Out of curiosity, isn't local dimming supposed to improve contrast tremendously? Why is it then that when I have it on (any setting that isn't off), it automatically crushes both highlights and shadows? It happens in movie mode, game mode, sdr and hdr10, 60hz to 120hz, both connected to the pc, in the google tv home menu, on youtube app videos and netflix series.

Basically, it happens anywhere and everywhere. The behavior is always the same. The model is a 65" C755 (QM8B).

Here are some pics for reference. For obvious reasons a phone's camera saving a picture as a jpeg will never be able to capture the lighting issues correctly here, but I did my best to adjust the ISO so that the issue could be seen.

This is with local dimming set to High:

And this is with Local Dimming set to Off:

At first glance the idea appears to be, from the jpeg quality, that local dimming off simply looks brighter. That's not the case at all. On the contrary actually. Even though there's bloom around the icons when dimming is off, the overall picture is brighter when dimming is turned on, and it also looks overexposed and contrast goes out the window.

You can tell by just looking at how the gears are more contrasted from the white background in the icon on the left, and also the difference in the orange tones in the elden ring icon on the right when local dimming is off. It's night and day.

This was happening in v097 (or was it v092? Can't recall) firmware. And it's now still here even with the most recent update (v135).

If others share a similar issue, please let me know, because I need to understand if I should replace my panel or just straight up get a refund and buy another TV.

Thanks in advance.

Hello! This information is contained in Build.prop file. By default, this cannot be changed! You need root right. However, there will be no update after the change this file!! The system has not allowed modificen since after Android 6. There is always a consequence of the change of file.
[Philips, Sony, TCL Android TV] ath156:
I had an exactly same experience. Due to a faulty tuner, the service changed the mainboard. I have a 65C805 (which was 65C755 in information), but after they changed the motherboard it was mentioned as 55C755 and PID 38 !!! I changed the PID to 36 (thanks to @stasiof ). I called the service and they changed the 55C755 to 65C805 !!!!! (not to 65C755).;) Also I have a "BLANK" description at the serial number....it remained as such even after updating from version 098 to 135.

Hello,

i already updated a few times via USB. I wanted to do that again yesterday, but there is no action after i press the Update button. You see it reacts, but after clicking nothing happens. Not only at USB but every update option in the menu. Anyone had this before and got a solution?

Thanks.

Hi all,

On 55C805 using movie mode for SDR, HDR, and Dolby Vision movies with different picture settings,

but the TV doesn't remember the settings when All source is set. V135.

Any solution?
[Philips, Sony, TCL Android TV] stasiof:
Instead "All sources", set "Current input" for every mode (SDR, HDR, DV,...)
[Philips, Sony, TCL Android TV] Dodge_Stealth:
Yes, I found this solutions. Works fine, but you have to set everything "individually". Thanks!

Thanks! Works now!
[Philips, Sony, TCL Android TV] SFAZ38:
Did you done factory reset after update?
[Philips, Sony, TCL Android TV] ribx:
Yes. Nothing ever solved the issue and I wasn't going to wait for an update. I ended up returning it and purchasing an X90L.
[Philips, Sony, TCL Android TV] SFAZ38:
Its unfortunate that you couldn't fix it. But in a bright side you got a good tv. Happy for you mate.

Hi,

In case of C805 what are the differences between PID ID's: 36, 37, 38?

There are Netflix and other issues with C805 PID 36, 37, and there aren't any issue with

[Philips, Sony, TCL Android TV] stasiof:
You can try test 31 or test 32 first.

Going back to normal version, need to flash IMG file first.

[Philips, Sony, TCL Android TV] likasz:
thank you for the link, which one from all the img seems to be the best?
[Philips, Sony, TCL Android TV] mNiosu:
Thank you. Version 31 and 32 doesn't solve the issue.

Tried V592 IMG update with holding the power button method but I get Error message.

Should I unzip the IMG first? Or Should I enter recovery mode for flashing an IMG?

I should note my C745 TV only has one power button on the bottom, no volume keys, so I'm not sure if recovery mode is accessible and how.

LE: unzipped, now updating. Thank you and sorry for the useless post.
[Philips, Sony, TCL Android TV] kurtschmeichel:
I checked the documents on the TCL website, they only mention the 55C745X1.

You can also find it on the EPREL (European Product Registry for Energy Labelling) website:

EPREL Public website

eprel.ec.europa.eu

Mine is the 55C745X2 revision, also on the EPREL website:

EPREL Public website

eprel.ec.europa.eu

Interesting fact, the Product availabilty section for the X2 says: "Model placed on the market from 27/08/2023." I bought the TV on 19/08/2023…
[Philips, Sony, TCL Android TV] kwee69:
Hi,

I'm picked up from Boulanger too (a model c845). And it's also a 65c845X2 made in Poland

[Philips, Sony, TCL Android TV] kwee69:
Aida 64 result
[Philips, Sony, TCL Android TV] stasiof:
You have same SoC and firmware as kurtschmeichel .

Is not V562 and "old" platform ....

So, X2 revision it's mean new platform......MT9653 and Pentonic 700.

There is no that specification on TCL EU web page yet.

X1 probably "old" platform.

X1 revision.....

X2 revision.....
[Philips, Sony, TCL Android TV] kwee69:
The question that come to my mind, it's better or worse than the "old"platform ?
[Philips, Sony, TCL Android TV] stasiof:
Should be definitely better.
[Philips, Sony, TCL Android TV] kwee69:
Thanks for the feedback. That's maybe why i don't have any issues like the black bars that everyone talk about 🤔
[Philips, Sony, TCL Android TV] syneoa:
Why better when X2 have less ram?
[Philips, Sony, TCL Android TV] kwee69:
Usually that mean more ram allowed to the gpu/io/etc. I don't know how aida64 handle the ram count, maybe it's the report from Android. It's about 300 MB/Mo less on the lasted platform
[Philips, Sony, TCL Android TV] stasiof:

Can you try take picture with Device Info HW , to confirm Aida64 2.5GB of RAM.

Thx in advance....

Btw,

[Philips, Sony, TCL Android TV] kurtschmeichel:

[Philips, Sony, TCL Android TV] stasiof:

[Philips, Sony, TCL Android TV] kurtschmeichel:
Not. Last Image with the ram section says "RAM - Total 2417 MiB"
[Philips, Sony, TCL Android TV] stasiof:
Hmm, I look at first pic only.....:sick:

But interesting, never display 32GB of ROM.

Is always arround 20-22 GB.
[Philips, Sony, TCL Android TV] kwee69:
It has always been like that. Back in the days, we had the i9000 Galaxy S which had 512 MB of ram. In Android, we had only 320 MB available(actually 300 MB on the first firmwares). Chainfire made a kernel that had 384 MB of ram available. Even a kernel called big mem which had over 400 MB of ram but at the expense of loosing 720p recording on the camera.

[Philips, Sony, TCL Android TV] stasiof:
Nothing wrong with resolution, this is just apps display under Android 11.

Hey guys,

Looking to get one 55C845K in the UK

I'm also seeing 55C841K on TCL's official web site and this is marketed as a "New Model"

I do not see any difference in the specs or features of the two...

Anyone have any idea what this C841K is? They also have C641K and C741K models listed so I highly doubt that those are just models for Amazon as rumours go... They would not be listed as separate models on the official web site if they were just Amazon exclusive Cx45 variants...

Any chance those might be the new Pentonic Chipset revision ones for the UK?
[Philips, Sony, TCL Android TV] Bikker23:
I have a 55C745x2 model with T653T01-LF1V018 firmware. Is it worth uploading the available T653T01-LF1F011 test firmware? If so, how to install them? I tried from a pendrive but the TV does not see the firmware.
[Philips, Sony, TCL Android TV] reg66:
Can't comment on your TV and firmware, but... Regarding the update, did you format the pen drive to fat32? Mine, and possibly all or most other TCLs need to have fat32. Also if it's test firmware, does it say that in the title of the file? You might need to delete the 'test...' part of the file title. Can't be sure tho as I don't own ur tv version
[Philips, Sony, TCL Android TV] Bikker23:
Yes, firmware in a test version without the name "test version" and a pendrive formatted to FAT 32. The file with the firmware uploaded directly to the pendrive in .zip format. A message appears that there is no update and the pendrive has been checked.
[Philips, Sony, TCL Android TV] reg66:
Oh... Looking closer at your firmware versions, aren't you already running newer firmware than the test version? Your current version is T653T01-LF1V018 I'm guessing V018 is the version, whereas your test file is T653T01-LF1F011. Are you sure it is newer than what you have now?

Let me check Telegram for your TV and see if there's others...

I think, from Telegram, there's newer firmware for your TV anyway... here's the link but not sure if it'll get removed as i'm not sure telegram links are allowed on XDA... but i'll try. PM me if you want the link, should it be removed. It shows latest firmware is V587 for your TV from Sept 22nd...

{Mod edit: Link removed. Oswald Boelcke, Senior Moderator}

EDIT, ignore this for now... it shows as correct TV but the firmware is different... i'll check

Nope, your model is C745 but it states that the latest FW for your TV is V8-T615T03-LF1V587. NOTE: T615T03 vs your current T653T01. Perhaps one firmware is Android TV and the other Google TV...

You'll have to wait for stasiof to respond, I don't want you to try an update that's not for your device.

Good luck
[Philips, Sony, TCL Android TV] Bikker23:
Yes, I have Android 12 and Google TV. Only test versions for my T653T01 are available on Telegram. Stasiof wrote in one of his posts that he has the test version F011 from August 16 installed (my V018 from July 27). That's why I'm curious about the test version and whether I can somehow restore it to the original version if necessary. Thanks for help.

[Philips, Sony, TCL Android TV] ANTHONY.KARA@RIVUSFLEETSO:
This is a damn good question, and one I could not get any answers directly from TCL support even.

Best I could get was C845 and 841K are exactly same bar the possibility of some superficial external differences to aesthetics which could not be rules out. Everything else is exactly same.

I cant get straight answer about C845 and whether this is UK name for QM8b that is in USA, as it's definitely not same TV as the US C845 as it's Google, different remote, different sound system built in, more dimming zones etc.

Meanwhile Amazon has a QM8b that's listed, but that's not same as US version as only 1300 nits, 2.0 sound system and no anti glare

Ive taken punt on C845 and will see how that goes
[Philips, Sony, TCL Android TV] stasiof:

[Philips, Sony, TCL Android TV] DarMaj:
In v590 when you select optical out for audio, it now mutes the internal speakers.

It's a pain is you want to use one or the other, you have to go into the sound settings and change them manually now. Is it the same in v578 and v999#24? Maybe something needs to be set in the service menu?
[Philips, Sony, TCL Android TV] drow20:
This happens even for ARC, So I just leave it on auto but the popup (Setup Sound) appears whenever I turn off my soundbar and want to use internal speakers or BT headset :-(
[Philips, Sony, TCL Android TV] DarMaj:
For me, ARC works well in the TV, but I cannot use it because it has another defect. Whenever you turn on the TV, the receiver automatic connected to it turns on. And I don't want that. If I turn it the functiin, no sound is transmitted.
