The fault is when the ps4 starts there is no background music & after you go through the initial settings from it being wiped it 'hangs' for a while showing the controller & the charge level in the top left corner.
After just over 1 minute the screen goes black & that's it! you then have to hold the power button to shut it down & when you restart the ps4 you have to go through the setup again!

I've no idea what the previous owner did prior to the fault. It's definitely not hard drive related as the original one has been fully checked out & works fine.
My only guess is possibly the NOR chip has been corrupted in some way. Be good to hear your thoughts.
