Laser is not work

I just had my laser for 3 months. no problem until yesterday.
I turn on my laser, the movements of the x, y work normally, but once I launch it, nothing works, an orange led lights up (pmw) and a green led (key) it signals after a while the apareille extinguish.
Can someone help me please.
Thank you

I sent you a video explaining my situation.

I think the motherboard above the laser is causing the problem

Who did you send this video to? Ortur I hope (what you’re describing is a hardware issue and not a LightBurn related issue).
