1. General LCD Screen Guide

Which part do I need?

For most devices there are two options for screen replacement:
  • full LCD screen assembly with everything: glass, touch and display
  • outer glass screen only (includes the front glass and sometimes the touch digitizer)

    a) LCD Display

    An LCD screen is the display under the glass screen that is the source of the image displayed on your phone. For most devices, you can purchase an LCD screen assembly which includes everything: the outer glass, touch digitizer and LCD.

    Replace if:

    • Screen does not come on
    • Black spots on the screen
    • Colors are distorted or washed out
    • Image flickers or wavers
    • Front glass is shattered
    We recommend to purchase the LCD assembly if you are not sure which screen is broken - that way, you have replaced both screens at one time, and you know they are both working correctly. Another reason to purchase the LCD screen replacement is to make sure you don't damage your other screen (either LCD or glass touch) during repair.

    b) Screen Digitizers

    In most devices the digitizer is fused to the glass screen. The digitizer detects your touch. Screens with the digitizer fused together will have a flex cable attached to the screen.

    Replace if:

    • Screen won't respond to your touch
    • You cannot select any icons
    • There is a long delay from selecting an app to opening

    c) Glass Screens

    The glass screen is the front glass lens that covers the LCD. Devices with the digitizer and LCD fused together have a glass only screen adhered on top.

    Replace if:

    • Glass is cracked or chipped but all other components above are functioning properly
    • Glass is NOT shattered

    2. General Troubleshooting Guide for iPhone and LCD Screen Replacement

    Anyone can encounter a hiccup with a screen repair. Don't let it stop you; you're on the goal line. Below are some simple steps that might come in handy.

    General Troubleshooting Steps:

    • Confirm you have the right part for your device. Many parts are very similar, but parts are specific to a device and models. A handy tip is to compare the new part to your original part to see if they are the same.
    • Check all cables and connections to make sure they are securely connected and no pins are bent. These are fragile so be careful and do not bend or pull.
    • Clean the connectors like the digitizer flex cable and carefully attempt to reattach the cables. Dirt and dust can disrupt the contacts. For cleaning, it is recommended to use 95% or higher alchol. If available, you can use pressurized air to blow out dust direct.
    • Do a soft reset after reconnecting any cables.

    The glass screen is the front glass lens that covers the LCD. Devices with the digitizer and LCD fused together have a glass only screen adhered on top.

    3. iPhone Home Button Troubleshooting

     *IMPORTANT: Only the original iPhone's home button is capable of using Touch Id function. Installing a new home button (included with some LCD screens) will restore all standard functions, but NOT Touch Id fingerprint features. To get Touch Id, you will need to transfer home button from your original screen.

    Home Button Tips:

    Here are troubleshooting tips for iPhone Home Button not working after screen is replaced.

    1. Reset The Phone

    Doing a full restore on the phone’s software can sometimes help. Back up your phone, reboot your phone into DFU mode and perform a complete restore. In a lot of cases, this will fix your home button wonderfully without any hardware work.


    2. Check The Cables

    The home button and 3D touch share a single cable that leads to your phone’s internals. Problem can also be caused by the home button’s extension flex cable running through the back of the lcd, and/or a damaged camera/speaker flex cable on top. So make sure to check all those cables out carefully. These cables are incredibly fragile. To check it, you’ll have to remove the metal plate that’s behind your screen. If there’s damage to this cable, you’ll have to replace your entire backlight.


    3. Check the Screw

    The screw behind the home button is shorter than the other screws. Make sure you have the right screw. Loosen the screw behind the center of the home button (holding it to the metal bracket).


    4. Disconnect the battery

    With old screen/connections attached, disconnect the battery then reconnect your new LCD and home button circuits before connecting the battery again. Battery must be disconnected before repair starts and ANY connectors removed.


    5. Check Home Button with Original Screen

    Change things around with your phone and see what happens. Does the old home button still work with the old screen?


    6. Turn On Assistive Touch

    While it’s not necessarily an ideal solution, you can turn on a software home button rather than rely on the physical one that failed. When you turn on Assistive Touch, your phone’s operating system will put a virtual home button at the bottom of your screen. It’ll give off a little buzz when you touch it to simulate the feeling of your physical button.

    To turn on this feature, use one of these methods:

    1. Tell Siri: “Turn on Assistive Touch”
    2. Go to Settings -> General -> Accessibility -> Assistive Touch. Turn it on.

    This will work for any situation where you find your iPhone home button not working.
