3.2. Disassembly Steps

1. പവർ ഓഫ്: Completely power off your TCL 50 XL T702W phone.
2. Heat the Back Cover: Apply gentle heat to the edges of the phone's back cover using a hair dryer or heat gun. This softens the adhesive.
3. പിൻ കവർ നീക്കം ചെയ്യുക: Carefully use a thin prying tool or a razor blade to create a gap between the back cover and the phone frame. Slowly work your way around the edges, applying more heat and a small amount of rubbing alcohol if needed, to loosen the adhesive.
4. ബാറ്ററി വിച്ഛേദിക്കുക: Once the back cover is removed, locate the battery. It is often held in place with adhesive tape. Carefully cut the tape with a razor blade and gently pry the battery out. Disconnect the battery connector from the motherboard.
5. Remove Internal Screws: There are typically upper and lower black covers on the back of the phone that secure internal components. Remove all screws holding these covers in place. Use a small magnet to keep track of the screws.
6. Disconnect Side Button Flex Cable: Be aware of the flex cable connected to the side buttons (power/volume). This can be delicate and requires careful disconnection.
7. പഴയ സ്ക്രീൻ നീക്കം ചെയ്യുക: Apply heat to the edges of the front screen. Use a suction cup to lift the screen slightly, then insert a prying tool or razor blade into the gap. Work slowly around the perimeter, applying heat and rubbing alcohol to soften the adhesive, until the old screen can be removed.

If the lower connector is difficult to seat, you may need to carefully trim any rubber surrounding the slot.
2. പശ പ്രയോഗിക്കുക: If the screen functions correctly, power off the phone and disconnect the new screen. Apply the provided adhesive evenly around the frame where the screen will sit.
3. പുതിയ സ്ക്രീൻ ഇൻസ്റ്റാൾ ചെയ്യുക: Carefully align the new screen and press it firmly into place.
4. ഘടകങ്ങൾ വീണ്ടും ബന്ധിപ്പിക്കുക: Reconnect the battery and its connector. Reinstall the upper and lower black covers, securing them with all the screws.
