Errore code 19 led shutdown

Hello everyone.

I am a hyperion beginner and initially I had no problems, but after 1 week I started having problems. I was able to use the ambient light for hours at a time, but today after I turn it on, it works for the first 10 seconds and then all the LEDs go out. This is my configuration:

RPi1 with hyperbian (hyperion version: 2.0.14)

Splitter HDMI:

Video Capture:

WS2812B led: https://it.aliexpress.com/item…B34j&gatewayAdapt=glo2ita WS2812 DC5V / Black PCB / 3m 60 IP30

The LEDs are powered by: power supply 40W/5V

Raspberry is powered by the following power supply: https://i.imgur.com/UGBWXXX.jpg

The splitter is powered by the following power supply: https://i.imgur.com/OjFoJwv.jpg

Video capture is powered by the raspberry port

This is the scheme of my configuration: https://i.imgur.com/7V5WqKE.png ( I made a silly drawing, to make my configuration clearer )

This is what I get in the logs:

I hope someone can help me

Thank you in advance!

(sorry for my bad English)

Ho trovato un altro RPi1, e ora non mi dà più l'errore 19 .
