UP300 LED Light doesn't work

The led bar doesn’t work…
How can i check led, wiring,… ?

i follow : How to turn light on while printing?
But nothing to do…

Thank’s in advance.

Are you saying it never lights up, or just doesn’t stay on during printing even following that trick?

I say it never lights up !

Where did you buy it? I would get more information there, because maybe it’s broke or something is missing, that happened to me one time.

I think the light is broken… did you repair it ?
