It appears you need a C4788-60511.  Here's a refurb for $129 + shipping.

Yes, there's certainly a decent chance it's repairable.  You might
even get lucky and discover some sort of blown fuse.  I can take a
look at it, but Keith should really be your preferred repairman, if he
has the time.  BTW, I don't recommend poking around by yourself.  It
could potentially bite you.
