INTRODUCTION

Cracked or faulty display? Replacing the glass is somewhat involved but very doable.

TOOLS:Metal Spudger (1)Phillips #00 Screwdriver (1)Suction Handle (1)Spudger (1)

PARTS:iPhone 3GS Display (1)iPhone 3G 3GS Screw Set (1)iPhone 3G and 3GS Screen Protector (1)




Step 1 — Broken Glass

If your display glass is cracked, keep further breakage contained and prevent bodily harm duringyour repair by taping the glass.

Lay overlapping strips of clear packing tape over the iPhone's display until the whole face iscovered.

This will keep glass shards contained and provide structural integrity when prying and lifting thedisplay.

Wear safety glasses to protect your eyes from any glass shaken free during the repair.

Step 2 — Display

Remove the two Phillips #00 screwsfrom the dock-connector end of theiPhone.

Make sure to keep all the screwsorganized as you are taking thephone apart. They are differentsizes.




Step 3

Remove the metal handle from thesuction cup. It's easier and safer togrip the suction cup's base insteadof the metal handle.

Be very careful when opening theiPhone so that the cables under thedisplay are not severed.

There is a rubber gasket betweenthe silver front bezel and blackdisplay assembly. A bit of force isrequired in this step to separate theiPhone's display assembly.

Use a small suction cup near theHome button to gently pull up thelower portion of the iPhone's displayassembly.

If the display assembly is toodamaged to allow the suction cup toadhere, tape with a strong adhesivesuch as duct tape may be used.




Step 4

The display assembly is stillconnected to the iPhone by severalcables, so don't try to remove itentirely just yet.

Rotate the display assembly up untilit is at an angle of approximately 45degrees.




Step 5

Continue to hold the displayassembly with one hand, and useyour other hand and a spudger todisconnect the black ribbon cablelabeled "1."

Ribbon cable "1" is connected with aplug style connector. The block atthe end of the cable is the plugwhich is simply pushed into a socketon the circuit board. No other lockingmechanism is used.

Step 6

Rotate the display assembly up untilit is roughly vertical. This will alloweasier access for disconnecting theremaining cables.

Use a spudger to disconnect theblack ribbon cable labeled "2."




Step 7

Ribbon cable "3" is held in place by a FPC style connector. You must unlock this connector beforesliding the ribbon cable out. The locking mechanism is on the opposite side of where the cable isinserted - it swivels upwards 90 degrees. Use a plastic spudger to lift the locking mechanism.

The FPC locking latch is very delicate and is typically a different color than the body of theconnector. (see the detail image of FPC connector open and closed)

Slide the ribbon cable out of the connector, and remove the display assembly from the iPhone.

It's impossible to properly reinsert a ribbon into an FPC connector unless the lock is disengaged.Make sure the locking latch is open when attaching/detaching the cable.




Step 8

Remove the single Phillips #00screw from the corner of the displayassembly.

Step 9

Remove the two Phillips #00 screwsfrom the right side of the displayassembly.




Step 10

Turn the display around, and if thereis a thin strip of black tape on theedge of the display assembly,carefully peel it up.

Keeping the tape from sticking toitself can be tricky. We recommendplacing the tape on a wax-coatedpiece of paper (any sticker backingwill do).

Step 11

Remove the three Phillips #00screws from the left side of thedisplay assembly.




To reassemble your device, follow these instructions in reverse order.

Step 12

Turn the display assembly over andagain carefully insert a metalspudger between the two metal railsalong the edge of the displayassembly. Gently rotate the spudgerto lift the LCD up from the glass.

Step 13

Separate the LCD and glass bysliding the LCD panel away from theribbon cables on the glass.
