The Sun's "The FiX Factor" is the headline for a story about the TV show "The X Factor", which following one of the judge's refusals to cast a vote is facing accusations of being "fixed".

In this context the word "fixed" has nothing to do with something being repaired after being broken.  Here it means  making certain that a competition, race, or election is won by a particular person.

You can hear this in use in one of my favourite songs, which I will dedicate to Burma's military leaders.  The Fix Is In.
