Text box telling us to be sure to disconnect the battery blocked the actual battery cable removal. Detail good on removal of logic board but never addressed the DVD drive, the battery, or the hard drive.
Why did it not turn on again after assembly? What happened that the screen is blank after you press the power to turn it on? I followed your steps and here I am now, with no power, no fan and nothing at all turning on.
