              LCD Screen Assembly

Once you have removed the back cover, battery, daughterboard, motherboard, and speakers, the LCD assembly will remain.
Depending on your replacement, you may need to separate the housing frame from the LCD/digitizer.
To remove the LCD/digitizer, carefully heat the edge with a heat gun and use a thin blade to separate from the adhesive. Go slowly, and heat often, as the glass cracks very easily. Work around all of the edges and carefully pull the LCD/digitizer from the housing.
Some replacements do not include the foil switch assembly (top right in photo). If this is the case you will have to pry it gently off the old LCD assembly frame. On the new assembly watch the shape and the plastic guide pin. Alignment is important for the switches to work, once reassembled.
