Введение

Replace your phone's cracked screen or unresponsive LCD display to give it a fresh appearance. The screen and LCD display are glued on and wired in place, so replacing this part requires patience. Because the screen and LCD display are one piece, replacing one means you are placing both.

  1. Pull and twist the pin near the bottom left-side of the phone to remove it from the headphone jack.

    • Remove the two 2mm Phillips #000 screws securing the copper flex cable to the silver metal tab.

    • The screw on the left has white paint on the top. Chipping the paint will void any warranty you have for your phone.

    In my new Back Battery cover case there is no possibility to screwing the silver metal tab with these 2 screws to securing the copper flex cable . I only can put the silver metal tab with adhesives (double side tape)

    • Wedge the flat end of a spudger underneath the bottom left of the metal tab.

    • Run the spudger along the bottom edge of the metal tab and gently pry upward.

    • Adhesive under the metal tab will make lifting the tab slightly tedious. The adhesive will come off as long as you gently run the spudger along the bottom of the tab.

    • Use an iSesamo tool to separate the gold wire from the silver metal plate.

    • This piece will not come off completely, but it must be separated in order to remove the display.

    • Be careful not to slice or damage the wire. The wire is attached to the panel with a layer of adhesive, so it will take some effort to remove.

    • Use a heat gun to loosen the adhesive between the display and frame.

      • Start with the heat gun far away from your hand. Then, slowly move your hand towards the heat gun until the air is warm, but not hot.

      • At this set distance, slowly warm the entire front of the phone.

    • The heat gun can be dangerous to you and to the phone. Avoid placing your hand too close to the end of the gun, as it can burn you. Also avoid heating the bottom plastic panel of the phone because it can melt when exposed to direct heat.

    • Use the iSeasmo tool to wedge between the screen and the plastic near the bottom right corner of the phone. You must wedge the iSeasmo underneath the white plastic part of the screen, and not just the glass.

    • Run your iSeasmo tool slowly to the left and right to begin separating the display.

    • Run your iSeasmo tool along the right and left edges of the display.

    • Adhesive will be found throughout this process, so you must be patient with the separation. Check the back of the phone once in awhile to make sure you are not cutting any wires.

    • Once the display is loose enough, gently begin separating it from the bottom of the phone. Work your way up until it is completely removed.

    • Some wires will need to be fed through holes in the plastic before the display can be fully removed.

    • Avoid forcing the screen from the plastic. This can damage the screen along with the internal wiring. Take this step very slowly, and go back to remove any extra adhesive if necessary.
