Edit : With multimeter I have 5V everywhere on the LEDs strip

Did you measure while the leds where all on or all off?

I've measured both, while were all on and all off but I'll made new tests saturday or sunday, I'll have more time

I don't know if it's a data wire problem, a data send problem, a power supply problem or a hardware problem

Hardware is probably hardest to test.
I've had issues with blowing up the WS2812B from the start, which was related to ground. My casing is from metal, and that seemed to cause issues. First used duct tape, and 'glued' the LED strips on that, which fixed the problem.
Then i was having issues with the colors, even though i also had 5V on the entire line. I've hooked up +5V on every strip, which helped a lot.
The last thing i changed was my Data line. This was about 1.2 meter from the first LED in the beginning, and when i reduced that size to about 20/30 cm. all the problems were solved.
So long story short:
- Try to shorten your data line
- Add multple +5V lines to your LEDs (4 (for every side 1) would be best to test/rule out other issues).

4 for every side? You crazy man! Thats like 16 lines!

Post crossed the edit

But yes, normally i like to be 'powered UP Up up!'

Thanks for advises
I don't think it's a ground problem, so I'll add a 5V at the end at least and perhaps to every strip. Also if it doesn't work, I'll try to change data wire between every strip (my data wire is about 10/15cm from the first LED). And if it doesn't work anymore, I'll go to buy new hands
I'll try to look at this at the end of the week and I'll let you know my result.

Just a FYI to everyone using OpenElec to build the Hyperion setup, in its latest version which is 5.0 at the moment Hyperion doesn't work so best to stick with 4.2 for the time being.
Updated first post to reflect that and once the Hyperion developers update their package I'll let you guys know.

Thanks @Lightning303 for testing it under 5.0 and debugging

Could you give me examples problem ? I don't think it's related to my LEDs problem but it's to be sure.
