tried everything... Galaxy Note 10.1 2014 edition has just stopped charging

I literally have tried everything.. different charging cables, different outlets, etc. just 2 days ago my tablet which was charging just fine has now stopped charging no matter what i do.
do need a new battery? if so, how do I do that? could it be the charging plug on the tablet itself that went defective? if so, what do I do then?
is it time to buy a new one? Please help! I live on a small island in the Caribbean and do not have a lot of repair resources.
any ideas?
Thanks in advance
