TCL P6046 suddenly DARK - Philips, Sony, TCL Android TV

Problems with a TCL P6046..
Suddenly the brightness went to "almost black". You can see the image but it is very dark.
The strange thing is that when restarting the TV, the brightness of the TCL brand and the loading of android are very bright.
Tried:
Empty the cache and restart
Disconnect the cable, press the button for 30 "and reconnect
Install the 820 OTA version from scratch, so "implicitly" reset to factory values
Unfortunately, apart from a phenomenal new boot speed (!), the new 820 fw hasn't changed that
The strange thing is that in the first few seconds of boot, until the complete loading of android, the brightness is normal.
But the system saw all settings rewritten with the ota 820 update ..
Kindly ASK
What can it depend on?
Any Ideas on what else to try?

[Q] Desire HD - no reaction in the boot menu

Hello. Today, in normal use the phone suddenly hangs.I ran it again in the bottom left corner of the screen appeared the words EMERGENCY MODE.I decided to switch off the phone again, however, joined the boot menu where nothing can be done(i can not move or nothing to choose).After removing the battery and re-insert the phone once in a few seconds goes to the Boot menu, and repeats the situation, do not respond.The only thing that happens after a while subtitles that pop up .. pd98diag.zip file and others are wrong or missing.However, after about 1-2 seconds it disappears and the phone still does not respond to anything.
The phone was recently rooted. Custom rom was uploaded: Arky's ROM 2.3 OC-TV.
Sory for my bad English. Any ideas ?

U65X9006X1 TCL / start error- boot im

Hello everybody,
I have a problem with my Android TV.
TCL
U65X9006X1
The problem is it won't start completely.
After switching on, the TCL symbol appears normally, then a symbol with a red X, and now the animated Android TV symbol and that's it.
The Android TV animation runs on and on and on at some point after about 1-2 minutes the animation is gone and now nothing happens.
you can only see that the backlight is still on, but nothing else happens.
I can start the firmware update via USB and it apparently works, but then the same problem.
The device has only one control stick on the TV with which you can only execute one command at a time.
Do you know how to get into Android Recover?
Is there any other idea?
what can I do? Guarantee is over.
My english is not enough so i have to use google translater.
thanks
greetings from Germany

Which firmware you using on USB ?
Hello,
...v574
OTA or PKG ?
V8-T658T01-LF1Vxxx ?
what is the difference?
I downloaded the original firmware from the TCL homepage.
V8-T658T01-LF1V574
Something prevent you to boot, so need to clean your TV with fresh update, which will wipe all your programs inside.
Please refer to this thread:

At least I get your answer.
Zip file(s) wan't help ,so try reflash with .pkg file (power button).
Flashing with pkg file, will wipe all your apps ,settin, etc....
You can found pkg file in thread I posted earlier.
Hello,
why shouldn't I answer?
I somehow managed to start the RecoverMenu, reset everything there and now it starts normally again.
I'll try to reproduce it and will report.
OK,good.

TCL 65P815 firmware update problem and few things

Hi,
My problem is with 65P815. Fabric software was v084, i tried to update to V191 official version from TCL page, but after update and turning off TV, there is nothing shows on screen. I hear only sounds, and remote clicks, menu gone etc.
I search for info, and go back to v083 software, that helped and fixed TV. But now I don't know what to do to fix my TV. Tried to update with factory reset, nothing helped. Any tips how to deal with it ?
Next thing is concerned with soundbar thing, I have LG soundbar, is it possible to control soundbar over TCL's remote ? On my old Samsung TV it worked normally.
Here in TCL I don't see option to choose sound sourec (tv speaker/optical/hdmi), there is no option to mute TV speaker and move sound to soundbar. For now I use 2 remotes, but I want to use only one like in Samsung. I connected soundbar with optical cable to my TV.
Hi there. Trapped into same thing. After flash, I can hear 'bing' when you navigating in menu, backlight is working, but screen still black. Tried to flash V191(Inserted stick to USB2.0 with Update.img and plugged in with power button pressed). But got same thing. Led is blinking during i suppose flashing, but after that - nothing. Can it be somehow reset to stock or whatever?
you have to go back to 0.83
Turn off the TV, plug out the cable. put the drive into usb 2.0, press power button on TV's back and plug in power cord, if led start blinking wait about 10 mins to finish flashing. Sometimes you have to do this twice and TV will be ok.
Write to TCL support about your problem, let them prepare patch
Hmm... I have couple of questions then.
Does that mean v083 firmware didn't published somewhere?
And does that mean that we can't update 65p815 to any new firmware with Android 11?
what was your native FW ?
I tried to update to V191 which is on android 9, and update was failure. There is something wrong with the FW
File upload and sharing. Large file transfers. Free online cloud storage.
Visit this link to download: V8-R51MT02-LF1V083.zip
files.fm
here you can find v0.83
Android 11 is in beta now, we have to wait for official final update
I didn't check my original fware version. I know that was very stupid, but i supposed that just platform is matter.
Thanks for link. Will try this fware. Hope that will help, because i don't like to waste time with support, that usually just redirects to another operator...
it should, try second time if the first will failure
Ok, i just finish downloading and i'll start bring that baby to life. Thanks for help. Will report if suceed.
report it to TCL support to make technical request, and to fix that firmware
Ok. Just flashed twice. God damn, you have been right! All works like charm!
If someone will be as "lucky" as me, steps are next:
1. Load to local pc zip from above.
2. Format flash stick with FAT32 and copy it to root.
3. Insertt stick into USB 2.0 port.
4. Turn off TV power physycally.
5. Press and hold On/Off button on a TV's back and plug TV holding button pressed.
6. Hold for 10 secs, the led in front of TV will start blinking - it is ok.
7. Wait till it will stop blinking and wait some 5 mins after that.
8. Repeat steps 4-7. After TV restart it will show TCL logo and Android welcome screen will appear.
Ok now we should think about how to flash properly new version of FW,
latest official firmware is
https://www.mediacenter.tcl.eu/uploads/common/R51M_Android_P_V191.zip
When I try to flash with it, from menu update/local it works but only first time. When I turn off TV, then screen is black
I found such instruction, what to do after installation
Press the Settings button in the remote control:
Press OK on the icon: Picture.
Then go to the line Advanced settings.
Scroll down to the line: Brightness settings.
Scroll down to the line: Contrast.
With the remote control, do the key sequence: 6 4 2 5
The special menu appears.
Go to the line “Reset All” and press OK.
Go to the line “Reset Shop” and press OK.
Now unplug the main power cord.
Wait for ~2 minutes.
Plug back the main power cord and perform complete installation.

Seems on mine 65P815 by your table, the code should be ST6451D02-3 (code 305), but i have ST6451D02-H (code 283).
I have flashed v272 (img file) from v084 to my 65P815. Flashing went smoothly with no black screen ecountered. v272 works nicely with no problem.

@ancifil said:- "Did you reboot your TV after that?"
Sure I had rebooted it after flashing as I have been using this firmware for about a month.
I remembered flashing it 2 times. The first time was not successful (can't remember due to what). The second time reflash (same as what you did as in post #10) was smooth and without any problem.
jngiag, looks like it should, as for me... Maybe, i shall try 272 one more time.
superfly86, did you try 272?

Btw, one thing. Can you remember, after you had flashed 272 first time and after that launched flash menu, to flash second time, was you able to see menu?

I think it was due to a request to input pin while I was trying to setup live TV. I did not know the pin so I powered it off and reflashed as in post #10. Sorry, I can't remember it exactly.

Your 65P815 with panel ST6451D02-H...... Project ID MUST be 283.
This is your problem with firmware (black screen ) !
So you need to change ID number from 305 to 283.
To modify the project ID, when TV is ‘ON’, with the remote control do the key sequence
0 6 2 5 9 8 .....MENU.... 283.
At the end of the key sequence the TV must reboots alone if the project ID has been understood by the TV. If it doesn’t, update the product with the last software available and try again.
Sometimes several tries can be necessary for successful project ID modification.

You need TV to work back or worry about not to reset TV ?
First try to unplug TV from power socket and after 10-15 min plug back .
If not,you nee to flash PKG file, to boot normal again.
I have already tried and you have nothing on a 100% working pkg file, each I uploaded the TV stops on the android logo after 4 hours the same

Sharp Android TV storage space low error and boot loop after Android 11 Installation

My Sharp Android TV (4T-C70BK2UD) has had an update available for a while. In the spot where it used to say "update now" it said something about new features, which leads me to think it upgraded in the background to Android 11.
The TV now constantly resets, sometimes a google/android error pops up "storage space low"
I'd LOVE to figure out how to launch into safe mode / recovery mode / bootloader and wipe it clean for a fresh restart otherwise it seems like my TV is bricked?
Already reached out to Sharp Customer Service, and waiting for a response--- anybody have any ideas? Thanks!
