Why is my HP monitor blinking a green light?

  • After removing the defective capacitor, you must clean the holes before replacing it. When the holes are clean, you may insert the replacement capacitor.
  • Each capacitor has a positive and a negative leg, so make sure you place the legs into the proper holes on the motherboard.
  • The motherboard should be labeled to identify which holes are positive and negative.
