yes still same led strip.. yes maybe more pf them is burned out.
now i have the right power to the strip.

I have fix a new 5V mean well. 4K splitter and a HDMI/usb capture card instead of the analog usb/RCA to test with.
Only the first led is lighting(green) nothing more works for me. (ws281x)
I can se the liveview in hyperion and thats the same as my screen.
have i forgotten something?
I have allready cut THE first led.

Dtparam is fixed.
I see the picture of the live stream in Hyperion and set it to 720*480
Nothing more happends. I have fix a new 5V mean well. 4K splitter and a HDMI/usb capture card instead of the analog usb/RCA to test with.

give me some help!
now im in again..
all settingt with dtparam and so on.
the leds are working but only the first led lights green.. nothing else happends.. in live view i se same pics like the tv
tnx =) then i will power the strip from both ways then i get the new mean well =)
i have fix capacitor for safety
do i need a 100ohm resistor between datawire and gpio 18?
nope =/ do i need that?
now i have order a mean well and capacitor 1000uf
do i need to connect both end of the strip or only one side to power supply?
i have look at a mean well LRS-75-5. 5V 14A
you mean controll that the gpio 18 works?
the strip and the rpi have there own powersupply so i dont think the pie gpio is bad.
when i messure between ground and gpio 18 its like 2.2v so its not dead
how many Amps do i need for 198leds? ws2812B ?
some say like 17A another max 10A.
and do i need a capacitor 1000uf?
hey guys!
im new to this and i have follow some treads about building a own ambilight.
ws2812B
198 leds behind my TV
im using a rpi 3B with own adapter.
hdmi splitter 1x2 1080p
usb capture card to rca
hdmi2av
so!!
yesterday i get the strip to light up with hyperion, but now its totaly dead.
the strip is connected to gpio 18 at the Rpi.
it has it own powersupply ( computer powersupply)
when i check the +5v at the powersupply it gets 5,7v (29A max), maybe it killed the ws2812B ?
some people says i must have a type of resistor between the +5v at the power supply and the strip but i havent use that.
can i controll the strip at any way? i dont know if the whole strip is dead or only the first of the leds
