Hi; My PS4 Keeps turning off every time I turn it on; sometimes after 2 seconds and sometimes after long minutes of play; would you please assist on that?
Try replacing the power brick using this guide, if that doesn’t work then you are dealing with a GPU/CPU fault and it’ll be more cost effective to buy a used unit than to repair.
It may be because of overheating. Clean out the fan and replace the thermal paste. I’m currently waiting to get some thermal paste
