Okay, not that experienced with the 13in unibody but I’ll give it a shot. # Try the usual PRAM and SMC reset, I’d especially try resetting the SMC # Maybe the display connector has gotten loose? It’s highly unlikely but it doesn’t hurt to check # Try booting with the “no battery installed” option. Since you’ve opened up the laptop, you should be able to just disconnect the battery, but try doing the following with the battery first. ** Unplug everything ** Hold the power button for at least 10 seconds, don’t release ** Keep holding the power button, plug in the charger, then hold the power button for another 10 seconds ** Release the power button, then press the power again like you normally would boot # I’ve had to do this for macs without a battery, I think it will also ramp the fans up to 100%, but see if there is a screen.
