Fired up the laser tonight and the Control Panel no longer powers up. Only 24 days old.  
No lights on the controller LED either for it. Check wiring to controller all tight and good to go.  
Can’t even upload a video to show whats going on ?!?.

You can check whether the 24V voltage of the motherboard is normal.  
If normal, there may be a problem with the external voltage
