    PS3 Slim Turns OFF Immediately After Turning ON

    Hi, my PS3 Slim (CECH-3003A) when I connected to 230V the PS3 the indicator of the switch is red and after pressing it the is green (fan spins) for only 10 seconds and then completely off. Some times also is completely off when I connected to 230V.
    On the CN101 connector at the 5VSB pin I measure 0V.
    Without the CN101 connector pluged in the PS3 board (on the fly) I am measuring 5V on the 5VSB on the power supply side.
    On the 5VSB in respect to ground I am measuring 6 Ohm resistance. There is any schematic to find which ICs supplied from 5VSB or any suggestions where l have to measure?

    You are not measuring the resistance correctly; if there were 6 ohms on the +5V SB bus, the indicator would not burn out and it would not start at all.

      Hello,
      I measured it again... 6 Ohm between these two pins. Now when I connected it to the 230V the indicator don't light and the PS3 doesn't start at all.

        Well then, it's a completely different matter, apply a voltage of 3-5v 1A to these terminals from the laboratory power supply and increasing the amperes, see what heats up, then the culprit for the short circuit will be, most likely one of these 4 ceramic capacitors (it happened to me 2 times) .

          If you please could you tell (draw in picture) me which capacitors do you mean? Thanks for your reply and the guidance.

              Hello, with thermal camera I found that this IC regulator (RT8057GQW - SMD Mark: J7) was shorted. As I read on the internet this regulator was responsible for the WiFi & Bluetooth supply (please correct me if am I wrong). I removed it (without replace it) and the short was gone and the PS3 starts and shows image. Many thanks lotas.

                Yes, there was such a thing (it also had it once) this is a regulator from 5v to 1.8v for the wi-fi module. If you do not replace it, leave it as is, you cannot update the software (there will always be an error in the wi-fi module).
