Hello.
I’m Sai NiYom from Myanmar.
We don’t have such things as professional TV calibration here.
We have to make our TVs’ color look as good as possible on our own.
My recent TV is TCL P8M Android 4K TV which I bought one and half year ago.
I was very satisfied with it until I messed up with white balance 2 point values while playing an animation film in HDR.
I reset white balance, did factory reset, upgraded the firmware and did everything I could to get the colors back to normal.
But the colors are not the same as they used to before.
I’ve been struggling with it for almost a month now and I would like to ask for your kind suggestions.
Thank you so much in advance.
Try again factory reset and afier flash IMG file...maybe help.
Edit:
You didn't play with "Service menu"?

my 55P8s uses the GMT+0 (UK time) since updating from stock firmware, and this resets to that time zone every time I turn off then turn on the TV. any solution for my time zone to persist (GMT+8/UTC+8)?

Hey team,

I am trying to flash this on my 50C715, the update is not recognised by the TV.

I have tried the full zip and also extracted it and neither will be detected.

In root of USB, its it the ziip or the extracted folder? Does the name of the folder or zip for this one need to be renamed maybe? The name of the download is V8-R851T02-LF1V649.019097.zip


thanks

I would also like to share a tool to debloat TCL that I have scavenged from 4PDA. If anyone knows Russian alphabet, could you write a working tutorial for it?

I have not actually used R709. I've gone through v389 which was atrocious, v645 which improved a lot of colour bleeding/blurring, and now v649 which I have to say, is another improvment and is at the moment, awesome. I never had the HLG issue, or could not identify it if I did.

Since update to v649, I've used the PC and streamed 4k HDR Netflix (Defenders and Lost in Space). The colours are more natural but very colourful without being over the top, no bleeding at all, and us noticeable sharper, clear and more defined. Specular highlight very sharp and detailed.

It could be all imagined, but it does seem clearer.

I wanted to return the tv after a week, quite happy with it now

What picture settings are you using? And do you use the dedicated PC mode?
