Hello everyone, this is not a question about firmwares (so pardon me for the slight OT) but about a very basic use of an 50C725 (latest 267 firmware): when you connect the spdif toslink audio output, what do tv speakers do? In my case they're always on, I can adjust the volume thru the remote but it's always the tv speakers, not the spdif output. I expect that connecting the spdif would disable the tv speakers (like the headphones jack for example)! I cannot find any option to do that and I don't understand it's a defect or the normal behavior (but if it's normal it makes spdif output useless...).

In the advanced audio menu I put "digital output" on pcm; moreover the sound I'm hearing is dropped now and then, like if it looses sync. If I choose "auto" or "transferring" I get only loud noises (and tv speakers always on). The spdif cable is connected to a SMSL M500 dac, and it worked flawlessly with my previous tv set, so it's not its fault.

Please help me, I'm going mad...

[Philips, Sony, TCL Android TV] azz_kikr:
No solution. It's same here, you either mute the sound (leaves icon on screen) or you put the volume to 1 and let the soundbar sound louder. What I did tho is put the volume to 1 and plugged in some old headphones. No more sound ( not from speakers anyways)

Anyone tried that new custom firmware yet? Anything new or noticable?
[Philips, Sony, TCL Android TV] pumkin_100:
I installed the 029, but the Atmos not support the internal application. But the UHD player via HDMI is supported. It caused the NETFLIX and Disney + cannot support the Atmos sound, only the 5.1. I want to back to the last OTA version.
[Philips, Sony, TCL Android TV] pumkin_100:
How do I back the low verison? Would you please share the low version IMG to restore? Because the 029 cannot support the Atmos for the internal NETFLIX, only the HDMI, played by my UHD player. Thanks

[Philips, Sony, TCL Android TV] stasiof:
If you are already on T615T01 firmware .....yes.

If you are on T615T02 ,you will lost Google TV and

no revert back, as T02 IMG not released.
[Philips, Sony, TCL Android TV] hardlineca:
Do you have an img for 024 or some other official release for this who went to 073
[Philips, Sony, TCL Android TV] stasiof:
No IMG file (T615T02) for R646 released yet.

Btw,

on V073 (R646) you also "supose" to receive auto update (> 074 and above).

I follows TCL more then 2 years and about 20-25% (worlwide) ,never receive any auto update, even they are on factory firmware.

So, they must update manually, of course if firmware is availabe in OTA zip form.

If not, they flashing IMG normal "V' version or custom "R" version.

I am having a specific issue with my X925. When Dolby Vision content starts playing, the image changes to a washed out full brightness version of DV IQ. It is not until I go into picture settings and change Dolby Vision IQ to ‘Bright’ or ‘Dark’ then back to IQ that the image looks correct. I have to do this every time. Does anyone have any suggestions?
[Philips, Sony, TCL Android TV] stasiof:
When playing Dolby Vision, adjust setting for your need and in pic setting set ..Apply for current input.
[Philips, Sony, TCL Android TV] RichUltra:
I have done this, but it resets each time and goes back to the full brightness version until I do the swap in settings.
[Philips, Sony, TCL Android TV] ASKnASK:

Peak brightness is arround 1000,you can found in many reviews.

Black crush issue,I don't know.

Please could someone Id my TV as it was brought as a 65C729K 2021 UK from amazon 2 months ago. Been looking for android 11 firmware but the more I look into the TV settings the more confused I get . Any help greatful to confirm I do have correct model and if you could let me know what android 11 firmware I can flash.

It has firmware V8-R51MT02-LF1V130
[Philips, Sony, TCL Android TV] stasiof:
Bro, no need to post same thing every 2-3 days.

2021 TCL models for UK are all Android 9 and differ from Europe spec and firmwares.

Since a month ago, TCL stop posting (and relocated) firmwares on they known server.

At the moment no clue even for older TCL models ,specially not for K...UK models.
[Philips, Sony, TCL Android TV] Nobbymk:
Sorry I was asking because if you look at the CPU specs and platform it does not seem to be the specs for that model and in Amazon discription. Just wanted some who knows a bit about TCL if then can tell me the specs in the pics match what the Amazon discription for 65C729K 2021 match as it didn't seem to , to me.
[Philips, Sony, TCL Android TV] stasiof:
As I posted earlier, UK 2021 models are different then Europe models.

UK.... C728/9K and C825/6K ....models are with Realtek SoC RT51M and NOT with MediaTek 9615 (as Europe models).

Hi @stasiof! I just bought a 75C728 in Saudi Arabia so I guess it is the EU model with MT9615. I updated the TV to latest v083 as was posted by you and the image quality appears to be dark overall in HDR/SDR or even DolbyVision content played from an External HDD using DV Bright setting.

I also have a 50C715 model which has overall better image quality with proper highlights in DV videos compared to C728 which surprises me as I was hoping the new model would fare better.

Did you notice this behavior with your TV on v083 as I didn't test anything on its original firmware which it came in (v027)

Thanks for all your support on the TCL TV's you've been giving.
[Philips, Sony, TCL Android TV] stasiof:

My 55c725 just got updated to Google tv

My firmware version is still the v267.

I just got a notification saying there were new functions available, I clicked ok and then I got the new Google tv interface
[Philips, Sony, TCL Android TV] anhil:
In which country are you using your 55C725? I am in Finland and originally had v256 in my 43C725. Since there were no OTA updates available, I updated it locally to v267. So far no updates offering Google TV interface are available OTA in Finland.

How do find Google TV interface after having been using the vanilla UI of Android TV 11?
[Philips, Sony, TCL Android TV] Atwd:
I'm in Italy. I updated to v267 manually because I never got any Ota updates.

The new Google tv interface is amazing for me. Before I had a lot of problems, menu sometimes froze, often I had to clean the ram using the pre-installed tcl app TV protection because everything started to lag and stutter.

After I got Google tv interface, everything is fast and great, it's the perfect TV now.
[Philips, Sony, TCL Android TV] anhil:
Thanks for the valuable information!

I have understood, that Google TV is more or less a sort off add-on on top of the Android TV UI. However, it should enable the UHD resolution for the UI (if your TV is equipped UHD display and TCL is). Android TV 12 should bring this UHD to UI in the native bottom level. Can you confirm, that this Google TV update your received actually enabled UHD on the UI?
[Philips, Sony, TCL Android TV] Solarean:
Are you sure you got the Google tv experience? I got the "new functionality" message as well. But it just gave me the newer android TV experience. Not the Google TV experience.

As I said before I already had v267 before.

I didn't install any update.

I just got a notification saying there were new functionalities available, I clicked ok and the TV reboot. After that, I had the Google TV interface.

At least it looks just like Google TV. I don't know if it's an update that makes Android TV to look like Google TV, I can say that on screen it's literally like Google TV.

Hello everyone.

I bought the TCL 43C725 TV. From time to time I have areas of red contrasts (or small red spots on moving subjects). This is especially visible on shadows of people in the foreground. I tested all sources with all modes. Nothing changes...

If I flash the firmware with a newer one, is there any chance that this will correct the problem?

What firmware should I put please?

Thank you.
[Philips, Sony, TCL Android TV] anhil:
What is your current firmware version - v256 / v267 / v272 or something else?
[Philips, Sony, TCL Android TV] cedrikk:
Hi and thank you !

Product version : V8-R51MT02-LF1V272.02169

Version TV+ OS : V5.2

Have a nice day !
[Philips, Sony, TCL Android TV] anhil:
OK - you have already the latest firmware v272 there is available. It could be possible, that this latest firmware would have introduced these problems your described and actually downgrading to the previous version v267 would help.

In my 43C725 I have version v267 to which I updated locally from v256, since nothing newer is available OTA in Finland. I cannot spot these problems you mentioned in my tv.

If I recall it correctly, somebody in this thread mentioned about problems with v272 and he decided to downgrade to a previous version. Just browse the previous postings in this thread.

On the other hand, these is always a possibility for a hardware problem and to that, the only recommended option is a warranty replacement.

[Philips, Sony, TCL Android TV] anhil:
This will undoubtedly have an impact to the firmware updates of the European lineup of TCL televisions. Not only will the launch of Google TV (or Android TV 12) be postponed but also other firmware developments will be delayed since all hands are now busy repairing the damages already taken...
[Philips, Sony, TCL Android TV] Atwd:
I think it will actually push tcl to work harder on software updates. They're too slow, they need to be faster and to make updates without bugs
[Philips, Sony, TCL Android TV] anhil:
I actually got these same new features today as I restarted my TCL 43C725. Interestingly, I got the same features also to my Android TV box, MECOOL KM6 Deluxe, running Android TV version 10. So this is some kind of a face lift update distributed by Google globally for the Android TV UI regardless of the generation. I cannot say it is love at the first sight but perhaps I will grow to tolerate it...

[Philips, Sony, TCL Android TV] anhil:
In my 43c725 I have installed v267 as a local update - there is nothing available OTA in Finland. You can read about some bad experiences with v272 in earlier posting of this thread. Therefore, at least I have no intentions to update to v272.

If someone uses Google Stadia on the tcl C72, I suggest you to enable "force gpu" in the android tv developer options.

Without it, the streaming is very bad. Also it's better to use an ethernet cable. For some reasons the Wi-Fi antenna of the TV doesn't seem to be able to keep a steady 40mbps even if it is on the 5ghz network and just 2 meters far from the router.

Now it works great.
[Philips, Sony, TCL Android TV] DidierXDA:
It's stupid, he works on my Samsung TV.

It works for a Bluetooth output but it's impossible with an optical output.

I have different Satelitte STB (Edision OS MIO 4K +, Xtrend 9x00) connected to HDMI LED TV Samsumg and Bose Acoustimate in optical connection, it works great.

I regret to buy this TCL TV.

It doesn't make any sense what you're saying.

If you connect your speaker to the TV via Bluetooth or hdmi, you'll be able to control the volume with the TV remote.

If you connect your speaker via optical cable, you won't be able to control the volume with the TV remote simply because the optical interface doesn't allow to do it. It's the same for every TV, it's not a tcl problem

[Philips, Sony, TCL Android TV] anhil:
If your Bose Acoustimass system has HDMI input in addition to optical one (there are many different variations available in this Acoustimass family), the obvious choice would be to use to use HDMI connected to the HDMI ARC enabled connector of TCL and use HDMI-CEC to adjust the volume comfortably with the remote of the TV. However, if your Acoustimass system does not have any HDMI inputs, his does not apply, of course.

Hi guys any custom firmware for the c729k UK yet , on v191 after help from stasiof but still wanted to upgrade to android 11
[Philips, Sony, TCL Android TV] Atwd:
I understood very well.

What you don't understand is the optical cable doesn't have the technology to let the TV control the speaker.

TCL is not a stupid machine, the stupid is the one who doesn't understand the technology and complains instead of trying to learn.

Your Samsung probably has a function in the TV remote that connects directly to the speaker, so it can control the volume directly. It works the same with universal remotes that usually can control TV, speakers and dvr with just one remote.

But you cannot control the volume through the optical cable because it's technically impossible. Optical cables can stream only audio via a optical signal, they cannot send commands like "volume up" or down
