Hello, i'm having problems with this corona board that will beep and green light but turns off after 2 sec.
1) I don't have 3.3v standby voltage at all pads of connector j2c3, the 3.3v/1.2v regulators are replaced and ok
2) Measured voltage when console tries to power on at the mosfets near cpu area, only 12v for a brief moment then console shuts off. Can't get any other voltage in that 1-2 sec that the console is trying to power on.
3) I've reflowed the ksb/southbridge, no difference.
Do you think its a ksb issue because i'm not getting 3.3v at that connector near it ? or maybe a bad mosfet? (how do i check this?)
