The blue light of death... No screen no safemode no boot

I've had my Samsung up and running for about a week now , did the two most recent updates . Today is the first time I experienced some serious problems . It started with a fingerprint scanner not working delivering an error message that read "fingerprint scanner has stopped working restart phone if this repeats" so after my second time of dealing with this there I restarted the phone . P at this point in time is when the blue light was lit up and has stayed lit up since I restarted it, this has been about an hour. I've tried every option on the recovery menu except factory restore. When I turn the phone on safe mode or not it goes straight to a black screen with the blue light continuously lit up . When I turn the phone off the light never turns off . I've tried hooking it up to the charger and doing all of the same steps above and still no luck. I have not installed any unknown apps other than ones on the play store and haven't had time to even explore rooting or ROMS yet. Seems to me like a brick by the stock software don't know if anybody else's experiences but I don't know what to do . Maybe someone can shed some light before I consider doing a factory restore , if that will even work.. I think this thing is bunked.
