  1. Hallo. Could you tell at which capacitors you get 2 sparks? I just receive new motherboard from China, connect it, turned on, and I have abnormal printer behavior. Led screen is off, and and all motors vibrating.
  2. Hallo! I had the same story. Only main fan is working. But computer can't find printer, screen is black, LED is not working... I just trying to find a person who can test motherboard... If it will not succeed, I think motherbord should be changed.
  3. Dear community. One day I realized that my UM2 do not start at all. Power supply is ok (i check it, 24V). When I push ON button, only main fan start rotating. Screen doesnt work, USB doesnt work, LED doesn't work. All cables connected, and there is no visible burnouts on the main board. Please support what I can check?
