Hello. I have a problem, where my PS4 will beep once, with blue light flash, but then it turn off. I’ve tried the answer found in a similar question posted earlier, but nothing work so far. Things of note: It can actually boot normally, if I were to unplug and drain the remaining electricity. I rarely use my ps4, and I did manage to boot it up without problem a few days before. But once I update to the current firmware 7.5.1 (from 7.5.0), the problem start to occur. And I’m guessing it’s the root of this problem. After playing with it a few days before, then turning it off, when i boot it up again, the problem occur. When I unplug, and successfully boot it, it acts as if the system was not shut down before the point where I pull the plug, despite a night has passed (showing me the screen warning against pulling the plug when the system is still in used when starting up). This actually also happen when I put it to sleep then boot it again- I tried to drain, and boot it in safe mode, to rebuild its database, but the problem described above happened, and now if I drain and unplug it again, it show the “checking hard disk“ screen, then loop back to the problem. I’d appreciate if someone can give me some suggestion on what to do with this.
Hi! Almost certain that your PSU is dying. You need to replace it. When it turns on, shows the blue light for 2-3 seconds and then turns off, is (mostly) caused by: PSU. Power supply failure.APU failure (needs to be reballed). As your PS4 is still able to boot.. My vote goes to defective power supply (this one is easy to replace and lower in costs).
