Hello, friends today I’ll discuss Samsung b310 mobile network problem solving We will discuss how to solve the solution. First of all, I tell you what is the problem with this mobile network, that is why I will discuss it first and I will explain how you can solve this problem.
What is the reason for this?
See the network problem that this mobile device appears on the mobile network antenna. This problem comes from Crystal or network filtering. So I’ll tell you here step by step that you can solve this problem. I discussed these steps below
Solution Method:
To solve this problem, first, you have to open the mobile. After opening the mobile, the motherboard that has the motherboard on the motherboard should be cleaned well. And after cleaning the motherboard, you must first check the antenna lining that has the network antenna on the mobile.
check, how do you do that also I am telling you to set the range of multimeters in the range to check the antenna lining. Then a poll network of network of meters in the Network Antenna, where you have to start from the output of another poll network IC output that continuity comes here if continuity does not come then you have to do a jumper here. JUMPER How do you do that picture I gave it here by jumping the picture and then the mobile should check if the network is coming. If the network does not come, network filtering crystal will need to be changed.
Step By Step:
- First, open on mobile
- Then clean the motherboard of the mobile
- Then check network antenna and network antenna lining well
- If network antenna lining is not right then network ic antenna output to network antenna jumper
- And then check the SIM with mobile phone
- If you do not have a mobile network after this, then change the network filtering crystal
