I had this problem before. I was the MFP board. located on the left side of the machine next to the power supply. It could also be the NVRAM.

remove the fax board and accessories and try again.

NVRAM. Had exact same thing happen. Reset it or replace it. Keep in mind that you have to resetup the machine either way.

yes it is the nvram,pwb-m (next to the power supply)and last but not least the pwb-C in the scanner also.
the pwbm will have the center ic blown out of it.
