back quickly. 

Latest software, tried all forms of resetting and nothing! 

Sony really need to fix this as its bloody irritating

Still experiencing this issue. Restarting the TV fixes the issue temporarily but comes back shortly after. Haven't noticed outside the Disney+ app but could be all Dolby Vision content. Particularly bad with Star Wars but noticed recently with Taylor Swift Eras Tour.

It’s anything that uses Dolby Vision so a lot of content on Netflix also 😪

Have you tried to make sure that your TV software is updated to version 6.7220?

Also, you can check for updates to any of your apps in the Google Play Store. I've also heard that the factory reset might actually help.

[E_E-H92]

Yes. TV is always up to date.

Its known issue that Sony don’t appear to be in any hurry to fix

I believe that clearing the caches is also known to work for this issue, but you might need to do it every time you notice the issue, as it may come back again

It must be a memory thing.

I have an XF9005 and it suffers with this.

I gave up and now stream Netflix from an AppleTV.

We are in 2024 and the bug is still there on Sony A1.
I can confirm that fixing cache does fix the bug temporarily.

It's a real pain. Even when the cache has been cleared you are aware that the problem can return at any moment which spoils the enjoyment of watching a high-quality Dolby Vision film. It's staggering that Sony hasn't fixed this.
