250 Locked up with please wait on screen

[jrf]

Hello everybody,
I have a Konicaminolta 250 which has "please wait" on screen. I tried to reflash it with CF card. It will not respond to reset switch either. I am returning with novram. I also removed scan board Any other ideas please ?

CAUSE: Possible failed Scan board.
SOLUTION: Remove the scan memory board. This board is mounted on the MFBS and is the closest board to the flash ROM socket. If the machine will
come to ready when the Scan board is removed from the machine, then replace it (p/n 4551 2041 01 - PWB Assy)

or perhaps

CAUSE: MFBS board not properly seated.
SOLUTION: Reseat the MFBS board by sliding it out of the machine and back in.
