PS4 not turning on, power supply already changed
I bought on the Internet a broken used PS4; the owner told me that he went on vacation and, after 2 weeks, the console wasn’t turning on and so he decided to sell it.
The console was never been opened and so I decided to try and change the power supply with a good working one. The console still doesn’t turn on and it won’t beep even shorting the “pad“ on the mainboard with a screwdriver.
Considering that there is not any schematic document for the PS4 on the Internet, would you please help me identify the problem and maybe tell me where should I begin to check things at component-level?
Thanks in advance.
Is this a good question?
