One day, a friend told me that there was a broken screen in my home. I wanted to see if I could help change the screen because I love tossing digital, electronic, and the like. It was already spread among friends around me, so I said Let me take a look and say it again.
After a few days, I passed it to the outside one evening and gave it to me. It was like this when I reached my hand.
At that time, the light was not good. I didn't look carefully. I asked my friend. This is the LG curved screen mobile phone. (I thought it was the following goods)
The result friend said: What, this is Huawei. When I got the light and saw it, I saw Huawei's G7. But this is only a broken screen, it is simply a return on the battlefield.
The front has been appalling
One corner has very serious collision marks
The top has also been opened
The key is that the phone has become a curved surface
The friend said that it was a quarrel with the wife and it was a bit like looking at the damage in that corner. However, after seeing so many mobile phones that fell, it was the first time I could break into a curved surface. This is obviously the result of sitting in the back pocket of the trousers and then sitting on the sofa. However, how to deal with it specifically, you can't control it. He asked me to bring it back and give it a try.
But at that time, he said to him, like this, there is no guarantee that the internal motherboard and the like are not damaged, and the back shell is also bent, I have to go back and see it, there is no problem inside, and the back shell can be restored before changing screen .
Because Huawei's product line is very wide, in addition to those models that are widely advertised on the market, many of Huawei's mobile phones are not equipped with the same numbers. This is also true for the G7. Checked back and found that this phone is listed on the 14th, it seems to be selling 1999, but look at the configuration, also with the red rice Note that year. However, it still has to be about seven hundred.
Before you remove it, you must first boot and see if there is any problem.
The use of the boot, found that the internal screen is not broken, the application of the system, including putting, front and rear cameras are normal. Although the internal screen is not broken, but like this full-fitting screen, there is no professional separation device, or do not want to change the touch screen alone.
The following opening, first remove the two SIM card slot
The two plastic decorative sheets on the back and the back are glued on both sides, and they will be removed directly.
After unpacking, it was discovered that the horn had sucked a pile of iron scraps. It seems that the original working environment of the mobile phone is worrying.
Take out the tools and wait
The snaps in the rear shell and middle frame have been thrown apart. After unscrewing the six screws on the back and back, it is easy to open.
After the metal back cover passed my hard work, it was finally flat again.
The back cover is flat, but the middle frame is still curved. To change the screen, it is better to change the screen with a frame. Otherwise, the middle frame is uneven, the light changes the screen assembly, and the time does not fit, or give the screen a crack again. It's worth noting.
Checked on Taobao, with boxes in one hundred and three, four. At the same time, in view of the performance of this mobile phone, it is necessary to confirm again whether he wants to change screens. He gave a positive reply and decided to change. Because this time bear children are on holiday, and his son is the same, usually go out with the child, and when the child is bored will take his 6P to play the game, as if to give him a fall, so he will give this The change of screen for the mobile phone is to give his son play, so as to avoid playing with his mobile phone again.
So on the Taobao to find a 130 yuan, placed a single.
And these disassembled, also must first dismantle the battery (because already disassembled, prevent the short circuit of the component on the main board), close and wait for the new screen to arrive. Generally speaking, mobile phones with built-in batteries have batteries that are glued to the middle frame with double-sided adhesive tapes. When the batteries are taken, they are very difficult to pick up. Thanks to this fall, the batteries are easily taken down.
Waited for another three days and finally received a new screen. Such packaging is still very reassuring.
He also sent two small screwdrivers and a tempered film, but forgot to shoot.
With the middle frame, it is very convenient to replace it. You need to remove the cable at the top earphone and the middle screen cable first, and then unscrew the three screws fixing the motherboard, and then gently press the several cards that fix the motherboard. The buckle can be removed, and then the receiver, earphone jack, distance sensor, and exoskeletons in the red frame below are moved to the middle frame of the new screen.
After that, install the motherboard, and then connect the battery to try the machine. At this time, the battery should not be fixed.
Normal boot, no problem in the system into a variety of test touch, the show is OK, by the way to run a minute.
All aspects are determined to be no problem, and then fixed batteries, the same is to use double-sided adhesive to stick.
Put on the back shell, the previous step is reversed, screw the screw, and then the two decorative sheets are glued with double-sided tape and finished.
Look at the front, like the new one. Tempered film also helped him paste it, and it can be handed to the bears.
Finally give some advice:
No matter what brand or model of mobile phone or tablet, if you want to change your screen, you must first find a teardown diagram. It is even better to find a teardown video.
Remove the screws must be put, if the specifications are the same, can be stacked together, if the specifications are not the same, it is best to separate, and make records, to avoid the back of the installation because the screws do not match the phone cause greater damage.
The back cover of the mobile phone generally has communication antennas, WIFI antennas, and contacts such as Bluetooth antennas. Before the back cover is replaced, it is best to put each contact up slightly to make it easier to follow the main board. Contact contacts, so as not to find the signal is not good after installation, have to open again.
