Necessary
operation manual and documentation for your device, light cloth, screwdriver set, soldering iron, alcohol, swabs
Instructions
Step 1
First you need to study the operation manual and documentation for your device. You should only repair your phone if the warranty has expired. If the phone is still under warranty, then you should contact the service center, where the device will be repaired. However, it is also necessary to study the list of warranty cases to make sure that the breakdown of your device is eligible for free warranty repair. If the warranty has expired or your case is not eligible for free warranty repair, then you can proceed to self-repair your phone.
Step 2
The operating manual always contains a list of some breakdowns, their symptoms and solutions. If your case is on this list, then follow the instructions given. If your malfunction is not on the list, then you will have to disassemble the device. You need to try to understand what the malfunction is. For example, if you spill any liquid on your phone, you should take it apart, clean it and put it back together. Unsoldered wires can also cause damage. So, lay a light-colored cloth on the surface where you will disassemble the device so that all small details and screws are visible on it.
Step 3
Disconnect the telephone and power cables from the machine. If the tubing with the wire is detached from the housing, remove it as well. Flip your phone face down. On the back panel, you should see the holes where the screws are located. They can be closed with special plugs. Remove all screws. After that, find the plastic clips that hold the case. Open them and separate the case in two. Do everything smoothly, as thin wires can connect the two parts of the case.
Step 4
Examine the insides of the phone. If you spill liquid, you need to disassemble the phone as much as possible. Carefully clean all microcircuits with tampons with alcohol, the plastic parts must be rinsed with plain water. Let all the details dry. Pay attention to all contacts. If you find disconnected contacts somewhere, they need to be carefully re-soldered. After that, reassemble the phone in reverse order and check its functionality.
