If you need to do some repairs or something in there. You need a Vise Grip/Locking pliers, a hammer and something to protect the top cap from the jaws, I used a piece of leather. Wrap the top cap in the leather, position the locking pliers and tighten it down. Hold the whole shebang an inch or two from your work surface and whack the hammer on the pliers. A few good hits should to it, you may need to reposition the locking pliers. Takes a minute or two, tops. Careful if you're not replacing the PCB, the wires are pretty short and you don't want to rip them out.
My son needs to replace his PCB as well, we're hoping to get a video of him doing it. Once the top cap is off it's a cakewalk.
