Dude, ask a question about mobile phones?

How bad was the original screen?

If the original screen can still be turned on, it can still be lit. Then you can switch back to the original screen and see if there is any problem with touching with the original screen.

If you replace the original screen and the touch does not respond, it proves that it is not a screen problem. Either it's a circuit board problem, or a technical problem with changing the screen (forgetting to plug in the cable, or plugging in some loose cables).

If there is a response when you replace the original screen, it proves that there is a problem with the new screen.

Now the problem of smart phones, although there are many kinds of them, but in general, the quality of smart phones is still very reliable, unless it is specially used for electric boards, especially fast, that means that this mobile phone is old, and there is also an information clerk What is called a male electric board can not be repaired? So a lot of it is really weird.

There are two reasons, one is that your touch screen cable is not installed properly, and the other is that there is a problem with the screen itself.

In this case, the biggest possibility is that the cable clip of the touch screen is not installed, and there is a possibility of false connection.

There is also a quality problem with the screen itself.

Then the screen cable may be falsely connected.

The first thing to do is to make sure that the new screen model matches the phone; 2. Confirm that everything is normal on the new screen (display and touch) 3. Make sure that the screen cable is installed in place (there will be a "snap" sound when you press the cable base to the buckle, which means that the installation is in place) 4, that is, the touch circuit is broken.

Summary. Please refer.

The other party saw me on the side, too.

If there is any problem with your mobile phone, you can send me your question to see.

Question: This streak appears on the phone.

Wiring problem: The mobile phone cable is used to connect the mobile phone motherboard and other modules, and the mobile phone has a blurred screen and color stripes, which is likely to be a problem with the screen cable. In the past, cable damage generally occurred on sliders and flip machines, but straight smartphones have rarely encountered this situation.

However, if you have dropped your phone before, or continue to use it when the heat is severe, it is likely to cause the cable to loosen or even burn out, resulting in abnormal screen display.

The inner screen is damaged: the outer screen (surface glass) of the mobile phone is broken, and the screen display and functions of the mobile phone will not be affected; If the inner screen of the mobile phone is damaged, it is more troublesome, not only the touch function may fail, but also generally accompanied by the mobile phone screen display problems - in addition to color stripes, dark spots, yellow spots, flickering and even failure to display may occur. If your case is that the phone falls and the screen is streaked, then the inner screen is most likely to be damaged.

Ask how much it costs to fix it.

Ask questions if you're on the inside screen.

How much does it cost if it's an inner screen.

Ask a good question, thank you.

You're welcome to help you, it's my pleasure.
