My ps4 was working until I decided to clean the dust inside because it was very loud. After cleaning everything, I put the ps4 back together. After plugging back in, when I turn it on the blue light comes up for one second then the ps4 turns off. not sure why it would be a problem with the power supply if it was working just before o started cleaning it :( plz help
Recheck your psu is plugged in properly, the fan is plugged in properly etc. Also check your thermal paste.
