LCD / Digitizer Screen Installation

Test the LCD / Digitizer Screen BEFORE installing in device

Steps to follow:
  • Do not remove protective screen film/ cover
  • Attach the flex cable from the new LCD or digitizer screen to your phone or tablet.
  • Ensure the flex cables are seated correctly with a "clicking sound". Start at one end of the connector and use a gentle rocking motion while you work your way to the other end. (IMPORTANT: DO NOT BEND - CABLE IS VERY FRAGILE)
  • WARNING - Do not press the left and upper corners of the screen, otherwise it may cause lines on the screen.
  • Attach original home button and power on your phone or tablet
  • Test if the image and touch screen (all letters) are working. (Make sure your phone is charged)
  • If failure - clean connectors with 99% alcohol and repeat steps described above.

Damaged or defective items must be reported within 72 hours of receipt of order. Once installation begins, removing the screen's protective film and/or applying adhesive will void returns, refunds, and exchanges.

Screen Replacement Preparation

  • Watch a repair video on YouTube before starting the repair. Repair Videos »

  • Review tools in Repair Tool Kit - here.

  • Back up your devide via iCloud or iTunes before proceeding
  • Keep track of screws.
    Many screws will be removed and then re-installed when replacing the screen. These screws are of different size and length. Mark each screw in order that you remove and related assembly with a number so that you can recognize them easily. If you put a screw into the wrong place, your phone could be damaged.

  • Keep all pieces organized and numbered and work on a well lit WHITE paper base (like a napkin or paper towel) so that you can see any little pieces that might go missing.

  • Confirm the phone is powered off before starting the repair.

  • Cover the screen with packing tape to avoid injuries and to help the suction cup stick

  • WARNING - Don’t force the connectors together until they are properly lined up.

Treat Flex Cables Gently

  • Use tools instead of your finger during the installation. Otherwise, it will damage the screen!

  • Check for any dust or debris in between the flex cables and motherboard. Clear it with a brush or an alcohol dipped cloth.

  • Make sure the flex cables are properly connected with a “clicking” sound.

  • Don't bend the flex cables.

Static Free Environment

  • To prevent equipment damage, make sure you start your repair in a static-free environment. Use latex gloves or rubber mat, one designed for anti-static or just a household table place mat. You can avoid electro-static by using proper grounding techniques such as wearing an anti-static bracelet.

  • In particular, after failing to install an LCD assembly the first time, when you try to install it by connecting the connector to the motherboard the second time static will be generated and it will damage the IC on the flex cable or connector rendering the assembly defective.

Protective Film

  • Most screens come with a protective film to guard against scratches. DON'T remove this until the new part is secured in the phone. The glass screen attracts dust and fingerprints and the protective film will help reduce this.
  • Make sure to remove the red/purple static protection sheet from the metal on the back of the LCD (using small tab sticking out).

    Glass Screen Installation

    RepairPartsPlus has done extensive research to identify the best adhesive to secure your glass or lcd to your phone. 2mm double-sided adhesive is easiest to use and specially designed to fit the phone edges. Adhesive is necessary if replacing the front glass or digitizer only. It is optional for LCD screen assemblies. Adhesive is not required, if the frame is being replaced such as with an iPhone LCD screen.

    Apply the adhesive strips all along the edge of the screen and then in the middle of any solid back areas at the top and bottom. Just peel the adhesive strips and cut as needed.

    Here is a link to a YouTube video showing how to use double-sided adhesive:

    Note: Replacement screens can be secured using adhesive tape strips or UV glue. While the UV glue provides a stronger, longer lasting bond, the adhesive strips are a much safer solution. Use of UV glue requires a curing lamp and can result in damage to a device if too much is used and it seeps into other parts of the phone. We don't recommend glue for first time DIYers. UV glue and a curing lamp can be purchased separately if desired.

    Good luck with your repair!
