TCL Android TV model 55p8m / Android Recovery TCL/BeyondTV/BeyondTV

[darkpoet78]

Initial seemed ok until I went to play an ATMOS sound stream in Kodi which crashed the soundbar (Onkyo inbuilt).

After a TV reboot, I tried and repeated the issue.

Trying another program, Plex, Atmos worked.

Haven't had a chance to test more yet, but I would hold back on v718 for now if you haven't already updated.

On V715 here with a 55P8S (R851T02) and this drove me crazy trying to get my Odroid N2+ Coreelec (Kodi/Jellyfin) to work. It seems like this TV just doesn't can't handle certain Dolby streams. It wasn't just Atmos (but at this point I can't remember which... if I recall, DTS and 5.1 and 6.0 were fine). Took me freaking weeks to figure out why the TV's display would just crash... while the audio continued to play.

I fixed it by going into Kodi settings and force-reducing all audio to 2.0 stereo... might as well since I don't have a sound system. If I ever do, I'll just have to feed it directly from the N2+.

Strangely, Jellyfin android app on the TV Android works just fine. I'm guessing the TCL Android handles the reduction to 2.0 stereo sound...

Just putting this here with the hope it helps someone else.

Edit: originally stated 55P815 when it's not.

You are mistaking the culprit

Audio issues on 4k

I’m trying to get my new N2 up and running. Most everything is going great, but one nagging problem is that 4k streams are causing a challenge. Video is coming through without an issue - and looks great - but audio is strangely, and consistently, missing vocals. Oddly, background music is...

Actually I'm on a 55P8S which I had assumed was similar. Now that I look closer at various specs, it's nowhere near the 55P815. Pretty sure I'm on the right firmware since my factory firmware was V8-R851T02-LF1V634.018640 and I read this thread for days before making the leap. Consider that an 'oops' in typing. I added an edit to my previous post.

Looks like a related but different issue. That poster was getting garbled audio. My video would blank while sound continued to play. At first I assumed the HDMI cable was an issue so I upgraded to a proper 4K (or 8K maybe) cable. I still think perhaps the HDMI input is just being overloaded since reducing the sound to 2 channels probably frees up some bandwidth for the video... but I will keep this in mind.

So, next time don't post other TV model.....55P8S and 55P815 is not same.

I have a 75C815 on 722. It also jerks a bit on high speed scenes….the processor just isn’t up to it…but I can’t really complain for the price of the TV.

I have also turned off all motion/clarity settings and uninstalled a lot of the pre installed apps (see prev posts on how to do that).

It also fixed some HLG artefacts I had.

All in all i classed it as a good upgrade.

Can you guide me a bit on how to do that ; i used ADB gui to uninstall some apps but when i powered the tv down and then powered on it went through the initial configuration wizard and i found that the apps were reinstalled automatically

Have a look on page 162, that is the one I used.
I chose not to remove a couple of items that I use as well.

witch one its for 50p8m model

 

[Cinam]

My understanding is that v722 in that link is for that model

That is the img so a complete install

 

[kareem007g]

where i can i identify this (v722 ) is it on motherboard

 

[Cinam]

V722 is the firmware revision.

Normally you would go into the settings and about to see what you have, but your TV is in a boot loop right?

Earlier in this thread, 50p8m is linked to the same firmware type, so it should work.
And worse case you simply try another image from earlier in this thread

 

[kareem007g]

i downloaded the v722 img .the installation started but process note complete and the tv keep restarting and repat the then restart installation but never finish . so i tryed v662 the screen show up start installing then shutdown .now i can not enter download mode .

 

[Cinam]

Try a different usb stick/drive and make sure it is formatted FAT32

If that doesn’t work, you may have a hardware fault on the TV

I had a similar Audio issue with my 43P8 and I updated it to V722 now am back at V634 as that was the last update that I got officially working on my ATV which is Android 9, I wish to update it to Android 11, however, the audio bugs needs to be fixed so no point of updating till that version is officially released.
