OnePlus 7T OLED LCD Combo Replacement Guide"

If you're looking for a step-by-step guide to replacing the OLED LCD combo on a OnePlus 7T, this general process will help. It’s advisable to visit a service center like Shahnawaz Mobile Service Centre in Asansol if you're not confident with these steps. Here’s a detailed breakdown for doing it yourself:

Tools and Materials Needed:

Replacement OLED combo (Display + Digitizer)

Precision screwdriver set

Plastic opening tools

Suction cup

Heat gun or hair dryer

Pry tool or thin plastic card

Tweezers

Adhesive strips or glue (B7000 or similar)

SIM ejector tool

Antistatic mat or gloves (optional)


Step-by-Step Guide:

1. Power off the Device

Make sure the phone is turned off to prevent short-circuiting.


2. Remove SIM Tray

Use the SIM ejector tool to remove the SIM tray.


3. Heat the Back Panel

Using a heat gun or hair dryer, gently heat the edges of the back panel. This softens the adhesive, making it easier to remove. Heat for about 1-2 minutes, focusing on the edges.


4. Remove the Back Panel

Use a suction cup on the back glass and a plastic opening tool to gently pry open the back cover. Start at the bottom and slowly work your way around the edges. Be cautious of the fingerprint sensor cable that may be attached to the back panel.


5. Disconnect the Battery

Once the back panel is removed, locate the battery connector. Use a plastic tool to disconnect the battery. This is essential to avoid damaging internal components during the repair.


6. Remove the Midframe

Unscrew all the screws securing the midframe (the protective frame covering the internal components). Once all screws are removed, gently pry off the midframe to access the motherboard and internal components.


7. Disconnect the Display Cable

Locate the display’s flex cable on the motherboard. Use a plastic tool to carefully disconnect it from the motherboard.


8. Heat the Front Screen (for adhesive removal)

Now, heat the front of the phone (the screen) using the heat gun/hair dryer to soften the adhesive holding the OLED display to the frame.


9. Remove the Old Display

Use a plastic card or pry tool to carefully insert between the frame and the display. Slide the card around the edges to separate the old display from the frame. Be gentle, and take your time to avoid damaging the frame.


10. Clean the Frame

After removing the old display, clean any remaining adhesive from the frame using isopropyl alcohol and a soft cloth. Ensure the surface is smooth and ready for the new display.


11. Install the New OLED Display

Take the new OLED combo display and align it with the frame. Feed the flex cable through the correct hole and position the display in place. Make sure the display sits flush with the frame.


12. Reconnect the Display Cable

Once the new display is in place, reconnect the flex cable to the motherboard.


13. Test the New Display

Before sealing everything, reconnect the battery and power on the device. Test the new display for touch response, brightness, and functionality.


14. Reassemble the Device

Once you're satisfied with the new display, turn off the phone again and reconnect all components, including the battery and midframe.

Reattach the back cover by applying new adhesive or glue around the edges. Secure it by pressing gently for a few minutes or using clamps.


15. Final Check

Power on the phone and perform a final test. Ensure everything is working correctly, including the screen, touch, and fingerprint sensor.
