Is LaserWriter LS dead?

My LaserWriter LS is not powering up when turned on.
*None* of the lights come on. This happened out of the blue.
It was working fine two days ago and when I turned it on
yesterday nothing happened. I do not use the switch on the
back to turn it on & off. I have it plugged into a switched
surge proctector and have used that switch for years.
I did try plugging it directly into a wall receptacle and
used the switch on the back. Printer acts like there is no
power getting to it. Does the printer have a fuse of some kind which could have blown?
