Yep check fuses first then try disconnecting the battery and reconnecting see if that resets it.
Failing that there is a common fault where the wiring behind the dash binnacle can rub on one of the metal bars causing it to short, maybe worth giving that a check. I suspect it will all come back to life unexpected though and you will wonder what that was all about.
Usually the case having read people's accounts over the years. It is probably the wiring rubbing behind the binnacle that is the problem so when you get chance I would pop the clocks out and have a look.
