Chosen Solution
So basically I just finished cleaning out my heat sync and all of that. But, now I try to power on my ps4 but it turns on and shows a white light but then the fan speeds up and the light turns red and then the ps4 shuts off. I got some of thermal paste on my finger because I touched the paste that was already there and I think that’s what’s making my ps4 act up. I just ordered thermal paste. So should I fix the thermal paste? or is it another issue? Please help
Old thermal paste can’t be reused. Need to replace it with new thermal paste like Arctic silver 5 or equivilant. Make sure to verify that all thermal pads for the VRMs are present there’s roughly 8 of them I believe? Also make sure the clamp with the two large phillips screws is not upside down, the ends should be facing up.
My recommendation would be to unplug the PS4 from everything, wait 10-30 minutes, then securely replug only the necessary plugs (TV and Power. Don’t do the ethernet cable if you hardwire or any other accessories). Then try to boot it up again, either normally or in safe mode. Can you get to the safe mode menu to do a full reset? That may also help since your databases and probably pretty grumpy now that they keep being rebuilt. I’m obviously not a tech expert. I dropped my PS4 once and the plastic case fell off and I managed to snap it back on and that’s the extent of my repair capabilities.
