I am not sure where you are located and though I don't know the answer, I think I would find out if there is a dealer and or technician close to you. Or even over the Internet find the number and call the actually dealership and see if they can give you any ideas to try. We have a tech here that works on all machines and is quite well with all of them. I will be stopping in there Friday,if he's in I will ask him what he thinks. My uneducated guess would be maybe bad computer board.....
