I bought used fat ps4

Hi I'm new to this reddit I have little knowledge about electronics from watching YouTube videos

So the ps4 does turn on blue light and fan sound Seem like the fan is okay not very loud

But theres no signal

HDD works I tried it on the laptop

USB doesn't seem to recognize the ps4 controller so I'll assume that it doesn't work

Previous owner told me that the main problem is the HD

I have a theory that the device power supply is changed and that broke the USB and the HD and the obtical

Cause I tried to plug a speaker in the obtical and theres no sound

Any suggestions?

Edit: if I unplugged the device while its running the blue light remains on for a few seconds Is that normal? I know its normal on some devices but for ps4 if its not normal its very possible that the power supply is not original

Classic Blue Light of Death. Something is stopping the device from finishing its boot cycle (when the light turns white). Enable UART (you need to reprogram the NOR for that) and read that to find out, it's likely a lost cause.
