I installed a 5m strip of Sk6812 on the back of my tv a few months ago and has been working flawlessly with no level shifter until a few weeks ago. Only the first 6 LEDs are responding, I asked in the discord and some people suggested using a level shifter and I got sn74ahct125n and wired it as so (except I am using a D1 mini with D4 as my pin
But this didn’t solve the issue.
Then I tried hooking up a new D1 mini to the strips so I flashed and connected the LEDs to a new module with no difference.
I do want to note that when this issue started to arise the LEDs will just freeze up except for the first few and touching the malfunctioning made it work until it happened again (not that often). Then a little while after it would freeze up but touching the malfunctioning LED will only change the colour so the effects didn’t work at all, so I asked on discord. When I installed the Level shifter I tried touching the malfunctioning LED but nothing would happen to the malfunctioning LED.
Is my strip already dead or are there other things I can try like somehow testing which pixels are dead or replacing/jumping pixels?
