CR - Laser Falcon 10W not working

Hello. Not sure if this is the right place, but I have seen people ask the same question as me over here.

My Creality Laser Falcon 10W is not working. As I turn it on, the fan on the laser starts. It immediatly beeps 2 times, then it shuts of and goes into breathing mode. The green light on the laser is on for just a millisecond, then it turns off. It sounds like the motors engage for a splitsecond, then it stops and starts the beeping.

Even if I don’t have anything loaded onto the TF card it still does not work.

Is it possible you can find a substitute power supply? If that is not it, my guess is the controller board might be bad. If it will not stay on, it will be difficult to flash the controller with clean software.
