My unit was doing the same thing after the move from CA to WA. I had to remove the mb and re-insert it to get it past the point that yours is at. Push real hard on the mb to make sure it is fully inserted in the slot.
And as I said in the Private message to you, try it without any drives. Also can you take a picture of the memory stick and email it to me at
dfullersnap@yahoo.com? This unit takes a very specific stick of memory- If I remember correctly it needs to be a parity stick -- not a non-parity memory. Also, what processor speed does yours have? It should be 766mhz.
Try it without the drives inserted as well. it does not like certain drives for some reason.
As I understand from your message that not even the system led will come on after you power it up -- is this correct?
ALso make sure the cable that goes into the digital display is good and tight(inserted all the way).
