Could you post a picture of the board?
Maybe there is a soldering error some where.

Hi,

I can’t really see the solder side of the board.
However it looks like it maybe wired wrong it looks like you may have the blue wire and the black wire swapped below is a picture of the manual.
Let us know what you find.

i swith em becouse the blue is wire to the 12v on the led and the black to the blue else it did emit light at all

Could you post a clear picture of the solder side?

Just had another thought.
Do you have the right firmware loaded?

i downloaded the latest firmware from the website and but it on the printer and i can se the led controler on the display

Once again this is not a good picture.
Try taking the picture looking down on the board.
Please make sure it’s in focus.

I dont know if this is a double sided pcb, but u didnt solder the top. I see mosfets that are not soldered on both sides

It’s a single side board
