Today I re-did the thermal paste on my PS4 Pro and now it won’t turn back on. I have the similar issue where it flashes for a second and then dies. The fans don’t kick on but the eject button is working. I also don’t need to unplug it but need to wait a few seconds in between trying the power button again for it to respond. After I did the thermal paste it did turn back on but got to the login screen and froze up completely. Since then it has only done the mentioned on then off. I don’t want to purchase a power supply if it will not fix this so is anyone confident in saying if this is a PSU issue or caused by my APU? Thanks!
Hi Brandon! Before you replaced the thermal paste it was all OK ? Are you sure that everything is connected as it should be? And check if there are screws missing, perhaps some screws fell in the PS4 which is making a short. Also, be sure that the heatsink is making contact. So far it does not sound like a PSU issue.
