Now the back can be lifted. Be careful with the delicate ribbon cables. I have chosen to keep the back connected and to work extra carefully not to put excessive strain on the ribbon cables. You might want to disconnect them by lifting the tab of the smaller ribbon, and pulling out the black part of the larger cable.

BE CAREFUL! the left side of the device contains a capacitor that can hold a charge for quite a while, and deliver a nasty shock. DO NOT TOUCH!
