3D printer not working

3D printer not working

My flash forge dreamer stopped in between printing. Now only 1 fan is working, no display no light , what could be the possible solution?


Probably a failed power supply board.

changed the power board but still only 1 fan is running. no light or display is there.

This is a challenge for us referees : :slightly_smiling_face:
I will refer to the block diagram and schematics. You can do that too.
Wonderful way to explore and learn.
