Important Safety Information and Precautions

• The screen is fragile. Handle with utmost care during replacement to prevent damage to the LCD and IC chip.
• We highly recommend seeking professional expertise for installation if you are not confident in your abilities.
• Before installing the new screen, ensure the device battery is disconnected.
• After installation, connect the new screen and reboot the device for a final functionality test.
• Note that after replacing the screen, certain functions (e.g., fingerprint sensor if integrated into the original screen) may no longer be available. Please consider this before purchase and installation.

Pre-Installation Testing

Before fully installing the screen, it is crucial to perform a test to ensure it is fully functional. This step helps identify any potential defects before permanent installation.

1. Carefully unpackage the new screen.
2. Connect the flex cable of the new screen to the motherboard connector of your device. Do not apply adhesive or fully assemble yet.
3. Reconnect the battery.
4. Power on the device.
5. Test all functions: check display quality, touch responsiveness across the entire screen, color accuracy, and ensure there are no dead pixels or lines.
6. If any issues are detected, disconnect the battery and contact customer support immediately. Do not proceed with full installation.
7. If the test is successful, power off the device and disconnect the battery before proceeding to installation.

Installation Instructions

Follow these steps carefully for a successful screen replacement. Refer to the included tool kit and online instructional videos if needed.

1. Power Off Device: Ensure your Tecno Spark Go 2023 BF7n 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 the Edges (Optional but Recommended): Gently heat the edges of the old screen with a heat gun or hairdryer to soften the adhesive. This makes removal easier.
4. Pry Open: Use the suction cup to create a gap between the screen and the frame. Insert a thin pry tool (plastic spudger) into the gap and carefully work your way around the edges to separate the old screen.
5. Disconnect Flex Cables: Once the old screen is partially lifted, carefully disconnect the flex cables connecting it to the motherboard.
6. Clean Frame: Remove any remaining adhesive or glass fragments from the device frame. Ensure the surface is clean and smooth for the new screen.
7. Connect New Screen: Carefully connect the flex cables of the new SRJTEK screen to the corresponding connectors on the motherboard. Ensure they are securely seated.
8. Test Again: Before applying adhesive, perform another quick functionality test as described in the "Pre-Installation Testing" section.
9. Apply Adhesive: If the test is successful, apply new adhesive (not included, but often part of repair kits or purchased separately) around the frame where the screen will sit.
10. Secure New Screen: Carefully align and press the new screen into place. Ensure it sits flush with the frame.
11. Reassemble: Reconnect the battery, reinsert the SIM tray, and power on your device.

Maintenance and Care

To ensure the longevity and optimal performance of your new screen, follow these maintenance guidelines:

• Avoid dropping your device, as impact can damage the new screen.
• Clean the screen with a soft, lint-free cloth. Do not use harsh chemicals, abrasive materials, or excessive pressure.
• Consider using a screen protector and a protective case for added durability and scratch resistance.

Troubleshooting

If you encounter issues after installation, refer to the following common problems and solutions:

• Screen Not Turning On: Ensure all flex cables are securely connected to the motherboard and the battery is properly reconnected. Try a hard reset of the device.
• Touch Not Responding: Check the touch screen flex cable connection. Ensure there are no debris or damage to the connector.
• Display Issues (Lines, Dead Pixels, Incorrect Colors): This may indicate a faulty screen or a damaged flex cable. Recheck connections. If the issue persists after re-seating connections, contact customer support for a replacement.
• Screen Flickering: Verify all connections are firm. If the issue continues, it might be a screen defect.
