Package Contents

The package includes the following items:

• 1 x LCD Touch Digitizer Assembly for Nokia 1.4 TA-1322
• 1 x Set of Basic Installation Tools

Note: The provided tool kit is a general set and may not be suitable for all phone models or specific repair steps. Additional specialized tools may be required.

Pre-Installation Checks

1. Verify Product Condition: Upon receipt, inspect the LCD assembly for any physical damage, cracks, or missing components. If any issues are found, do not proceed with installation and contact customer service immediately with photos.
2. Test Functionality: Before full installation, connect the new LCD flex cable to the phone's motherboard without fully installing the screen. Plug in the charging cable and power on the phone to check if the screen functions normally (display, touch response). Do not remove any protective films or labels during this test.
3. Static Electricity Precautions: Wear an ESD (Electrostatic Discharge) wrist strap to ground yourself. This prevents static electricity from damaging sensitive electronic components within the phone.
4. Battery Disconnection: Always disconnect the battery cable connector before disassembling the phone or connecting new components.

Installation Steps

The installation process for a phone screen replacement requires precision and care. This manual provides general guidance. For detailed visual instructions, it is highly recommended to refer to online video tutorials, such as those available on YouTube, specifically for the Nokia 1.4 TA-1322 model.

Warning: Installation requires a certain level of technical skill. If you are not experienced in phone repair, it is strongly recommended to seek professional service to avoid damaging your device or the new screen.

1. Power Off Device: Ensure the phone is completely powered off and the battery is disconnected.
2. Remove SIM Tray: Use the SIM ejector tool to remove the SIM card tray.
3. Heat and Separate: Carefully apply heat to the edges of the old screen to loosen the adhesive. Use a thin prying tool (e.g., plastic spudger or guitar pick) to gently separate the old screen from the phone frame.
4. Disconnect Old Screen: Once the old screen is separated, carefully disconnect its flex cables from the motherboard.
5. Clean Frame: Thoroughly clean any old adhesive residue from the phone frame.
6. Connect New Screen: Carefully connect the flex cables of the new LCD assembly to the corresponding connectors on the motherboard.
7. Test Again: Perform the functionality test as described in the "Pre-Installation Checks" section before fully securing the screen.
8. Secure New Screen: Apply new adhesive (not included, but often recommended) around the frame and carefully place the new screen into position. Apply gentle, even pressure.
9. Reassemble: Reconnect the battery, reinsert the SIM tray, and reassemble any other components.

Important Precautions

• Handle with Care: The LCD is a fragile component. Handle it gently to avoid breakage.
• Avoid Excessive Force: Do not apply excessive force to the screen corners or edges during installation, as this can cause damage.
• Flex Cables: Be extremely careful when connecting and disconnecting flex cables. Do not bend them sharply or apply undue pressure.
• Protective Films: Only remove protective films and labels after successful testing and when you are ready for final installation.

Troubleshooting

If you encounter issues after installation, consider the following:

• No Display/Touch: Recheck all flex cable connections to ensure they are securely seated.
• Screen Flickering/Lines: This could indicate a loose connection or damage to the flex cable. Disconnect and reconnect carefully.
• Unresponsive Touch: Ensure the touch digitizer flex cable is properly connected.
• Static Issues: Verify proper grounding during installation.

If problems persist, take photos or videos of the issue and contact customer support for further assistance. Do not attempt to force installation or repair if you are unsure.
