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

andhas — Mon, 18 Oct 2021 20:53:41 GMT

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?

Hey @andhas, what is your current software version? As it might be a software glitch, make sure that your TV is up to date from here.

I have the latest firmware installed.

Have you tried a factory data reset as well?

I have the exact same problem and have to power cycle it. Obviously some software glitch that can not be reset without a hard reset of tv (power off at wall). Sony need to acknowledge and fix this as it's embarrassing that their flag ship TVs are essentially broken for Dolby vision content.

Hey @ mapupil37, have you got the latest software version? Also, does it happen with a specific app? It'd be really helpful if you uploaded a picture.

Software is up to date yes. It mainly happens with Disney+ app (but that is probably only because they have a lot of Dolby vision content). It is like the TV is trying to automatically detect the colour grading or white balance and getting it completely wrong: changing the colours every time the scene changes. It's incredibly annoying I don't understand why there haven't been more complaints. I have reset all picture options to default settings and it still happens. But turning the tv off and on again from the wall then resuming exact same content makes it go away (which seems like a software problem).

No, I'm not trying nonsense suggestions. It's a bug. Sony need to fix it.

Hey @mapupil37,

Well, if you're sure that it's a software bug then it might be resolved with the next firmware update.

So let's hope for the best I guess.

Cheers.

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.

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.
