Random flickering in leds then it freezes

[Suspect-byte]

I have an RPi 3B running HyperHDR, connected to a HyperSerialPico using a Pimoroni Plasma 2040 with SPI. I'm using HD107s LEDs. Everything worked fine for about three months, but now the LEDs have started to flicker, and after a while, they freeze. I cut the power and restart using the power supply, and it works again for about five minutes before the flickering starts again. I've already swapped out the beginning of the LED strip and changed the wires. What could be causing this issue? I think it may be the powersupply

Hi
If you restart the LED device in HyperHDR (without touching the power supply) does it help? How is the manufacturer of the LEDs?

[Suspect-byte]

The manufacturer is KINGGREEN. So it is a decend brand i think. Now i doenst work at all anymore sadly.. It gives 5 volt with the multimeter and no short. Resoldered everything added the ground from the pico to the ledstrip and to the psu. Reinstalled hyperserialpico and hyperhdr. No it doesnt change anything sadly when I restart the led device in hyperhdr

You didn't have to reinstall the software: if you stop the LED device, there will be statistics in the logs that show whether there was communication or not. If you have the possibility, connect one LED to the plasma output to check if it works: you can power it directly from the plasma

[awawa-dev]

BTW Force ESP/Pico Detection : ON this is unnecessary for your board but unrelated to the main problem. Better to disable it.

[Suspect-byte]

sadly still nothing. Changed the force esp detection to off. Connect 1 led to the pico still nothing but this is my dashboard. I see this with a small bin logo

[awawa-dev]

this one led does not work either? what's in the log when you enable/disable the led device few times while playing the effect? this bin logo is a symbol of dropped frames. not sure what's the reason...maybe something will be in logs.

[awawa-dev]

take a look into dmesg logs also

[Suspect-byte]

Okay i changed the leds again. It works like a charm. But after like 10 seconds it starts again flickering and eventually it will turn in full white light. It works also on the pico 1 LED.

[Suspect-byte]

The bin logo is gone. The Logs are exactly the same as before. It says undervoltage, but that is impossible because the rpi 3 is getting power of a 36w power adapter 5v ofcourse

[awawa-dev]

Unfortunately, it is possible and happens quite often when powering the RPi from an LED power supply because its output voltage is unstable and fluctuates. I don't know if it is the cause, in any case it is the only clue so far. Another possibility is that the LEDs are damaged or the ground connection has been broken somewhere on the tape in the corner.
