In answer to the original question of removal I took mine out last week and it was really simple.
There are 2 screws either side of the mounting bracket which can simple be undone with a stubby philips.
There are the 3 (red, yellow, white) wires at the back. Mine had been sealed in thin foam which you just need to cut or tear in order to disconnect the wires.
Then it was a simple case of pullung out the power cable.
It went back in just as easily.
