ghd's not working,due to been dropped.pink ghd's model ghd 3.1?

i was using them yesterday and accidently dropped them on the floor.
i then noticed the light went out, so i then switched them off and allow them to cool down, once they did i switched them back on again and they didint heat
up again. my husband did a couple of tests on them and he said there was power going to the elements but nothing going to the fuse, ( the one inside the
straightners, not the plug fuse ) so we are thinking its not a big problem but its one we can't fix,

could it just be that the fuse inside the actual straightners that needs replaced?? power going everywhere else but to the fuse inside.
