When your Samsung mobile phone breaks, you may be tempted to throw it away or buy a new phone. Replacing broken parts on your mobile costs just a fraction of the price it costs to replace your damaged phone. You can purchase nearly every replacement part for your Samsung mobile phone online. Everything from a replacement LCD screen to a keypad can be found on such cell phone repair websites as Cellulardr.com or Puremobile.com.
Replacing the LCD screen and keypad
Power down your mobile phone, and then place your phone face down. Remove the battery cover, and remove the battery from its compartment. Set the battery aside.
Remove the Phillips-head screws from the back cover. Some Samsung phones have two screws on the bottom or top two corners. They also may have a Phillips-head screw on each corner of the rear casing.
Insert a guitar pick or credit card into the crease along the outside edge of the phone. Work your way all the way around the phone until the back casing is separated from the phone and the circuit board is visible.
Disconnect the LCD screen ribbon cable from the bottom-right corner of the circuit board. Remove the Phillips-head screws that attach the top corners of the circuit board to the phone.
Tilt the circuit board downwards until you see the ribbon cable located on the bottom left-hand or right-hand corner of the corner on the opposite side of the circuit board. Disconnect the keypad ribbon cable and remove the circuit board from the phone.
Separate the plastic bezel from the front of the LCD screen, and remove the keypad from the phone. Use a guitar pick or credit card to separate the LCD screen from its compartment.
Install the new LCD screen and keypad by repeating this procedure in reverse.
Your replacement LCD and keypad assemblies will come with replacement ribbon cables. Connect the replacement ribbon cables to the appropriate connectors on the circuit board.
