in my current project, I'm controlling a SK6812 LED stripe having 300 (- 1 ) LEDs using an ESP32 (Lolin D32).
The setup is quite simple: The 5V Power is supplied by a 100W Meanwell LRS-100. Using an LDO to get the 3.3v for the ESP32 and controlling the stripe using these 3.3V (I know this is not ideal, but it seems to work without a level shifter). The stripe itself is powered directly from the power supplier. Since I had some flickering towards the end of the stripe, I am now powering the stripe from both sides and using the same power supply. Parallel to the supply I have added a 1000 uF cap as suggested by some manuals.
Now, already two times when I unplugged and replugged the power supply from 220V, my first LED in the stripe died such that the whole stripe does not work anymore until I remove the first LED.
Do you have any Idea what could be causing this and how I can prevent it from happening.
I have already measured the power supply which delivers 5.1v
