3. Important Pre-Installation Warnings

Please read these warnings carefully before proceeding with installation. Failure to follow these instructions may result in damage to the product or your device, and may void any potential claims.

• Professional Installation Recommended: If you are not professional with phone repair, we strongly recommend seeking technical assistance from a qualified repair store. LCD screens are fragile and can be easily damaged during installation.
• Pre-Installation Testing is Crucial: ALWAYS test the display thoroughly before final installation. Connect the new LCD assembly to the motherboard without fully installing it, and check for display issues, touch responsiveness, and brightness adjustment.
• Video Recording: It is highly recommended to record a video when you unpack the package and during the pre-installation testing process. This video will serve as valid evidence in case you receive a damaged product or encounter issues before full installation.
• Warranty After Installation: Please be aware that the merchandise is typically without warranty after installation. Any damage incurred during or after installation will generally not be covered.
• Screw Caution (for "LCD With Frame" option): If you choose the "LCD With Frame" option, ensure that screws are installed only on the motherboard cover and NOT directly on the motherboard. Incorrect screw placement can damage the screen or motherboard.

4. Installation Guide

This section outlines the general steps for replacing your OPPO Realme 9 Pro LCD display. Please note that this is a general guide, and specific disassembly/assembly steps for your phone model may vary. Refer to device-specific repair guides or seek professional help if unsure.

4.1. Choosing Your LCD Type: "No Frame" vs. "With Frame"

The LCD display is available in two configurations:

• LCD No Frame: This option includes only the LCD and digitizer assembly. It requires transferring the original frame from your phone to the new display. This process is more complex and carries a higher risk of damage if you are not experienced. Professional installation is highly recommended for this option.
• LCD With Frame: This option includes the LCD, digitizer, and a pre-attached frame. This simplifies the installation process as you only need to transfer internal components (motherboard, battery, etc.) to the new frame. The risk of damage is relatively lower, making it suitable for DIY repairs with proper care.

4.2. General Installation Steps (Summary)

1. Power Off Device: Ensure your OPPO Realme 9 Pro is completely powered off before starting.
2. Remove Back Cover: Carefully heat and pry open the back cover.
3. Disconnect Battery: Disconnect the battery flex cable to prevent short circuits.
4. Remove Old Display:
   • For "LCD No Frame": Carefully heat the edges of the old display and pry it off the frame. Clean any old adhesive from the frame.
   • For "LCD With Frame": Disassemble all internal components (motherboard, battery, cameras, etc.) from the old frame.
5. Pre-Installation Test: Connect the new LCD display's flex cables to the motherboard. Power on the phone and test all display and touch functions (refer to Video 1). If any issues arise, do NOT proceed with full installation and contact support.
6. Install New Display:
   • For "LCD No Frame": Apply new adhesive to the phone's frame. Carefully align and press the new LCD assembly onto the frame.
   • For "LCD With Frame": Transfer all internal components from the old frame to the new frame. Ensure all flex cables are properly connected.
7. Secure Components: Reconnect the battery, reassemble any removed components, and secure them with screws. Remember the warning about screw placement for "LCD With Frame" option.
8. Reattach Back Cover: Apply new adhesive if necessary and carefully reattach the back cover.
9. Final Test: Power on your device and perform a final check of all functions.

5. Operating the Display

Once installed, your new LCD display will function identically to the original. It supports:

• Touch Functionality: The capacitive touch screen provides responsive and accurate touch input.
• Brightness Adjustment: The display supports brightness adjustment through your phone's settings.
• Color Reproduction: The IPS LCD panel is designed to present colors accurately.

Perform a full test of all screen areas and touch gestures after installation to ensure proper operation.

6. Maintenance and Care

To ensure the longevity and optimal performance of your new display, follow these maintenance tips:

• Cleaning: Use a soft, lint-free cloth, preferably microfiber, to clean the screen. For stubborn smudges, lightly dampen the cloth with water or a screen-specific cleaning solution. Avoid harsh chemicals or abrasive materials.
• Oleophobic Coating: The screen features an oleophobic coating to resist fingerprints and smudges. Avoid using harsh cleaners that can degrade this coating over time.
• Screen Protector: Apply the included tempered film or another high-quality screen protector to add an extra layer of protection against scratches and minor impacts.
• Avoid Pressure: Do not apply excessive pressure to the screen, as this can damage the LCD panel.
• Temperature Extremes: Avoid exposing your device to extreme temperatures, which can affect screen performance and lifespan.

7. Troubleshooting

If you encounter issues after installation, consider the following common troubleshooting steps:

• No Display / Black Screen:
  • Ensure all flex cables (display and touch) are securely connected to the motherboard.
  • Check for any visible damage to the flex cables or connectors.
  • Try restarting the phone.
• Unresponsive Touch:
  • Verify the touch digitizer flex cable is properly connected.
  • Ensure there is no debris or adhesive interfering with the touch sensor.
  • Perform a hard reset of the device.
• Display Anomalies (Lines, Spots, Discoloration):
  • This often indicates physical damage to the LCD panel, possibly during installation.
  • Recheck flex cable connections.
  • If the issue was present during pre-installation testing, do not proceed with full installation.
• Screen "Exploded" or Damaged During Assembly (for "LCD With Frame"):
  • This can occur if screws are tightened directly onto the motherboard instead of the motherboard cover. Always ensure screws are placed correctly to avoid damaging the screen or internal components.

If troubleshooting steps do not resolve the issue, it is recommended to seek professional repair assistance.

9. Warranty and Support

Please note the following regarding warranty and support for this product:

• No Warranty After Installation: This product typically does not carry a warranty once it has been fully installed into the device. This is due to the delicate nature of LCD components and the potential for damage during the installation process.
• Pre-Installation Claims: Any claims for defects or damage must be made before the product is fully installed. Ensure you thoroughly test the screen upon receipt and before final assembly. Remember to record an unboxing and pre-installation testing video as proof.
• Technical Assistance: If you are unsure about any step of the installation process, or if you encounter issues that cannot be resolved with basic troubleshooting, it is strongly advised to seek professional technical assistance from a certified phone repair technician.

10. User Tips

Based on common experiences and best practices, here are some additional tips for a successful replacement:

• Patience is Key: Phone repair requires patience. Do not rush any steps, especially when prying components or connecting flex cables.
• Organize Screws: Keep track of all screws and their original locations. Using a magnetic mat or labeled compartments can be very helpful.
• Heat Carefully: When heating adhesive, use a heat gun or hairdryer on a low setting and move it constantly to avoid overheating any single area.
• Use Proper Tools: Utilize the correct tools for prying, unscrewing, and disconnecting. The included free tools are a good starting point, but specialized tools may offer better results.
• Static Discharge: Before handling internal components, discharge any static electricity from your body by touching a grounded metal object.
