I just replaced mine. Just make sure to check the version number on the board before ordering the replacement. Mine was Rev 1.4. If you get one with a different rev your screen will not work. Unfortunately the rev number is on the back of the board so you’ll have to remove it first.
The first larger ziff connector the black part flips up and forward towards the top of the tablet. The two smaller ones the white part flip up and back towards the bottom of the unit.
I found that I did not have to remove the battery first. There’s small bit of metal near the edge of the board. Once the screws are out of the board it will slide down enough to let you slip it from under the metal.
