PS4 BLOD's Just sometimes.

Hi, very recently my PS4 started to not power up correctly and goes into BLOD. I did some research but I still don't know if it's power or Apu related since sometimes it works flawlessly, sometimes it just needs a reboot, sometimes it powers up but then loses video output midway. It is a 1004A model. I don't have the equipment to reball a chip, but I can do most else.

I'd be very grateful to who would help me!

Thanks in advance.
