If at all possible - go for Panasonic or Nichicon brand, low ESR types in
105C rating.You will probably have to order them from Digikey or Mouser.
Make sure to get the same physical sizes as well as DC voltage and uF ratings.
BTW
I have found it a great advantage to remove ALL power from set top boxes when not in actual use.
