Probably, many owners of touchscreen phones are familiar with the problem of loss of screen sensitivity. If it is expensive for you to send the device for repair to the service department, there are several ways to fix the sensor without the help of specialists.
It is necessary
- - small Phillips screwdriver;
- - hex screwdriver;
- - stationery eraser;
- - scotch tape.
Instructions
Step 1
Clear your work area of unnecessary items. Use a small box to store the bolts so they don't get lost. Separate the sides from the phone. Using a hex screwdriver, unscrew the two bolts at the bottom of the rear cover and the two bolts under the sidewalls. Also remember to remove the two screws in the battery compartment. Where the sidewalls were removed, you will see the latches. Use a screwdriver to pry off the top cover. Turn off the shield connector and use a Phillips screwdriver to unscrew the two screws located at the top. Locate the headphone jack in the upper right corner of the board. There is a microphone under it. Release the connector from the phone case and separate the board from the screen.
Step 2
Use an eraser to clean the cable contacts - they should shine. Next, turn the shield over and connect it to the board. Then you need to turn on this design. Attach the battery to the board with adhesive tape. In order for such a design to work, it is necessary to remove the lock, which is located between the battery and the CF-connector. Press the Power button on the board.
Step 3
Failure usually consists of the contact from the ribbon cable to the touch screen that does not pass. To make sure of this, put an eraser on the area where the screen and the cable join. Press lightly on it and move the stylus across the screen. If everything works, it can be easily repaired. Cut a straight and very thin strip of eraser, about 1 mm. Then glue this strip with glue, which does not immediately freeze, to the place of contact of the cable with the screen. If during reassembly it turns out that the screen is not restored, simply move the eraser to a suitable location.
Step 4
Reassemble all parts in reverse order. Don't forget the microphone and the scotch tape left behind to secure the battery. Sometimes it happens that disassembly leads to a hard reset, for example, due to a dead auxiliary battery. In this case, make Russification and start the recovery process.
