Hi!
I have new 65XF7596 for 5 days and together with it an bug from the Colour Settings:
When setting the colours to an acceptable level (e.g. to 55) and then returning back to watch TV (e.g. channel 001) on Digital tuner programm (Cable TV), upon changing the TV channel (e.g. on 032), the colour saturation will be to a level 15-20% above the level that has just been set (even though colour setting is still showing as 55), on all TV channels (001, 032, and other).
Android 7.0 (Nougat); latest firmware - 6.5629; demo mode (retail) - off; Reset to factory settings - done; Auto Picture mode - off
Is anybody experiencing this problem? Or knows how to fix?
Hi @roma.avp,
You make interesting remarks. I suppose your remarks relate to the digital tuner programmes. I believe you should be able (this might be locked, depends on different factors) to tune manually two subsequent channels to the same programme frequency on your TV. Then retry your test. So as an example you tune ITV1 both to channel 001 and 002 manually then zap between them to look for the bug you mention.
Generally speaking these kind of tests would require an SMPTE test signal generator and a professional colourimeter to measure the offset. Yes, all programmes from different broadcasters comply with the same REC.709 colour space standard for SDR signals, but every single programme (shows, movies, documentaries, news, etc.) and I even dare to go as far as saying every single scene from the same programme (in more advanced formats even frames of the same scene) are colour corrected differently by the colourist during the post production. This makes it impossible to measure differences if you are zapping from one channel to the other, as the whole colour processing scheme behind both channels is never the same. This despite the colour processing done according to your settings on the TV remains the same during the zapping.
Cheers,

Hi @dutchice
The settings on the TV do not allow to manually tune one cable program to two different channels. Therefore, I can not repeat the test on the proposed method
Please see the corrected description of the problem.
Hi roma.avp,
Welcome to our community!
I'd like to start by agreeing with Dutchice that colours could differ greatly from one channel to the other even with the same picture settings on your TV.
I'm also intrigued by the fact that you mentioned that the colour saturation increases by 15-20% which is a pretty accurate figure. Could you let us know how did you manage to measure this increase?

Hi @batee5
For example, on channel 001 I adjust the level 55. After switching to channel 002, all colors look as if the level is set at 80-85, on all channels. That's how I measure this increase with my eyes.
Then, if you change the level to at least 1 (+ or -) on any channel, the colors becomes normal, which corresponds to the set level 55.
It's not about how accurate the percentages I wrote, but that this obvious bug is there. And this bug is not only for me. See:

I have been watching TVs from vendor Sony and other vendors for many years, and I'm not blind, and I do not need special devices to see the obvious bug. And from the channel number it does not depend, and from the TV provider does not depend. There is a big bug and I described it as I could (sorry for my English).
Hi roma.avp,
I'd suggest ringing Sony to bring this to their attention so that they'd look into it as I haven't came across it before.
