Here’s an example of the light leak issue with iPhone 3g. (Photo taken by tschur at MacWorld)



Here's how I fixed mine:

1. Remove the two screws on either side of the charging port


2. Apply a suction cup (I used my Garmin windshield mount), to the glass screen. Try to mount it right below the home button.


3. Pull the suction cup toward you and the screen should come out (bottom first)
CAUTION: Very SLOWLY pull your iPhone apart. Cable 4 sometimes sticks to the LCD unit and will snap if you do not unstick it. See page 2 for a picture of where cable 4 is located. (Thanks to netling and bigfishman for pointing this out)


4. You will see 3 cables running from the top right corner of the screen to the main board of the phone. 3 cables are numbered 1, 2, and 3. Remove the cables in that order. (Note: in the picture, my number 1 cable has already been detached, number 3 is underneath number 2)


5. Once the three cables are detached, the entire LCD unit is now separate from the main board. I found two youtube videos that might aid you in the process of removing the screen.

6. Look on the left side of your iPhone LCD unit; you will notice that Apple has already applied a small strip of electrical tape to the metal casing. Unfortunately, this strip is sometimes misaligned, causing light leakage. Simply add more electrical tape to anywhere you experience light leak.


Note: the tape does NOT have to cover the black rubber gasket (the part that meets the bezel when assembled). Simply apply electrical tape to anywhere on the metal frame supporting the LCD unit. Apply tape to all the places you experience light leak.

7. Reassemble the phone, reconnecting cables 1, 2, and 3, and then re-screw the two screws holding the LCD unit in place.

Your phone should now be light leak free!! Enjoy!

**All of the pictures were taken by me, except for the first, and the two youtube links.

Thanks! Rep. for you. Fixed my power button with that tut

Nice man thanks. Anybody know if this would work for uneven screen issues?

Excellent, great idea using the suction cup! I was wondering what damage would be done using a tool to prise out the screen! and the Youtube guides always look easy but suspiciously like they ahve already been opened! Remember how easy PDAparts made opening the 2G until you tried it and bent the case... w@nkers.
Rep for you!

That suction cup is a simple but great idea!
Rep for you!

nice guide, thanks!

Thanks for the guide.

I'm moving it to the Hardware section, BTW
