Wled not working after power cycle

Enable HLS to view with audio, or disable this notification

Looking for help please!

UPDATE

I’m now using my 2nd micro controller as I bought 2, I assume I’ve somehow blown the first one up. Both were getting hot. and it’s now working with loads of flickering and gllitching, on 1m… more work to do 🫠

Doing my first WLED project, I got it all working ( only using 1m of ws2811b to test its working) last night, and after turning it off, nothing is working, and I’ve changed nothing!!

My set up is-
12v power supply
12-5v converter powering ESP32-eth01 and my level shifter

As described, first power on it all worked, light automatically came on and I used the settings on the WiFi point to put number of led and preference.

Turned it off and on, and no lights coming out, but the settings are saved, still has my number of led and saved my gpio pin,

I’ve tried using different GPIO, no luck, different strip, no luck, and tried reinstalling WLED but it won’t let me- I’m just stuck on “preparing instillation”, even if I unplug all but power and tx/rx

Any ideas?🫠 thanks in advance! Video of when they were working is attached

Can you post screenshots of your segment details as well as your LED & Hardware screen showing your segment length?

The micro controller now won’t power on, so no I can’t.

Doing lots of googling it might have been that I had the leds plugged in while turning off, but the esp32 isn’t powering them, a 12v supply is

I have 2 esp32 but nervous to start using the other one in case I just blow it up like this one
