basically heres how i did it. I will not be held responsible if you flowers your mpc up trying this. But hey, some people consider this a tough job, for professionals only.
step 1- remove static from your body and take good screen from unplugged broken mpc (refer to step 2 for info on removing cover). I had to unscrew the top circuit board (the one with the pad sensors) to slide it back to get access to the screens connections. the top circuit board is held in place with 5 screws, 2 on each side, and one on top under the cursor buttons. Once its slid back, you can remove the 2 tiny screws holding the screen (and its circuit board) in place. Once those are out, pull it up a little so you can get to the connections. theres 2 connections, the small white one with 2 wires on it, that comes off with pressure on either side of the connection, then just pull it out. the other connection is a longer black one, with a ribbon wire hooked up to it. pull up on the outter rim of the connection to release the pressure on the ribbon. Once its free, you can pull it out, and theres your screen.
step 2- take cover off good mpc- unplug unit and discharge static from your body. pop off your note variation slider knob thingy, then remove the 2 big screws on both sides, 3 screws on the back. Remove the 3 screws on the under the front cap, then the cap will slide out straight to you. Once thats off, theres 3 more screws in the front holding the main part of the cover down, remove those then gently take off the cover. Now is a good time to clean the dust out of the inside of your machine, or maybe even customize the paint on the cover.
step 3- slide the top circuit board back (5 screws) and remove the defective screen the same way as i removed the good screen in step 1. Now install the good screen the same way you took it out, and make sure your ribbon is going in the right way, and your connections are tight. Next, rescrew the top circuit board and put the cover back on in reverse of how you took it off.
step 4- plug in mpc and look at your new screen.
