Have you got any AC? at live and neutral contacts (be careful, I hate mains,

).

Or power it on and off then check the main smoothing cap (if you can access it). See if there is residual voltage on it.

If you have no AC, then it has to a fuse. Or something associated with the mains input.

EDIT:- can you see how the clock is powered? could be a standby circuit fault.
