Hello, i'm a harmonious vision that brings you up to date every day
A few days ago, when he went out to do his work, his hands slipped and his cell phone was smashed on the concrete floor. Pick it up, and the top right corner of the screen cracks a large piece, and the thick web of spiders is spread out, and the touch is still working, and it's broken glass, and it's really hard to look at it. The master took a quick look at the maintenance shop near the house with his mobile phone and said that the screen would be finished at $800。
Listen to this price and i choked. This cell phone has been in use for more than two years, and the whole second-hand act is 1,000 years old, and it's 800 for one screen alone. The master also told me that this was the price of the original screen and that, if a third-party screen was selected, $380 could be replaced, but the display of effect, touch sensitivity would be short and could be cut and light leaks over time。
When i got home, i started thinking about the high price offered at the maintenance shop, a large part of which was manual and door-to-door rent. The internet often sees people buying their own screen parts to replace them, and i think that the phone has been broken, even if it fails, it can be used for repairing the shop, rather than trying to do it themselves. A total of 80 pieces of spare parts were spent on the internet with a test mind and the final set of spare parts together with the machine. It took over two hours. Take it easyScreen replacementIt has been completed and is now in normal use for almost two months without any problems of leakage or contact。
Today's experience of changing the screen in its entirety is not an incentive for everyone to fix their own mobile phones, but to tell you what's right for them to change the screen, what's wrong, what's wrong with dozens of screen parts on the internet, what details you have to look at when you do it。
First of all, there's a critical knowledge point that many people can't figure out: outside screens, inner screens, screens。
The outer screen is the outermost glass, which only protects. The fact that the outer screens are simply broken, the screens are intact and everything is in order only to replace the outer screens in isolation, at relatively cheap prices, and the maintenance shop usually uses separation devices to separate the broken outer and inner screens and re-press new glass. However, this operation requires a professional screen machine, which is not available in the ordinary home, and it is difficult for individuals to replace the outside screen alone。
The inner screen is the display and touch layer inside. Once the inner screen is damaged, the image is blacked, coloured, black spots, and tactile parts fail, and this cannot be replaced only by external screens, which must be replaced directly by the entire screen, i. E., the outer screen + the inner screens, and the whole screens must be bought and installed directly. Although my cell phone is full of cracks on the outside, it's all in order, and at first i thought it was just the outside screen, and then i realized that the reason for the structure was that it was very difficult to separate the outside screen, that it was better to buy it directly, and that 80 bucks was for the entire screen。
A lot of people here are wondering, what's a few hundred bucks for a maintenance shop and a few dozen dollars for the internet? What's the difference between the screens
The screens are broadly divided into three types, with original shredder screens, completely new original screens and third-party assembly screens。
The brand-new original screen, which is the same screen as the original cell phone factory, the supply channels are tightly controlled, the cost is high, and the maintenance shop offers 800, which is the type of screen, which is the same colour, touch, seal and all new machines, with the best quality。
The original machine screen, which was removed from the original plant screen, with second-hand fittings, at a moderate price and of a low quality, from the scrapped machine, has the disadvantage of showing traces of usage, and some of the screens may have a slight burn screen。
I bought 80 bucks for third-party assembly screens, compatible screens made in domestic factories. Such screens are low-cost and inexpensive, but of varying quality. A better assembly screen, with little colour, touch, does not vary; a different assembly screen, with a severe colour bias, delay in touch, and a weak light, can't see the screen, with a break in months。
Dozens of screens on the internet are mostly assembled. Don't expect to spend dozens of pieces, buy the same screen as the original plant, have a flat mind, it's a price choice, fit for the old machine, mobile phones are not valuable in themselves, do not want to invest in high maintenance costs and make temporary transitions. If it's a new high-end flagship phone, i don't recommend cheap assembly screens, which show a clear gap。
It is important to check the exact model of your mobile phone before the next fitting. Many mobile phone names look the same, screen interfaces, different sizes, and they can't be bought right. For example, the same phone series, the standard version and the pro version screen are not universal. When the order is placed, the complete model of the cell phone set-up is sent to the seller for confirmation and, by the way, for clarification of what is contained in the accessories. I bought this 80-dollar set of screens, a set of tools, glues, screen seals, and a scaffolding tutorial to get to work。
And before we get ready to do it, there's one more thing that's most important: the backup phone contains all the important information. While changing screens generally does not move stored data, there is an accidental risk of a maintenance process in which photographs and chat records on mobile phones are likely to be lost in case a line is accidentally cut and the main panel is short. Backup of important documents to clouds or computers in advance is much more solid。
I'm going to give you a quick look at the complete process of handing over the screen, so you can have a reference. The different types of operation are slightly different, and priority must be given to the matching course。
Step one, heat the edge of the screen. The cell phone screen and the middle frame are fixed by double-sided glue, which is softened by heat. There is no professional heating table, and the home is hot with a wind blower, which is spread along the screen for three to five minutes, and does not blow to the same position for long periods of time. High temperatures can hurt batteries and the main plate. Following the blowout, suction the corner of the screen, gently pulls a gap, inserts a shred of the dismantling machine and slowly removes the glue around it。
It is important to note here that the force must not be great. The edge of the broken glass is sharp, the pressure is so hard that the cracks can continue to expand, the broken glass slag may cut hands, the thins are not inserted too deep, and too deep they can cut the screen line。
Step two, open the center panel and break the battery line. A lot of people skip this step and pull out the screen line, which is a very dangerous operation. It is easy to burn a chip on the main plate with electric plugs to the screen line, and the main plate maintenance is a lot of money. In the correct order, when the back covers or screens are removed, the battery line is found, the battery is cut off with a crowbar, and then the screen line is removed。
Step three, remove the old screen and clear the old glue from the frame. Once the old screen is removed, a box in the cell phone will leave thick black glue, which must be cleaned up. If the old glue is not even, the new screen is sewn up so much that the presses are not tight and can easily enter ash and water. When cleaning up, do not scratch the middle frame with a sharp knife. It is easy to scratch the middle frame or even cut into the line inside. After cleaning up the new sealed tape completes the middle box。
Step four, connect to the new screen line, first test. The point is, the new screen doesn't just stick to death! Line up, button up the battery line and test the whole set. Checks if the colour displays are abnormal, there are no bright spots, colour lines, each location of the screen is insensitive, automatic brightness, and fingerprints (the fingerprint type under screen) are functional. All functions are confirmed to be fine, and seals are removed and the screen is pressed gently to fit the frame. Once it has been glued to death, the screen is found to be defective, and then it can easily be broken directly. When i tested it, i found a small touchy reaction on the edge of the screen that was slow, and immediately contacted the seller to replace it and avoid remaining sticky before finding the problem and turning back and forth。
Step five, stationary. When the screen is pressed in place, the cell phone is taped with a rubber band, the seal is secured, the glue is sequestered for two hours, and the glue is fully glued, and the screen is pressed hard and not just pasted. Extra spill of glue, wiped clean with no dust。
The whole operation was simple, and when you actually did it, you stepped on a lot of holes. I've sorted out a few of the top-screened mistakes of the ordinary people。
First, broken glass slag scratches the line. The old screen is badly fractured, and many small glass slags fall inside the middle frame when they are removed, and sharp glass can easily cut the screen line. After being removed, the glass scrape in the frame will be cleaned gently with a brush before proceeding。
Second, screw the mix. When the cell phone was removed, the screws varied in length, could not be interchangeable in different locations, long screws were torn into short screw holes, drilled directly through the main plate, and damage to the main plate was costly to repair. It's best to find a white piece of paper, to remove it, to place the screws and mark them。
Third, the crowbar overstretched the battery. Cellular battery casings are a layer of aluminium plastic film, and once punctured, the battery drum packs even start fire, with a high risk. Don't pry the battery when you're ready. If the battery is very strong, do not be hard, with a small drop of special-purpose degel softening battery glue。
Fourth, waterproofing is directly obsolete. Between the original cell phone screen and the fuselage, there is a layer of fine waterproofing, changing the screen itself, and a general tape on the back, which can only be protected from routine dust, so waterproofing is basically not an option. Once the screen is replaced, it is important not to take any more water to wash the cell phone, and it is easy to burn the main plate at any point。
After speaking of realism and objectively speaking of the advantages and disadvantages of changing the screen, one can weigh whether to do it or not。
Do your best, save your money. The old machine is always a few hundred dollars worth of spare parts and saves considerable maintenance costs. The whole operation went through, and there was a better understanding of the internal structure of the cell phone, and later the cell phone went down in the wrong direction。
The shortcomings are equally evident. First of all, the risks are high, and the lines referred to are broken, the screws are broken through the main plate, the batteries are punctured, and any failure, the cost of maintenance is skyrocketed and the cost of repair is not lost. Second, the assembly screen is less integrated than the original plant screen, and there are differences in colour, touch and utility. Also, after self-dismantling, the official security of the mobile phone is directly disabled and, if the mobile phone is still under warranty, it is important not to switch the screens。
Here's a simple choice。
Scenario one: cell phones are still under official warranty and the screen is damaged. After the official sale has been given priority, the self-dismantling machine is left without warranty and is not cost-effective。
Scenario ii: new high-end flagship aircraft with high overall value. Priority is given to the official original screen, or to the replacement of the original total by a simulator, where the low-cost assembly screen experience is very different and does not recommend its own replacement。
Scenario iii: using an old machine of two to three years, which is not of high value, it is viewed outside, mainly for daily communications, which is used to brush videos, has a good hands-on capability and can be considered for spare parts to replace themselves and save on maintenance costs。
Scenario four: the screen is badly fractured, the fuselage is clearly bent and the frame of the screen is deformed. Don't change yourself, the airframe is deformed, the new screen is attached to the edge, the press screen is prone to touch failure and is sent directly to the repair shop to correct the frame and change the screen。
Scenario 5: only external glass is broken and interior screen is intact. It is difficult to do this manually, without recommending personal operations, to separate the external screen, which can easily be broken directly by force, and which is more expensive to hand over to the maintenance shop for a separate external screen。
Many people have seen low-cost online spare parts, and the first reaction is that they are of poor quality and completely useless. You can't kill him with a stick. The domestic spare parts supply chain is now mature, and third-party assembly screens and basic use can be satisfied, but with little expectation. My 80-dollar screen, which is very smooth in short video and chats, is not as bright as the original screen, is slightly chilly and is not normally used. Of course, the quality of the spare parts at the same price fluctuates, with real buyers being evaluated before buying them, preference being given to supporting unprovoked, quality-assured businesses for seven days, receiving spare parts without being installed, as shown by a simple electrical test。
There is also a very realistic reminder that many of the low-cost screen campaigns on the internet, “same as the original ones”, are exaggerated. The idea of a penny-to-money delivery is equally valid on mobile phone parts, and dozens of pieces of spare parts are bound to compress costs in some places. It is not easy to be disappointed that it should be clearly positioned before it is purchased, as a low-cost transitional component, rather than as a substitute for the plant。
Following this successful change of screens, many friends have heard that the first reaction from a broken mobile screen wants to do it themselves. I'll persuade them to assess their ability to do it first. It takes care, steady hands, patience and no hastyness in the process. The sexual rush, the hand shaking, the friend who has never removed the electronics, is not recommended for direct intervention. The cell phone was lined up in a small and sophisticated way, and the glitch became a major failure, and more money was spent. If you are just trying to save money and don't dare to take it down yourself, you can buy it online and pay for it at the underline maintenance shop. Many repair shops are willing to pay only for it。
There have been two kinds of voices on the internet, some people sayMobile phone maintenanceThe windfall, the extremely low cost of spare parts and the high price offered by the door shop; the other part of the population felt that it was reasonable to charge hundreds of dollars for the maintenance shop, at the cost of technology, equipment and after-sale quality assurance. Objectively, the maintenance shop operates at a cost, and the master's maintenance work is valuable. It is replaced by a formula store, which is equipped with quality assurance and can be repaired free of charge for short periods of time. For the most part, the spare parts are replaced on the internet for only one month, and only the spare parts themselves, such as the installation of the main board, will not be the responsibility of the seller. The advantages and disadvantages of each option are not absolutely good or bad, depending on what is more important。
This time i spent 80 bucks on the screen, which was a smoother attempt, but it was only for specific scenarios, not for successful experiences that could be replicated by all. When the screen is broken, you don't see the price, you drop the parts immediately. The type of aircraft, the type of damage, the assessment of self-taught capability, and the decision as to whether the official after-sale, off-line maintenance or replacement of the shop itself。
