Then I modified the script to fit the nodeMCU Amica esp8266mod 12-f. For the WS2801 I put RGB colours as order.
Now everything works! Congrats on the superb work and thanks for the support!
I'm attaching the modified version of the .ino script if it helps anyone.

great job

It happens to me that during the night, when the tv is off, all the green LEDs light up. I turn off the power to the LEDs, put it back on and they stay off. Then when I turn on the tv, they initially work fine, but after a few minutes, everything that should be black is displayed in green. I have to turn the tv off and on again 3 or 4 times for the problem to go away. Has this happened to anyone before?

Any chance to see it working on DEU firmware? ( ue48h8000 tv)

Is it possible to make it work on the J series?

Hi everyone! I don't know if it's my problem or a bug. it happens to me that when I turn on the TV, after a few minutes, the LEDs remain fixed on the white colour, it always happens when the projected image is white. I noticed that the esp8266 is completely blocked and no longer responds to any command. I have to unplug the board and plug it back in. then it continues to work fine. the esp is powered by the same power supply as the leds. I also noticed that when I raise or lower the volume with the remote control, the LEDs seem to flash. I don't know if the two things are related. is it my problem? of power? or code or TV?

I think i fixed it!
From the power supply I made two different cables come out. Not as seen in the first post.
One to power the leds and one for the esp8266. Then I connected the GND PIN of the esp with the GND of the leds, so that there is no flickering. Now i have no more problems!

Hello, Hello, Is it possible to make sambilight work on TVs with Tizzen operating system? I have a J series TV and would like to install sambilight on it. thanks.

It is not possible.

OK thanks. But now, what's the reason?

Because i don't have a J series TV.
