  5. LG G4 LCD and Digitizer Replacement, Motherboard: 手順 5、 2の画像 1 LG G4 LCD and Digitizer Replacement, Motherboard: 手順 5、 2の画像 2
    • Remove the following four press-fit connectors with the flat edge of a plastic spudger or opening tool:

    • Front-facing camera connector.

    • Rear-facing camera connector.

    • Digitizer connector.

    • The rear-facing camera may be held down to the frame with two sided tape. Try to move the camera with the spudger prior to lifting the motherboard If it does not budge, use the same tool to pry it from the frame to avoid damaging the connector cable in the next step.

    There is a ribbon on the left of the camera. Use spudger to lift this so that the camera is left behind. Do not fiddle with the rear facing camera.

    I second that! Just unsnap the camera connector like the other two. Unsticking the camera instead is silly, when that is so much simpler. Please update this to mark the third connector to be unsnapped.

    I lifted the ribbon but I can't get it to stick back down!

    I tried lifting the ribbon but it didn't unsnap… it actually felt like it ripped off. I couldn't get it to “snap” back down like the other ones.

    • Remove the motherboard by lifting it up using the plastic opening tool and your fingers .

    My LG G4 has stopped working. Was told it needs board replacement. How do I get the motherboard. I reside in Nigeria.

    I realize this is over a year old, but for anyone else’s future reference you can find replacement boards on ebay. There is even a seller with brand new 700’s serial number boards (AKA the last batches available after the bootloop recalls). I think the name is “gsmplaza” IIRC; they’re based in Israel and are the only sellers selling BRAND NEW boards, not refurbished or used, so it shouldn’t be hard to find.

  7. LG G4 LCD and Digitizer Replacement, Screen Assembly: 手順 7、 1の画像 1
    • Use a heat gun or iOpener over the auxiliary port to soften the adhesive that secures it to the plastic housing.

    I found this to be unnecessary. Mine came out easily when I shoved a small screwdriver all the way to the back and gently pulled upwards. Mine may have been loose from lots of use though.

    • Use a spudger to carefully remove these components and then place them in the new display assembly..

    • Use a heavy duty suction cup and firmly pull the screen away from the frame to create a small gap.

Per the LG G4 Teardown guide, the glass, digitizer, and LCD are all fused together, so you have to replace the whole assembly

Lorsqu’on remplace l’ensemble écran + LCD achetés ensemble et que l’on transfère les pièces de l’ancien cadre (caméra, vibreur…), il ne faut pas oublier de transférer également 3 petits caoutchoucs carrés noir ou gris (2 en haut de chaque coté du haut parleur, et 1 en bas à gauche de la prise jack), sinon le détecteur de proximité ne marche pas et l’écran s’éteint et le reste lorsqu’on téléphone…

C'est bien qu'on fasse cette observation. Mon technicien avait omis ces neoprenes et j'ai pu les transférés.

My tech had omitted these pads. I am super grateful someone commented that the phone would black out on a call. Problem solved!
