Some countries have laws about repairs. In my State we have the B.E.A.R. which I would be contacting about no repairs.
That said, some repairs will go B.E.R. (beyond economical repair) if the failure is the panel or a big board.

I owned a note 5 since it first came out to US market in Oct 2015. Its only pass an year with 2 month. I did not purchase extended warranty nor have insurance but I make sure I keep my phone good. I was just regular using it like facebooking, youtubing and etc. On 12/12/16 morning, it just wouldn't respond to any charging (both wire and wireless) at all... I called Samsung customer service and they referred me to a bestbuy. The bestbuy was not able to fix it because they told me it was the PBA (the main board/mother board) became bad.. Like I mentioned before, I keep my phone very well as I know I did not buy extra warranty or insurance. I did not drop it or water it or whatever physical damage it and the motherboard just become bad out of nowhere.. I called Samsung customer service again telling them the bestbuy was not able to fix it and they told me they have removed their repairing department therefore they do not repair cell phones without warranty and they cannot do anything about it. I asked if I can speak to a manager if he or she was able to give me some options and then they just hung up on me. Now I am just going to be stuck with a note 5 that's just 1 year and 2 month old.. I have been a loyal customer to them as I used note 3, note 4, to this one note 5 and this is how they treat their loyal customer. Very disappointed..
