00:00:03,033 --> 00:00:05,900

Next, I will introduce another method to fix

2

00:00:05,900 --> 00:00:08,666

the popup window after replacing the screen

3

00:00:08,800 --> 00:00:13,433

The previous method is to move the touch chip from the bad screen to the good screen

4

00:00:16,833 --> 00:00:20,200

Now this way is to connect the touch chip on the bad screen

5

00:00:20,200 --> 00:00:23,200

to the interface of the mainboard through jumping wire

6

00:00:27,466 --> 00:00:31,366

The advantage is that if the screen is damaged again in the future,

7

00:00:31,500 --> 00:00:33,600

we don't need to move the chip anymore,

8

00:00:34,000 --> 00:00:38,166

we just need to replace a new screen and plug it into this interface,

9

00:00:38,633 --> 00:00:40,400

and it can be used directly,

10

00:00:40,600 --> 00:00:42,666

there will be no popup windows

11

00:00:44,733 --> 00:00:47,366

This method is done once and for all

12

00:00:47,933 --> 00:00:52,133

To use this method, it is best to be proficient in soldering

13

00:00:53,333 --> 00:00:54,566

If you are not skilled,

14

00:00:54,633 --> 00:00:58,233

it is best not to use this method to avoid damage to the mainboard

15

00:01:06,200 --> 00:01:09,833

First, we tear off the foam tape next to the screen interface

16

00:01:31,600 --> 00:01:35,500

And the foam tape at this position is also torn off to prevent

17

00:01:35,500 --> 00:01:38,300

the high temperature from blowing the foam later

18

00:01:48,366 --> 00:01:53,033

Take the air gun to blow it, straight air gun or rotary air gun can be,

19

00:01:53,400 --> 00:01:56,000

the lowest temperature of 100 degrees,

20

00:01:56,300 --> 00:01:58,100

the largest air volume

21

00:02:05,600 --> 00:02:09,066

Clean the black glue on the surfaces of these components

22

00:02:11,433 --> 00:02:14,000

This kind of black glue is relatively soft,

23

00:02:14,500 --> 00:02:16,766

it will loosen with a little temperature

24

00:02:41,666 --> 00:02:44,333

The tip of the tweezer must be round and blunt,

25

00:02:44,633 --> 00:02:47,133

otherwise it will easily scratch the mainboard

26

00:03:13,633 --> 00:03:15,466

Okay, let's clean it up a bit
