Could be several reasons ( cutting back too closely, dryness, cold wind damage, disease...)- but the bad news is that once a branch has gone brown it does not green up again. It might be a good opportunity to replace it with a similar conifer that doesn't reach the huge proportions of the leylandii and save a problem for later? Sorry to sound so gloomy.
