dead ps3 with possible corrupt bios?
ok, i was trying to help a member
@monu1232009
who broke off his 4pins power connector from the mainboard.
i was helping him in private posts to get the wires soldered onto the right spots, i don't think he did it the right way, but at least ground and +5V are soldered right, so standby mode should work. (picture of how he soldered wires, the black marked points are from me to show he mixed up wire 1 and 2) ![]() he don't get a red standby led, although he measured the +5V and 3,3V at the power/eject board so this tells me the bios chip gets it's power. first the history of the ps3 : model :cech25 psu :APS-270 (pinout according to ps3devwiki: 1,switch on, 2 ground, 3 ground, 4 +5V ps3 was bricked due to installing 4.21CFW (green flashing light, no hdd or audio and video.) he tried to unbrick it using a e3flasher, and i don't know in what stage the power connector broke off. my guess is that the bios is corrupt, since there's no standby led present. (assuming that 5V from the psu is enough to have the bios chip function properly.) he's asking me if he can reflash the bios, but this is not my territory so that's why i am starting this thread, because i have to give up. i know @playerkp420 , @baileyscream and @Bigbones87 know probably the most about using these flashers. i can only focus on the power connector , pin 3 and 4 are correct soldered so 5V is available, pin 1 and 2 are wrong, but this would only mean a power faill on startup..... pin 2 and 3 are probably seperate grounds , 4 the ground for the +5V and pin 2 the ground for the switch_on input? pin2 and 3 are not visually connected either on the mainboard. hope to get some help here.

but the power supply should work like a pc powersupply. there should be main output power (supplied into the 2 prongs that the powersupply plugs into on the main board) so we can forget that. then a 5v + out a 5v - (gnd) out i assume point 4 and either point 2 or 3 is 5v- (gnd) and with just that you should get the red light on to say power has reached the board on pc's power supplies ther is a dead short on 2 wires to turn the power supply on propperly now the ps3 may do the same with say point 1 and 2 or it may send a voltage back up point 1 i would first try to get the red power light back on (power on the board) if the nor / nand has no firmware on it then the light will still come on so dont worry about that part for now. |

the system was bricked and the flasher was attached when he tried to restore power to the mobo. what if the flasher was not connected properly... and the bios chip which holds the boot up procedure i think, because power button, leds, blutooth, fan are coming from this chip. can the bios be damaged from installing firmware? , because if that chip don't start up properly then none works. ************* [ - Post Merged - ] ************* ![]() 1= switch on 2= ground 3= ground 4= +5V what i don't get is since pin 2 and 3 should be ground, that they are not visually connected, i don't have a board like that so i can't test anything, on my 60GB ps3 both grounds are connected. |

it's best we address that question to him.
![]() so, @monu1232009 , how did you broke the connector, was it when you tried to install the flasher? also did you corrected the wires, you seemed to have 1 and 2 mixed up. and from what country are you. |
