I believe many of my friends' mobile phones are the most vulnerable to the screen, and the mobile phone screen maintenance costs are generally higher, everyone does not know, in the phone tends to be modular, highly integrated today, mobile phone change screen is a very simple and easy job, generally Skilled men who have a slightly stronger ability can do it. In addition to saving money and getting this skill, I waited for a group of DS to repair the computer in addition to the goddess, and she could also change the screen for the goddess. It was a beautiful day.
One, the screen changed in these yearsBecause they are interested in digital products, they have been paying more attention to the mobile phone industry. It happens to be related to electronics, but also spent time in the electronics factory's assembly department and the SMT department, especially when they were responsible for the management of an SMT workshop at an electronics factory in Dongguan. , SMT machine is old, familiar with the maintenance staff and relatively short-necked, it is hard to put yourself into a PCB maintenance master + soldering iron master: more than 100 feet of the IC do not have a hot air gun with a soldering iron can also get - so the hands ability has been relatively strong , so close relatives and friends of the mobile phone crash screen are my hands to get, deeper memories of the phone over the past few years have changed screen: ZTE U880, Apple 4, Meizu MX4, glory 3C, HTC new desire T328D, HTC G7, There were several of these items on Taobao, and they had been to Huaqiang North two or three times to buy screens in Shenzhen. There was no record:
There is this Huawei P7. Well, if you are unemployed someday, consider taking a film and changing screens on the flyover.
Second, the situation before the screen change and purchaseThe machine that needs to change screens is an old machine of my sister: Huawei P7.
To be honest, Huawei’s machines are based on cost-effectiveness and domestic competitive products. I have never recommended it, but if friends and family want to buy me for advice, I will only tell the other party: If I buy my own mobile phone, I’m on the same budget. I am more inclined to buy what kind of machine, the budget does not matter then eat fruit. If people have come to ask me the specific model, then I will not say any more: I like to buy it, so generally I will ask you what you want to buy, and then what to buy it, a mobile phone, there is reasonable - Someone will always like it. If you don’t like it or buy it, if you don’t have the money or don’t want to change it, then you’re embarrassed: Your favorite machine, with tears, you have to use it.
Because there are children in the family, most of the time use the protective cover, who knows that the protective cover is also difficult to resist bear children, the bear children played the machine is not dead or residual ah (tears because my tablet is also very disabled, please refer to me Idle stickers)
The comminuted fracture of the earpiece, the screen touch layer has cracked
Too bright to show screen cracks, photo low light
Because there is a protective cover, the back is still very smooth, so to see such a beautiful back, simply change the border of the broken it, be regarded as a renovation
The girl had already changed Huawei G9 (she is Huawei powder), but this machine feels that I can send some light and heat (such as playing games for children to watch cartoons), so I asked me to change the screen for backup. Originally planned to change the screen, get the machine to see the border is also relatively old, change the screen 120 +, the box and the screen will also change together with 150 +, so simply do not do endlessly, the screen and the border are changed, More than 30 pieces can be exchanged like a new machine, value!
Purchase principles and precautions:
When you buy the screen assembly in the counterfeit cloud home, search for 75 pages of information. How to choose?
1, choose a higher number of sales, more comments:
A certain treasure is more than a fake, the more single, so see the figure below this kind of sales is not directly proportional to the comments, brush list is no doubt , in addition, but also to see if there are no reviews and assessment , There is a poor evaluation of the normal, if the sales of hundreds of thousands of thousands but it is full of praise, it is too fake.
2. The screen assembly is generally not fake:
In general, the election of higher sales, and there are real evaluation, occasionally there are several bad reviews in the evaluation, blueprints is more reliable, anyway, are Shenzhen Huaqiang North's goods, there will be no "false "Or all of them are fakes - anyway, there will be no original goods, they can all be used, and the experience can reach 80-90% of the original factory.
3, do not superstition original original, more than 90% are Huaqiang North high imitation goods :
The original screen is generally more expensive, when a friend bought the Taiwan National Bank HTC 4000 yuan (around 2011-2012), the next day the screen was broken, to sell after the original screen, quote 1700+ Change. Just like this Huawei P7 machine, although it is the flagship of two or three years ago, to the official after-sales point offer at least have to be between 280-400 yuan, so more than 100 screen Taobao is Huaqiang North's goods
I bought this boss smart, did not say it was original, it is the original goods (usually consumers will understand the original goods), Oh:
4, there is a small amount of bad reviews is normal, the key is to look after the attitude
After all, Huaqiang North's goods, quality assurance can only be Oh. There is a negative assessment in the affirmative, and it is important to look at the after-sales attitude. Look at the seller before selling repeat that as long as it can be returned, at least pre-sale attitude is also OK, bad review of the reply attitude is also good, for the time being believe it (PS: bright spots in the figure)
Screen packaging is also good
The protection is not bad, there is a bubble bag package, even the tools sent are wrapped up
Send tools: suction cup, screw, small film, double-sided adhesive
After getting the screen, do not rush to install, first check: Taobao screen front, the front has posted a good tempered film, according to the previous screen-changing experience, Taobao's screen surface glass is very easy to break, much worse than the original screen
Taobao screen on the back: to get a hand feels much worse workmanship
After all, Taobao goods, workmanship is relatively poor, there are three plastic borders sticky plastic, border plastic work is not as good as the original factory, see this work, a little unsatisfactory
Although the work is a bit poor, I think after all, it is Taobao goods, as long as the screen shows OK, then it will use it.
Well, start disassembling. For the all-in-one, the back cover is difficult to remove, this section P7 back cover is double-sided adhesive, first with the hair dryer on the back with a large wind and hot air blow, and then use the suction cup to open the back cover, and then use to send The film is opened a little
Pull a little bit, and then use the film to send a little open (do not use metal tools æ’¬)
When the cover is removed, the shield is also glued down
Remove the back cover and the whole picture (the shield has been installed on the main board)
Remove the card slot and then take the next step
When the screw was removed, it was found that P7 had three kinds of screws. I never paid attention to the screw bit before. I actually designed it.
The handset is not very easy to dismantle, and the receiver accidentally disassembles the handset in half (but it is better to find it early. The wire with the thin wire inside is not broken, but it can be used when it is installed)
Then slowly dismantled, without detailed photographs, directly on the photo of the disassembled parts (forget to look good shot)
Original box and Taobao goods
When you are ready to move parts to the Taobao screen, I think it should be installed screen test screen is not good, only the battery pressure up, put the board up on the line, no screws to hand letter pressure
Installed to boot, well Taobao screen is Taobao, full of sense of the cottage, there are two obvious white spots, the screen will be a little leak, see here, I intend to return, not to return, but this Screen from the feel, the screen quality can not be satisfied, completely unable to live with its 150 + price.
Contact Taobao merchants, the other party began to say that they can exchange goods or return some money, but I very much doubt that their family's goods are so, so when asked further, the merchant finally said that his family's goods is like this, so he applied for a return.
So he tossed it one night and loaded it back.
Pay attention to the length of the screws when loading the screws
Install the antenna cable before installing the screws. When the screws are lazy, the related information is squeezed on the side. The result is that if the cable is broken, there is still a signal after the test. However, it is estimated. In the future, it will affect the signal.
Put it back, or this broken screen
If this screen is not too bad Taobao, to complete the screen here. Still decided to go to find a friend, from the factory to buy after the original block to put it, but the cost may be 200-300 pieces.
For the screen change, I was very cautious, but I was very careful, but there were still two neglects: the handset was almost scrapped and the antenna cable was broken. Still can not take shortcuts, can not afford to trouble trouble ah.
In addition, the P7 and the FPC of the switch must be carefully removed, but the manufacturer adds a small piece of iron to the back of the FPC to increase the strength when designing, but it is necessary to be careful when disassembling.
Nowadays, because of the reduction of Baidu and high integration of mobile phones, many circuit boards use soft FPCs, especially cables, and in order to fix them, the thin FPCs are usually stuck in the middle frame with double-sided adhesive tapes. Use brute force, but also try not to dial with a metal tool such as a blade, easily damaged. You can use a hair dryer to blow the soft double-sided tape first, and then gently lift it.
Mobile phone motherboards should also pay attention to, now on the motherboard resistance and capacitance and other parts are smaller than sesame seeds, touch less is better.
Finally, Huawei P7's workmanship is still good, the middle frame using metal + injection molding, to ensure the strength of the middle frame, and the plastic frame part of the frame to reduce the weight of the fuselage.
Well, there is one more thing. If you see it, thank you very much. Please also pay your grandfather a little bit of money.
Value friends, again!
