She is going through her insurance to get it replaced but might still have it repaired, depending on insurance. Thanks, and ill have another board...

    Ok haha that did not go well, after I replaced the LED Driver, since im a n00b, it ended up burning up the LCD connector for some reason, and now it would need a new screen since replacing that connector is practically impossible, unfortunately I will not be repairing this MacBook! I'll stay on...

    So, the Capacitor I removed was shorted to ground C8359 I2C_BKLT_ICL, when I removed that, the pads were both shorted to ground. So you recommend I remove R7750 which I did, that removed the short, or are you saying that its not a short, but maybe I misunderstand... I replaced R7750 and I...

    Thanks for the help, I actually found that it was shorted at R7750 and then read your comment, :-) I removed it and the short is gone... So I'll need to replace that resistor and the capacitor I removed unecessarily... Ill need to find the part from a donor board.... I need to replace these...

    Just was watching Louis' video on his repair, and he found a short to ground off the bklt_en resistors, well I found one too at C8359 which is the IC2_BKLT_SCL line, I just removed it and the short is still there, so I guess that means I need to check the rest of those Capacitors in the line?? I...
