The cache is NOT at the posted coordinates. In order to obtain the final coordinates you must find them in this list of some of the shows I've watched. They are not necessarily my favorites but are the ones that fit this puzzle!
Fam
Riverdale
NCIS
Deadwood
24
Revenge
Soap
Sherlock
Arrow
Mash
Dexter
ET
Mom
Friends
The final location is in a pretty busy spot so be on the watchout for traffic and muggles. Good luck and happy hunting!
