OMG. That was it. Thanks so much.
Just for understanding, can you explain why?

Sorry, don't understand what you mean. The stripe has 2 + and 2 ground cables (beginning and middle). But there is no ground connection between the Pi and the stripe.
I've found 2 potential issues:
- Pi and Stripe have 2 separate power supplies
- Data/Clock cable between Pi and Stripe is not shielded, but it's in a tight cable cover with 220v, 5v and ethernet.
Is one of those the potential source for the flickering?
Thanks a lot

Additional observation:
- LEDs are flickering uncontrolled in different colors only when Data is connected to Raspi, even if the hyperion service is stopped
Hello Hyperion Project forum
First of all, thanks for this great project. When I saw this the first time, I knew it's gonna be on the back of my next TV.
A week ago, it was time. I bought a new Sony 75" and all the stuff I needed for my hyperion setup:
Raspberry Pi 3B
10 Meters of SK9822 (similar to APA102) LED stripe
15A power supply
and a lot of cables, connectors and everything else I needed.
My plan was to use Hyperion Android Grabber because my main source is DRM free IPTV.
Everything was set up, and it worked like a charm. I was waiting for my new soundbar to arrive, and two days later the TV was mounted to the wall. That where the problems began.
- I can turn hyperion server on, I see the hyperion colors but the flickering is overlapping
- The LEDs are flickering uncontrolled in all different colors
- The LEDs are not flickering when Data and Clock are not connected to the Raspi
- The LEDs are flickering when Data and Clock are connected to the Raspi, it doesn't matter if the Raspi is on or off
- When I disconnect everything after the first segment, the first segment is still flickering
I have:
- Tried 3 different Raspis (all model 3 B)
- Reinstalled Raspian and Hyperion in total 4 times
- Checked all the cable and corner connections at least 15 times
- Replaced the first segment
I'm going nuts about this. I don't have enough stripes to change every single segment
What is making the LEDs flicker? Do you have any idea where to look next? I want my Ambilight back
Thanks in advance and best regards
