26-108 leds freeze after a while of working, first 25 leds work ok

peter · 23. September 2016

Hi there,

I installed the latest hyperion (via hypercon on Raspbian). I have 108leds. After boot everything works but:
- Major problem: after a while whe trying static colors and effects, leds from the led number 26 up to 108 freeze (they stay at that color/effect) and I am not able to change them. I can switch just first 25 leds (counted from power cable side). I must turn off leds from power and then it works again for a while and scenario repeates.

- Minor problem: selected effect after boot is not working. For example rainbow will not glow after Pi boot (I am going to investigate this more, maybe it is just config file problem).

But whats wrong with my major problem?

But what leds you are using? Which config?

penfold42 · 24. September 2016

Have you checked the voltage on the led power supply ?

But what leds you are using? Which config?

I am using WS2812B (3 wires config) and rpi3.

Have you checked the voltage on the led power supply ?

yes, voltage and power supply is ok.

I would try running an effect like rainbow swirl fast and then try squeezing LEDs 25 and 26 - you may have a bad solder joint.

Try to press the white case rather than the gooey silicone bit

TPmodding · 25. September 2016

yes try what penfold said. and could you post your config too?

ok I will try it. Meanwhile here is my config:

ok
1. you use the old ws2812b type, should change to the new one -> https://hyperion-project.org/t…-type.82/page-3#post-3104
2. you use 108 leds in your config and wrote 150leds in the device section. is that right?

1. if I understand it good, I should change "type" : "ws281x" to "type" : "ws281spi", right?
2. yes, I should change it to leds:108.

try first the right led counts, may it works

If you change to the spi based led driver, you also need to change the pin it is attached to. The spi driver uses the MOSI pin (= gpio 10, = header pin 19)

My money is still on a hardware soldering issue

spi is not working for me.

My money is still on a hardware soldering issue

I made video of my problem - https://sendvid.com/6r45zllv. I have no idea why this happens, that after few minutes (approx. 3) leds no.26 and up stop responding. I resoldered all wires but it persists (so I don't think this is soldering problem). I must power-cycle leds to get it working again for a while.

penfold42 · 26. September 2016

I wasn't referring to you soldered wires.

I suspect there's an issue on the strip involving LEDs 25, 26 or the connection between them.

Does the strip have a join at that point ?
Some of the factory soldering when they join strips isn't great

bingo! I am currently writing you but you were faster. That was the point! I found out that there is a problem near LED 26. Interesting is, there is no join (joint) there. I am going to take magnifing glas to find out what's wrong. Thank you for your great help!

penfold42 · 27. September 2016

They can be tricky to solder - the packaging is really cheap and the manufacturer basically claims you can only solder them twice (cos they're so fragile )

If you destroy the led, just cut the strip and then rejoin it eliminating led 26

peter · 28. September 2016

thank you for the instructions, Penfold42!

Oh, I am having the exact same issue on my APA102 setup. Tried various things but coulnd't find the issue. Will look over the weekend if its a weak factory soldering too there.

EDIT: Weird thing is: this only happens when using it via Mediaportal. If I set it to display full white its running for hours without a problem.

the_stig · 2. Dezember 2016

Hrm, nope. Its a normal connection. Problem always starting from 6th LED of 2nd strip. Any ideas? Rick164 throwed a defective PSU into the ring.

the_stig · 6. Dezember 2016

Ok, answering myself here in case someone is interested due to similar issues. Had only around 3,3V on my 5V Strips. But PSU is delivering 5,4V, so its probably bad wiring of my setup from PSU to strips. Will redo these and see if it works again.

TPmodding · 6. Dezember 2016

is it to long?

26-108 leds freeze after a while of working, first 25 leds work ok
