pfaff creative 1471?

I inherited a pfaff creative sewing machine 1471. It is in brand new condition because previous owner did not like electronic things and her husband bought it for her.

My problem is this: All the lights light up, but the display is empty. I can not turn on or off any of the lights. It is only 110 volts so it has no fuse.

Everything in and around the machine is clean; it has been kept covered.

Help I really want to use this to sew my wedding dress! thanks!!!!!!!
