Some Solutions about the Splash Screen Problems of Mobile Phones

Is the touch screen on your Android cell phone unresponsive or responding incorrectly? Do some parts of your phones screen respond while other parts do not?  Many repair shop owners may encounter this situation: after turning on the replaced screens, many flickering vertical lines appear on the screen. Here I will share some possible solutions with you.

 As a matter of fact, these problems may happen in the following situations.

The first one is more likely to happen during the repair process. When there are tiny stuff (such as dust or broken glass pieces) between the LCD connector and motherboard connector, the LCD screen can’t receive the correct data to work. What’s more, when the connector was not assembled correctly and be pressed deformed, the tiny so called “gold fingers” in the gap between the connectors that get corroded may also cause the problem.

The solution to solve it is simple, first, check whether the connectors are connected correctly. If so, clean the connectors by using 530 contacts cleaner. With a little brush dipping some 530 contact cleaner, you can clean the connectors clearly. Handle gently, or the circuit may be damaged. If the stripes are still on the screen after you have cleaned the connectors and reassembled the parts, replace the connector. It may solve that problem.

In the second situation, if the four corners of the LCD display have been crushed during the repair process. The only thing you can do is to replace another LCD screen.
