> "... If you unplug TV or you lost power on TV powercord you will need to do that ALWAYS ONCE AGAIN AND AGAIN (...)"

Ad this: LITTLE UPDATE and something curiosity. Today, the electricity (power) in my house has been ON and OFF few times for "a longer second" and.. hmm if I turn ON the TV, he started and I was curious if I need to do the above instruction for dolby vision workaround and.. the what the best is - dolby vision still work. Didn't try yet (because I don't need) to TURN OFF TV with remote control poweroff button long pressing and don't know the behavior what will be after that, but for now what I know is that - it works good even after power ON/ OFF/ flashing in your house. So its little good news, because it means the solution work and its comfortable even for older or non-tech people, but still we know the problem actually is. Sad, but if V501 still can't help with that. It may mean that the C735 and close platforms will be sooner forgotten rather than repaired I guess, because as we all know from V501 which build date is "build date= Sep 08 2022" so.. for now 3 months without any updates, the C735 platform is actually 1-st quarter of 2022 and as fair we all know the average life of chinese products, the updates will be still MAYBE half of year or maybe little more, but not further I guess and if they don't repair that, it will be our problem to the end. "Sad.. but true" - quoting the classic of metal bands (Metallica).
[Philips, Sony, TCL Android TV] mevisto:
Heh and actually is new - the V508. Just 1 post above I wrote the V501 at least for now is the newest and we all don't know the infos about the newer, but it actually is, so I should take back my words from my post above hehe about that and we all should "make a pray" that the TCL will still work for our platforms. Nice to hear. I will check the update system.

EDIT:

Being on V496 OTA (manually updated; because the system said there is nothing to update - maybe being on my region) updated from V477 stock [maybe updated from other version on the first bootup, but don't know which actually if it even happened] EU_PL, don't have system update to something newer than V496 now. Double checked to be sure.
[Philips, Sony, TCL Android TV] mevisto:
Did you or do you have any problems with Dolby Vision on your 50C635 or any stutter, laggy system or something? Any improvement do you feel being and using V508 or nothing change in user experience? Tbh I noticed the for example (at least on my TV with v496) using Spotify and listening the music and searching for a new song for a example the spotify is laggy, it isn't annoying me, but is laggy and the any operations takes seconds or maybe 2secs lag to see result, but not always of course and maybe I exaggerate this time of lag, but you feel it isn't smooth, I think the cpu isn't too **** for Spotify using, because he can do HDR-4K60FPS with smooth and good quality so.. I think its software or app problem, maybe, don't know.. hmm. My is 50c735 of course not 635, but I think its purely the same.
[Philips, Sony, TCL Android TV] lapist:
Try switching Apps Only mode on (under accounts settings) and limit background processes to 2-3 in Developer Options - that speeds up the reactions considerably (but I didn't test it with Spotify).

Hi all!

I didn't receive any emails from google neither from tcl for resetting the password. Can you tell me how to go to recovery / update fw. This tv have no physical buttons. I make a usb flash with 474 img, but it doesn't start from usb. I can make a video and try to post it here.
[Philips, Sony, TCL Android TV] lapist:
There should be a button on the bottom side, under TCL logo, at least it is on my 55C635. Hold it from powered off state (not just sleep) for a few seconds (while FAT32 formatted USB stick with IMG file on it is plugged in), until led starts blinking. If you have no button, you can try power button on the remote.
[Philips, Sony, TCL Android TV] nasosto:
Hello.

Are there any recommended settings for the TCL 65C635?

Thanks in advance
[Philips, Sony, TCL Android TV] HeyM8:
I have a TCL 65C835 (MediaTek MT9615).

I attempted to upgrade the firmware from v463 to v474 (OTA update via USB) which ended with an error message at the end of the flash process saying that it failed. I tried again and the same issue occurred. In both cases the TV rebooted OK and it remained on v463. I have successfully upgraded the firmware before, so I was surprised to see this fail. I then tried v473 (OTA), which also failed, but the TV never turned back on after the restart.

When plugged in, the power light on the TV does turn on, but nothing else happens. Nothing on the screen.

After reading some posts I've gone through the steps of unplugging the TV and holding down the power button for some time and then plugging in a USB with an .img file on it (formatted FAT32) and then plugging the TV back in while continuing to hold the power button. When I do this, the power light does begin to blink but nothing ends up happening even when I leave it overnight. I have attempted this with several different .img firmware versions and different USBs (tried 2.0 and 3.0 sticks) and I have tried both USB ports.

Are there any other alternatives to get this TV back in working order? Any way of getting some recovery menu up?

Thanks

On mine i have no buttons, only 1 LED, on the right end(you may not see it, because tv powercord is disconnected).
[Philips, Sony, TCL Android TV] lapist:
I have the button on the bottom side, in the center of the black panel with LED (which you have on the photo) - it is quite hidden. You can't see it from the front, it looks more like a screw, but you can press it.

By the way, what happens if you disconnect internet, e.g. by turning off the router?
[Philips, Sony, TCL Android TV] ndimov:
Hi lapist,

Thank you, finally found damn hidden button. But no matter how long I hold the button, I can't get into recovery. The led turn off for few seconds and after that turn on, never blinking. Somethimes directly starts and then you can see the video above.

if I stop the wi-fi, tv says something like that "You cannot continue until tv connects to internet" and show options menu to select another wi-fi network.
[Philips, Sony, TCL Android TV] lapist:
You need to hold the button from power off state (normally you hold power button for some seconds to turn TV off completely and then you can start holding it to turn on the flashing mode), but you can also hold the button since you insert the power cable.
[Philips, Sony, TCL Android TV] ndimov:
Hi lapist,

Thank you very much! Last night after hours of trying, when I removed all the cables from tv(few HDMI and optics), finally got into recovery. And now everything is back to normal. Now its on 470 version, do I need to go for 474 or stay?
[Philips, Sony, TCL Android TV] dfinikis:
I am on v474 in my 55c835, and the only issue I have faced, is that you will need to increase the brightness for SDR content, after the upgrade.

But I am not an expert user, so I would propose to wait for a few more comments, before you proceed with the upgrade. :)

[Philips, Sony, TCL Android TV] mevisto:
Yeah I know that trick, but to be honest don't wanna give up google assistant, because in Apps Only mode you can't talk to TV, my family housemates like that. And the next thing is the TV doesn't save my settings in Developer Options in this case, its kind of the settings are only for a one TV boot up [even if turn on/off with short power button clicking (stand-by)], but for a example animation speed scale from 1x to 0,5x works good and saves it well. Maybe background processes limit are limited automaticaly to STANDARD or maybe if we set 2-3 the Android think this is his new STANDARD - don't know and to be honest I doubt.

But yeahh in Apps Only mode the TV is little more smooth, but not very good for everyone and still it isn't as good as it should be I guess. Even settings menu isn't 100% smooth. On clean v496 I think is little smoother maybe (I think) than on V477, but will see in next updates.

If you can, test spotify and report.
[Philips, Sony, TCL Android TV] lapist:
Right, I also noticed that background processes limit reverts to Standard after restart, and it seems to be normal on Android. I have read that it possibly could be automatically set on TV start using Tasker, but I didn't try it yet, as Tasker is paid app.

I bought a TCL C735 75inch Qled TV and every time I try to play YouTube or Netflix it goes off after a few minutes. Does anyone have a solution for this problem???????
[Philips, Sony, TCL Android TV] drummer1839:
Try to update software
[Philips, Sony, TCL Android TV] Zuru Nasi:
It keeps saying it's the latest software update
[Philips, Sony, TCL Android TV] Zuru Nasi:
But the problem is still the same. It keeps going off when I use the Google apps after some few minutes
[Philips, Sony, TCL Android TV] drummer1839:
Do you try online update ? Or local? Download and put software on pendrive and update

How to OTA upgrade

Method 1. Network Update TCL Android TV

1. Connect TCL Android TV to the Internet.

2. Goto the Android TV Setting Menu and find and select the System Update section.

3. Choose "Network Update" from the menu that is presented (usually it shows "The current firmware is actual").

4. Follow the on-screen instructions to complete the update. Ensure not to turn off your TV until the installation is done.

This method will not reset all your settings and installed apps.

Method 2. Local Update TCL Android TV

1. Format a USB Flash drive using FAT32.

2. Copy the ZIP archive onto the drive (It needs to be the only file there).

3. Insert the USB drive in your TV's USB port (Android should recognise it, you can skip that message).

4. Goto the Android TV Setting Menu and find and select the System Update section.

5. Choose "Local Update" from the menu that is presented.

6. Wait and watch – it will take 5 minutes or so, then reboot, which will take 10 minutes or so.

This method will not reset all your settings and installed apps.

Method 3. Update TCL Android TV by Power Button

1. Format a USB Flash drive using FAT32.

2. Download the zip file containing the software for your TV to your computer.

3. Copy the software file to the root catalogue of the USB flash drive.

4. Unplug the power cord to your TV.

5. Insert the USB flash drive into the USB port on the back of the TV.

6. Press and hold the power button on the TV, not the remote.

7. While holding the button on the TV, plugin the power cord of the TV again.

8. When the software install message appears on the TV, release the power button.

9. Do not unplug the power cord during the software install. When the initial setup screen appears on the TV the software install is completed.

This method will not reset all your settings and installed apps.

Hi everyone; as a 55C635 european owner (firmware V496 updated manually), I noticed that even when using the TV without software update there was and still is a strong latency in audio.video sync when using a Bluetooth headset; I tried to use several BT headset or buds brands (Sony, Anker, Xiaomi), but there's still between 400-600ms of delay, even if I set Audio Delay at -50...

Do you have any similar issues? Should I try to upgrade to v501? Thanks.

Here it is my settings for service menu "Curve param"

First budget TV I have that backlight is good (bright enough)

Always remember to write it down the original values

Brightness

Backlight

Sharpness

Contrast

I also use AV709 MP4 to calibrate brightness (black level) and contrast

P.S: Don't mess up with contrast too much. Although it might still be fixed in the regular menu using AV709 mp4 file, it could produce a very bright/distorted image. If possible don't mess with contrast at all in the service menu
[Philips, Sony, TCL Android TV] mevisto:
You mean better HDR/ Dolby Vision experiences messing up with those settings? Better maximal brightness? What the difference between brightness and backlight? Afair the are only brightness settings in menu settings. What's the backlight? Its like a brightness 100% its equal to "curve_100" of backlight (or vice versa; like a pointer in programming languages) which actually mean 190 level of 255 [I suppose its 8 bit max value] and 100% of brigthness doesnt actually mean the 100% of backlight, but only 190/255 which is ca. 75% of led lightning possibilities? Hmm.. What about of life of LCD panel with settings like that. It's not a joke those settings are hidden in service menu I think :p We can only touch 100% level values for better HDR experiences, but if someone watch lot of HDR/ DV movies, it might be as I guess, burn the LCD panel or a LED controller of backlight hmm.. and what about warranty in this moment. It's a slippery slope. Imho I would not touch the sharpness and contrast settings. Only brightness and backlight for better HDR, nothin' more. How much you added to those curves in brightness and backlight?

It's curious to be honest. Maybe here is that marketing of better/ brighter panels in higher generations of TCL in the same platform, just the settings, nothin more ;)

Hi everyone, my new Google TV has the model number TCL 58p635. Any tutorials or tips on properly using its features would be helpful. What are the free movie apps that are compatible with my device? I live in the Philippines.
[Philips, Sony, TCL Android TV] cotenzom:
Setting

I don't think there is nothing "hidden" worth nothing other than brightness (black level) in the service menu. For other models I'm not sure, my model is P635 which is pretty basic. In the backlight settings you could adjust the CURVE so when you are in your regular setting (from 0 to 100) those will be affected. Regarding of how much I changed, I did tweak up brightness (which is black level) a little and reduced sharpness. Backlight 100 setting should be 255. This is the default btw but in some models it can be 178.

Since my model is pretty basic I don't watch HDR content, but I noticed a slight improvement in SDR. messing up with brightness. By bumping up slightly on brightness I can get better black levels. I always use MP4 AV709 file though after tweaking. Don't touch contrast unless you have special tools (professional calibration tools). Contrast is good out of the box

It's worth noting as a final note that in cheap entry level Samsung models the brightness setting (black level) is even lower by default and it can only be fixed in the service menu and it's a much more complicated process. LG entry level tvs in the service menu there is no way to fix or improve brightness as far as I know. I can definitely tell you that from a cheap model this TCL P635 is one of the best if not the best TV for the price.

If you have a high end (more expensive) model, don't bother messing up with these service menu settings, it won't help much I suppose. Higher end models are already more accurate and have decent brightness out of the box.

P.S: I do know that for TCL there are other models which backlight is 178 at 100 default, and yes, it might reduce its lifespan although I don't really think it would hurt bumping up from 178 to 190. However mine 100 "full" setting default is 255 anyway. I don't think it's just a marketing thing. If you bump up 178 to 255 in some model you might not get anything brighter. It's all about capacitors, resistors and PWM controllers in the motherboard which will affect its maximum backlight. There are limits in the service menu in all tvs and they are tied to the hardware. Each brand do things differently but people mostly use service menu to turn auto dimming off (disable ABL or DBC Dynamic Backlight Control)

. Better and more expensive models have higher quality PCB layout and better capacitors and better resistors. They also have better LED strip. The materials are also better to handle higher heat produced by the LED strip and heat produced by the capacitors. Auto dimming is another way of saving energy (let's say having a energy saving stamp by the government body). Theoretically auto dimming will make your TV last longer, but I don't think by much. It's not worth have auto dimming on especially in direct led/edge led panels with global dimming.

Hi, hope you are all well.

I have a 55C631 for a couple of weeks, running v501 (from factory) and I can´t enable "OK Google"... for the built-in mic.

I have several Google devices over the house and can activate them without issues, but I can't by any means do it in this TCL TV. My settings are Portugal/Portuguese, but I've selected English (US) as I did for other Google devices. I can use it pressing the button on the remote, but I wanted the hands-free. When I turn on/off the physical mic button on the TV I get the "Mic ON/OFF" message and when I search in Spotify the mic can clearly listen to me.

Yesterday I've tried to factory reset (which is a pain in the butt to reconfigure everything) and nothing changed.

I've double-checked the steps here.

Anyone able to help, please? I've getting nuts 😅

Thanks!!

Hi, I bought a TCL 55C635 (55-inch) TV a week ago, I am currently in version V8-R51MT05-LF1V496.020729

I have an HDMI 2.1 cable and a PC with an RTX 3080 graphics card.

I couldn't get the 120hz to work or activate the "Game Master" mode

What would be the steps to follow to be able to play at 120hz?
[Philips, Sony, TCL Android TV] lapist:
I have 178 on 55C635. What benefits would it bring to increase it to 255? I don't think I need any higher brightness, as I have brightness set to 40 in the menu..
[Philips, Sony, TCL Android TV] lapist:
First, this TV is able to use 120 Hz only at 1080p or 1440p resolution.

Second, sometimes it may be tricky to enable Game Master, as TV allows to enable it only for some sources. For example, it didn't allow me to enable Game Master with Xbox when I had VRR turned on, until I enabled also HDMI CEC on Xbox.

So you should set the 1080/1440p resolution, enable game master on TV, then see if 120 Hz is available. If game master can't be enabled, try to enable/disable VRR/FreeSync/GSync in PC, or try to adjust some other settings in nVidia drivers (e.g. if there is anything related to HDMI CEC). Also check settings of HDMI input in Inputs settings in the TV.
[Philips, Sony, TCL Android TV] mevisto:
The guy above said this is not actually brightness, but rather black level - whatever it means in these naming, didn't touch this yet. Normal TV watching I also have 45-55% of brightness afair, but in HDR/ DolbyVision mode movies your brightness and contrast goes up to the 100% and I guess in these moments you will see the difference, but actually didn't test yet, don't know, but this is as I understood that. Black level maybe mean of factor between levels of black and highest level of brightness on screen, but in normal menu we've got also black level setting slider.. so don't know, but I think the black level slider is software "blacking" the dark scences messing up with contrast maybe. I have to check it out, don't have time now. If someone can check it. Just try and compare the experience with other settings and if it is actually worth to messing up with service menu in those settings on C735 series, but C635 I guess it will be the same.
[Philips, Sony, TCL Android TV] cotenzom:
Since it's a higher end model I don't think it would be worth messing up with these settings however your backlight setting should be 255 or 178 anyway as well

Black level = Brightness

Backlight = how much power your LED (nits) goes up

If you think your picture is too dark and you don't want to increase your gamma, maybe bump up 5 points in each brightness curve

P. S: Most if not all TCL models are VA panels however there are a couple of IPS models in 65 inch I guess. In that case don't even bother with it. IPS panels are bad both for contrast and brightness (black level). 99.9% of 55 inch models are VA panels as far as I know, 100% of 50 inch models are VA panels and 99.9% of 43" inch models are VA panels as well. As for 65 and 75 inch I'm not sure but I found at least one 65 inch IPS model in sold in USA but it's rare. QLED models are supposed to be VA panels

Hi, I noticed in my Plex app logs that the app thinks my 75C635 is 1920x1080. So I checked Kodi and Aida64, and they also report 1920x1080. Is this expected? Is it only 4K if the source is HDMI?
[Philips, Sony, TCL Android TV] stasiof:
The Android TV GUI resolution is:

- FHD Panel: 720p

- UHD Panel: 1080p
[Philips, Sony, TCL Android TV] drlocoh:
Excuse my ignorance, but does this mean that any video played via an Android TV app (Plex, Netflix, Kodi, etc) will play at best 1080p? Or is the 1080p limitation just for rendering UI elements?

The Plex logs would indicate that the video is playing at 1080p and not 4K:

01-03 17:48:05.615 i: [DisplayBehaviour] Best mode for 3840x1596 @ 23.976000Hz selected as 1920x1080 @ 60.0000Hz (1).
[Philips, Sony, TCL Android TV] stasiof:
1080p is only the

app interface

. The video streaming is done at 4K, with 4K output. I know it is confusing, it was the same for me also. On 4K TV you have 1080p app interface and games, but the video streaming is done at 4K, also the output, what you see on the screen is displayed at 4K. This is true for all video apps like Kodi, VLC, MX Player, etc. The interface of Kodi for example is at 1080p but the video played in Kodi is rendered and displayed in 4K, as there are two layers that are combined and displayed on the tv screen. Hope this helps.

Edit:

I think, from Android 12 will display correct.
