    820-4924 - No Backlight

    Clean board and I can see the apple logo, however, no BL. Already replaced the U7700, but still. I do have the enable, nut 0V on the PPVOUT_S0_LCDBKLT. W/ the screen Plugged: U7700: Pin 5-18 = 5V PPVOUT_S0_LCDBKLT = 0V / Diode Mode 0.31 PPVOUT_S0_KBDBKLT = 5V BKLT_EN_R = 3.2V LCDBKLT_EN_L =...

    820-3787 - NO S4

    The board had a short on U7501 on PIN 23 and 24 I replaced the U7501 and i got the PPBUS_G3H back, however, i dont have PP5V_S4. Here is some measurements: PP5V_S5 = 4.9V PP5V_S4 = 0V PP5V_S3 = 0V PP3V3_S5 = 0.9V - Diode Mode 0.077 Any hint, helps. Thank you

    820-00840-A - PPVCCCPU_S0G

    Here is the issue: I have all the rails... After 5 sec the PPVCCCPU_S0G 0.947 drop to zero. The CPU gets hot, but no USB or VIDEO activity. I already re-program the bios, replace from a good board and nothing work. Any hint at this point?

    820-01041 - 5V

    The board looks like brand new, however, in DIODE mode on PPBUSG3H is 0 and seems in short. I pulled R5400 to make sure the PPBUS was the issue, and pin 2-3-4 give me the right measurements in diode mode, but not PPBUS_G3H. Any hint?
