Hi guys …I just got a ps4 from my friend and he said it worked….I took it home and plugged all in and all….it would power on and beep and all…the hdmi was broke so I replaced the motherboard and put paste and all and I went ahead and replaced the power box motherboard too because my old one had roaches in it…I cleaned everything and all….now I plug my PlayStation in and I have no beeps no power or anything all it does is turn the fan on for about a second and stops…..any ideas on what this problem could be???
