Probably, many are familiar with the problem of loss of sensitivity of the touch screen on a PDA. In case you thought it was not economical to carry it to a service center for repair and think that you can repair it yourself, then this article will help you.
It is necessary
A small Phillips screwdriver and a hex screwdriver, plus a stationery eraser and tape
Instructions
Step 1
Free your workplace from unnecessary items. Prepare a box to store the bolts so they don't get lost. Separate the sides. Unscrew the two bolts under the sidewalls and the two bolts at the bottom of the back cover with a hexagon. Also unscrew the bolts in the battery compartment. There are latches in the place where you removed the sides. Separate the top cover with a screwdriver. Disconnect the shield connector and use a Phillips screwdriver to unscrew the two screws at the top. The headphone jack is located in the upper right corner of the board. There is a microphone under it. Loosen the connector from the case and separate the board from the shield.
Step 2
Use an eraser to clean the loop contacts - they will start to shine. Flip the screen. Connect the shield to the board. Next, you need to enable this design. Secure the battery to the board with tape. For this design to work, you need to remove the lock, which is located between the CF-connector and the battery. Press the Power button on the board.
Step 3
Usually the breakdown consists in the fact that the contact of the loop with the touch screen disappears. To check this, place an eraser over the area where the ribbon cable and shield meet. Press lightly on it and move the stylus across the screen. If everything works, then you can easily fix it. Cut a very thin and even strip of eraser, about 1 mm. Glue this strip in the place of contact of the cable with the screen with glue, which does not immediately freeze. If during reassembly it turns out that the screen has not recovered, move the eraser to a more suitable location.
Step 4
Reassemble everything in reverse order. Don't forget the microphone and pieces of tape if you left them for attaching the battery. Sometimes disassembly can lead to a "hard reset", for example, due to the fact that the auxiliary battery has run out. In this case, install Russification and start the recovery process.
