Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Do you know if there weer any power outages or thunderstorms whilst you were away?
Ok, then it is likely that the machine has suffered some damage from a voltage spike when the power was restored.
This is a common cause of this type of failure.
Do you intend to debug and repair the fault yourself?
Do you have a circuit diagram, soldering iron and other tools available to proceed with this, or are you looking for a repairer in your area?
Ok, but you have some experience in carrying out electronic testing, and you have some test equipment available?
Ok let me check if one of the other techs can guide you though this.
