What would cause my Galaxy S4 to turn off and not come back on?

I have a refurbished S4 by my carrier that is now acting up and turning its self off and not wanting to come back on. It will start to turn back on and go to the Samsung logo but then turn back off. It is now fighting me to just do that. I have tried putting it into safe mode and the person i talked to with both At&t and Samsung said that it was not something i put on the phone, does any one know what could cause this and how to fix the issue. (i thought i had it fixed by putting a piece of paper at the bottom of the battery, this had been suggested by a tech, i just am very frustrated that something like this has happen twice now. :/ just really would like to hear anything anyone can offer or has to say
