Hi, It has an i7 3rd generation processor. Checked (LVDS_IG_PANEL_PWR = LCD_IG_PWR_EN) at U9000 Pin 1 but not voltage was present, could replacing with a new PCH (SLJ8E) resolve the fault? Regards. |

Is the fan spin? This measurement is done with the screen connected? |

This measurement is done with the screen connected? Yes with the screen connected. I even tested that screen with another working board and it works fine. The fan does spin at high speed after a few seconds of being on. |

I agree with lamo if after reviewing l9008 and l9004 and these coils are not open changes the LCD CONNECTOR and if this does not solve the problem then the PCH may be your problem |
