This is straight forward and should be easily accomplished. The toughest part on this repair is to remove the front case. It does bind a bit around the USB port, but will free with a bit of shimming.
remove the batteries, the memory card as well as the carrying strip (if so equipped).
Remove the 2 screws on the right hand side.
Remove the 2 screws on the left hand side.
One more screw on the bottom, underneath the manufacturer's label.
Start spitting the case from the battery compartment. You can use a plastic opening tool, or your finger nails. It does bind a bit at the USB port side, but will separate pretty quick.
With the back removed, the large LCD becomes immediately visible. There are no fasteners, it just rests inside the tray.
Lift the LCD out of the tray and move it to the right of the tray. The cable is still attached to the logic board via a latch.
With the plastic opening tool, or your fingernails, gently flip the latch to the left side. This will free the LCD cable. Remove the LCD and install your new one.
