No display - Black plastic clamp on the motherboard that holds the video cable down broke while I was trying to replace the battery. Unfortunately the part can't be easily replaced, so I had to get the whole motherboard. IFIXIT had the right part and the best price.
It was quick, swapped the motherboard out in 15 minutes. It would have been 10 if I had tiny hands. :)
Go slow, it's easy to break connectors. Take pictures to see how things go back together. Ensure the battery is disconnected first. This fix was pretty easy though.
