DIY repair of asus nexus 7

In detail: do-it-yourself repair of the asus nexus 7 from a real master for the site my.housecope.com.

Today we will tell you how to disassemble the Asus Nexus 7 2013. This is the second version of the device of the same name released in 2013. The instructions described in this article will help those who decided to disassemble this device for self-repair, prevention, etc.

We do not recommend using it for those who do not have experience in parsing modern mobile devices and skills in carrying out repair work. If you have firmly decided, then let's get down to business.

In the first step, we need to remove the back cover of our tablet. To do this, you can take a solid pick, a plastic spatula, or a smooth dental instrument (which I actually use most often) so as not to scratch the plastic during work. We insert the spatula into the gap between the back cover and the frame around the display and gently release the latches, as shown in the picture.

We move down the perimeter and do the same at the bottom of the tablet (where the system connectors are) and on the opposite side.

Having released all the latches, we dismantle the back of the case.

Finally we got to the guts' guts. Now we need to remove the battery. To do this, we disconnect the wide silver ribbon that connects the main board to the bottom.

Then we disconnect the display cable. He's a little narrower.

After that, unscrew the four bolts securing the battery on the sides and remove the battery by disconnecting it from the connector.

Next, we move on to the bottom board. Disconnect the polyphonic speaker and the loop from the touchscreen from it.

Unscrews all the bolts fixing the scarf around the perimeter and remove it

Remove the polyphonic module by unscrewing two bolts in the corners.

We do the same on the main board: disconnect the polyphonic speaker and the side button cable.

We unscrew the bolts around the perimeter and dismantle the motherboard, and behind it the upper polyphonic block.

That's all, the entire tablet can be considered disassembled.

On our own, we advise you not to risk it and contact the service center. If you break the touch glass on the Asus Nexus 7, the device stops charging, does not boot, or asks for a graphic password, our wizards will put it in order within an hour. In addition, you will receive a guarantee for a period of 30 days to 1 year.

for a start I will lay out the diagram of the tablet itself (in the attached files).
There was an idea to implement a built-in sd card reader for nexus 7.
the idea is that you can solder to the usb connector on the nexus and bring the reader out with a switch. but thoughts torment:
1. how to charge the tablet so as not to disconnect the USB flash drive. (I already have an idea. 4 contacts on the verge know how to charge the device. Also in addition, a clipping from the diagram) + link to the kernel, which allows you to charge the device at the same time using the release.
2. to see all the contents via usb. including the connected SD.
who have ideas, let's share them. and other ideas.
now studying the circuit.
ps noticed that you can solder the hdmi connector, there are connectors on the board.
PSS: sorry for the fact that everything is written in a bunch like that, as the topic is added + I will supplement and maintain a post.

Asus Nexus 7 2013 users, while using the device, often have questions related to possible problems and actions that should be taken to resolve them. Of course, not all problems can be solved at home and, in extreme cases, you will have to contact the master, but the repair of the faults encountered can be carried out on your own.

If the Asus Nexus 7 2013 is fully charged, but does not turn on, then the solution to this problem is quite simple: connect the tablet to power for several hours and hold the power button for at least 30 seconds. This uncomplicated process will fix the device after a deep discharge, which previously refused to start.

Many people complain about the screen rotation not working on the Asus Nexus 7 2013. To fix this problem, first make sure that the auto-rotate function is turned on - this can be done in the "Accessibility" tab. Click on the "Power off" button to go to safe mode - if the screen rotation works, then the problem lies in third-party applications, which can be removed with a soft reset.

If you encounter an issue where the Asus Nexus 7 2013 won't charge, you should connect the charger, press the power button and the volume down button at the same time. In the menu that appears, using the sound adjustment, go to the "Power off" item and press the power button. Reconnect the charger and then you will see the battery charging icon.

Have you found that the computer cannot see Asus Nexus 7 2013 when connected? In this case, you need to start USB debugging: find the "About Tablet" section in the settings of your tablet and click on the build number until the developer options become available; go to the options that appear and enable USB debugging, and do not forget to update the drivers in the appropriate section on your computer.

If you connected the Asus Nexus 7 2013 to a computer via USB, but it does not recognize it, then this problem can be solved as follows: go to the settings and select the "Memory" menu, click on the three vertical dots in the upper right corner and activate the connection to computer via USB. Make sure Media Device is checked, and then reconnect your tablet to your computer.

If the screen of Asus Nexus 7 2013 does not display images, then you need to find out the cause of the problem. Connect the device with a cable to the TV using the video output (HDMI). Make sure your tablet is turned on: makes sounds when you press the volume buttons. If the image displays normally, the tablet screen needs to be replaced.And if it is not there, then the reason is a faulty video adapter unit, and the device must be taken for repair.

To replace the damaged touchscreen on the Asus Nexus 7 2013, turn off the tablet, remove the cover with a special plastic tool (if it connects to the body with a ribbon cable, then disconnect it), then evenly heat the display with a hairdryer, gently pry the old touchscreen with a knife, pull it out and put a new part onto your device, fastening it tightly.

To replace the display, you need to open the case of the Asus Nexus 7 2013 with a plastic pick. Disconnect the two main flat cables of the tablet with tweezers and remove the battery from the device. Use a screwdriver to unscrew all the screws to pull out the daughterboard and micro USB, similarly remove the motherboard. Next, you need to warm up the glass of the screen and use a sharp blade to separate it from the glue. You need to carefully stick the new display onto the cover.

Replacing a faulty battery in an Asus Nexus 7 2013 tablet is easy: open the case with a plastic spoon or knife, disconnect the transparent and orange cables from the board, unscrew the screws around the battery case, insert a plastic tool under the side edge of the connector and pull it out, securing the new battery in this place.

Asus Nexus 7 2013 users are often faced with the fact that the tablet freezes on the Google logo. To fix this problem, hold the power button for 15 seconds, then reboot. Repeat the procedure three times, and if the problem persists, then in the "About Tablet" menu, check for system updates and install them, if necessary.

The Asus Nexus 7 2013 can hang when unlocking the bootloader for many reasons, but the main one is not enabled USB debugging. This can be fixed by running the bootloader and connecting the tablet to the computer, then access the system with administrator rights using a special utility and enable the desired function in the developer options.

Asus has released a new version of the Google Nexus 7 2 Gen 2013 tablet

In this article, we will try to briefly tell you how to disassemble this tablet.

The technical components for the Asus Google Nexus 7 2 Gen tablet are:

Qualcomm 1.5Hz Snapdragon S4 Pro Processor
7-inch touchscreen display with a size of 1920x1200 with an IPS matrix
2 GB of RAM
Graphics adapter Adreno 320
5MP rear camera
1.2MP front (front) camera
operating system Android 4.3 Jelly Bean

Comparing the second generation Nexus 7 with the first, we can see dramatic changes in the shape and size of the device.

The second version (pictured on the left) is thinner, narrower and taller (longer) than its predecessor, and there is no corrugated texture on the rear panel.
The next obvious changes include the addition of a rear camera and an update to stereo sound. There are now three lattices here (acting as two columns): two at the base and one at the top.
That said, there is a feeling that although the micro-USB port has remained in the same place, the headphone jack has been moved.

In the second step, we move on to opening the tablet using a special plastic tool.

When you find yourself inside, don't be surprised: you will find a huge battery. However, it is fairly standard for modern tablets.

There is something else inside. Antenna? (Inductor?)

Note that this is the first time an antenna was present in a tablet with a touchpad. Perhaps in the future, we will get rid of wires altogether as sources of e-waste. By the way, there is also an NFC module * - right above the inductor.

It's time to use the spudger ** to free up the battery.

The cover in the Nexus 7 is held in place by two screws - one on each of the main shields - and, I must say, are held so tightly that replacing them will most likely void the warranty.
But we decided that our opening process was more important than guarantees.

The battery stand comes out without problem.
It is held in place with just a few screws, although the battery itself is attached to the tray with some pretty sticky glue.
Battery with a voltage of 3.8 V, capacity of 15 W / h (3950 mAh), with a charge voltage of 4.35 V, created by Celxpert Industrial Corporation.
Despite the 4326 mAh (milli-ampere per hour) battery of the original Nexus 7, this new generation of batteries boasts an extra hour of battery life. Low power devices are much more profitable and give more bang for your buck, so this is definitely a good trend.

It's time to remove the daughterboard, with only one IC (Integrated Circuit) located between the connectors at a fixed location.
ELAN eKTH325BAWS is a capacitive touch panel controller from ELAN's eKT line (ELAN Microelectronics corporation).

We removed the motherboard just as quickly as in the previous operations. The front and rear cameras are also easy to reach.

It is a pity that users continue to take awkward tablet photos at this level of the device.
For unique shots taken with your new Nexus 7 tablet, you get a 5MP (megapixel) image. For selfies, you only have 1.2 MP.

So, what is the "stuffing" of this tablet (PCB)?

Qualcomm APQ8064 Snapdragon S4 Pro Quad-Core CPU
4 x 512 MB RAM (total 2 GB) - Elpida J4216EFBG DDR3L SDRAM
Microcircuit Analogix ANX7808 SlimPort Transmitter (responsible for video output)
Texas Instruments BQ51013B Wireless Charging Controller
Wireless IC - Qualcomm Atheros WCN3660 WLAN a / b / g / n, Bluetooth 4.0 (BR / EDR + BLE) and FM radio module
16GB Flash Memory - SK Hynix H26M52003EQR eMMC
Qualcomm PM8921 Power Controller Fast Charging Battery Management IC (Integrated Circuit).

Next, we extract the updated speakers.

They are stereo and have high sound quality.
Their marking is DN17128L000.

Inside the front panel we find the outputs for the Wi-Fi antenna.

Moving step by step, we find wireless frequencies with the symbols "ME571K_WIFI_3DC"

Let's sum up - and evaluate the second generation Nexus 7 tablet according to the maintainability criteria.

Rating: 7 out of 10 (10 points are given to a device that is very easy to repair).

The back cover opens quite simply, requiring minimal effort and using only an available plastic opening tool. True, as you noticed, we slightly violated the integrity of the device, although we were rather careful at the beginning of the parsing procedure.
All fasteners inside are Phillips Phillips screws - there are no proprietary (proprietary) screws here.
Since the battery case is easy to remove, some particularly meticulous "openers" will definitely need to pull it out of their cradle.
The front glass is glued to the display bezel, which means you still need a heat gun (or hair dryer) to remove the display or completely replace the front bezel.

We continue to publish daily instructions for repairing Asus brand tablets, and in this material we will tell and show in photos and videos how to replace a broken Full HD screen (7 ″ diagonal, 1920 × 1080 resolution) with a very good one (in our opinion, one of the best in its niche) tablet ASUS Google Nexus 7 2013 ME571 (other markings of the device ME571K, ME571KL, K008, K009).

You can watch the video of the process of replacing the display module, located below in the text, or go through the stages of describing this process with text and photographs.

Before us is a Nexus 7 tablet with the most common problem (broken touch glass), in this case we will change the entire screen module of the tablet. First, with the help of a pick, we dismantle the back rubberized cover of the tablet computer.

In the next step, carefully disconnect the cables.

We warm up the display surface, at the places where the screen is mounted with the case of ASUS Google Nexus 7 2013. We slowly dismantle the display.

We remove the remnants of the old glue and degrease the surface. We glue the place of installation of the display with double-sided tape.

Next, we connect a new screen module to test its performance.

We remove the protective films and mount a new tablet screen.

Be careful with the display cable.

We mount the back cover of the Nexus 7 2013 tablet.

We turn on the tablet computer again to make sure once again that the new screen works without problems, and the touch glass in the tablet reacts to touches without “phantoms”.

As the world sales statistics show, today one of the most popular tablet computers is the Nexus 7 - a joint product of companies such as Google and ASUS. Enthusiasts have already studied the tablet from almost all sides, and often publish their review on the Internet.

A foreign resource called DirectFix.com has posted a video tutorial for disassembling the Nexus 7, which can be viewed below. It allows you to understand the best way to open the case of the device if you suddenly need it.

As noted by the authors of the video, the build quality of the tablet is at a fairly high level. On my own I would like to say that site users When commenting on the display defect, they often write about the absence of some screws. I wonder why the developer doesn't have control over this?

If for one reason or another you need to disassemble your Nexus 7 tablet, then visual instructions from DirectFix.com will help you do everything right.

The case can be opened very easily. Most of it is occupied by a large battery, the capacity of which is known to be 4325 mAh. The motherboard is L-shaped. In its upper left part there is a central processor called "Nvidia Tegra 3 T30L", a Broadcom GPS receiver, an InvenSense accelerometer, an NFC chip, and a Max 77612A voltage regulator. Also inside is RAM with a volume of 1 gigabyte.

Video instruction:

Undoubtedly, the most popular tablet in the world today is the tablet co-produced by Google and Asus - Nexus 7. The tablet has been studied far and wide, described in many reviews and disassembled into its component parts.

We have already introduced you to the instructions for disassembling the Nexus 7 in pictures, but the video instructions from DirectFix.com will allow you to better understand how to open the tablet case and what is inside the device.

The tablet has a very decent build quality, although some of its owners were faced with a situation where falling from a low height caused the tablet to break. If you want to try and repair your Nexus 7 yourself, then the instructions from DirectFix can be very useful to you in this situation.

The authors of the video confirm that falling on a hard surface can cause serious damage to the device, and if you have no experience with such equipment, it is better not to try to repair the tablet yourself.

The case of the tablet is quite easy to open, and inside it, most of the space is occupied by a powerful battery with a capacity of 4325 mAh, which provides the device with 9-10 hours of continuous operation. The battery is fairly easy to replace - it is held together by a couple of drops of adhesive.

The device has an L shaped motherboard that is secured with screws and has many connectors. All this can be easily understood using simple tools.

Inside the tablet we find 1GB of DDR3 H5TC2G83CFR RAM - the same type of memory found in the MacBook Pro with a Retina display. In the upper left corner of the motherboard is one of the two microphones, and in the same place, on the motherboard, there is an Nvidia Tegra 3 T30L processor, a Max 77612A voltage regulator, an Azurewave wireless module, a Broadcom GPS receiver, an NFC chip, and an InvenSense gyroscope and accelerometer.

To date, the budget Nexus 7 tablet of the first generation has already been about a year and a half since its presentation. Since then, many lucky ones have had the opportunity to use this device, use it with all their might, until exhaustion, until they get bored, or until the screen crashed. Something like that happened to me.

I used my nexus without shame or fear: I threw it on the bed, carried it at the bottom of my backpack, put it under my pillow at night, and so on. I used it mainly for surfing, a couple of games and more recently for reading books. It was while reading a book in the bathroom that I short-circuited the charging socket, after which terrible spots appeared on the screen. The first solution was to disassemble and dry the drowned man, but this did not help, and it seemed to me that if you separate the matrix from the glass, the effect would be stronger. He unrolled, disassembled, picked out, turned off, picked it up! I was digging in the sense that, as I found out later, that matrix is simply glued to the glass and cannot be separated just like that, so it cracked.

How to Replace Nexus 7 2012 Display (Based on Bitter Experience)

If you have already got hold of, found, stolen, produced or, in extreme cases, bought a new matrix, then we can proceed with the replacement. If not, then I would advise you to order a matrix already glued to the touch panel. As I understand it, they are distributed without any identification numbers.

Our tablet can be disassembled in the same way as most smartphones. The entire back cover simply slams shut with plastic latches, so we grow the nail and continue.

All iron is revealed to us in all its nakedness. Most of it is kept on bolts or sealed with tape. Disconnect the battery contacts and put it aside. Further alongside you can see one open train and one closed under a black Velcro. They must be turned off in order to remove the front panel later. We simply raise the first train, pull it towards ourselves. The second one is removed to the right, but before that you need to switch the mechanical keys up, it is convenient to do this with a knife blade.

If you look around the perimeter, you can see the bolts. We unscrew them. For convenience, you can count their number so that you know at the end how much you have lost. There are about 20 of them in total. Some are just as covered, like the one in the corner near the audio output.

We unscrewed everything and with a slight movement of a screwdriver we separate the motherboard and the front panel. The loop number 1 we need remains on the matrix. We disconnect it in the same way as we did with loop number 2 before.

Next, we need to remove the touch panel from the plastic frame. They are glued together with double-sided tape. At first I tried to use a soldering station hair dryer to heat the glue, but nothing worked. Then I remembered that I have a fireplace, one with the inscription “do not cover”. So I put the whole thing on top. The removal process is about the same as removing the back cover, only the latter does not burst like glass, but both processes take place with the help of the same nail specially prepared by us earlier.

The whole operation was a little harsh, and as a result I finished off the matrix completely.

If the old adhesive tape on the frame looks good, then put new glass on it, otherwise you will first have to restore the sticky surface.

We attach loop 1 to the new matrix, put the motherboard, battery, connect. We hold it all neatly with our hands, turn it on. Before twisting, you need to check if everything works well. We launch the device, open a black picture and evaluate the quality: are there any highlights and dead pixels?

If we are satisfied with the quality, then we can continue to collect. We tighten all the bolts, except for those that we lost, of course.It is worth noting the presence of two black bolts that are longer than the others. Both attach the speakers.

We screw in the screws in moderation, but "the Schaub did not crunch afterwards." That's it, you can slam the lid and cut off the grown nail.

And lastly - the most interesting thing: we remove the film.

As Americans say: “shit happens”, which means the inevitable happens =). I'm talking about the fact that there are such moments in life when you are walking down the street, playing your favorite game on your Nexus 7, and after a couple of minutes some “well-wisher” knocks it out of your hands, and that's all - to the screen. crashed. If, in addition, the tablet does not even respond to touch control, then the digitizer is also broken.

But you should not panic, because we live in the modern world and now everything is possible, even to buy gas boilers on the website. In this manual, we will tell you how to do this, but do not forget that all the risk and responsibility lies with you. If something goes wrong, these are your personal problems, and we are not responsible.

Several screwdrivers, and preferably at least one with a magnetic tip, will come in handy.

A plastic prykovyk, or what is better to call a tool that can be used to detach the tablet cover from the case.

Anti-static mat (optional) to protect the inside of the tablet from electrostatic discharge.

First, we need to carefully detach the back cover of the tablet from the case. To do this, we take a plastic tool, you can even use a fingernail, and begin to gradually squeeze the lid off the tablet body in a circle, starting from the top.Disconnect the power cable from the motherboard. This can be done with a small screwdriver. In turn, we press it on one and the second edge of the connector.Peel off the black adhesive tape that protects the cables connected to the LCD display. It is advisable not to tear off all of it: just free up enough space for work, and then use it again.Disconnect the LCD data cable and two more ribbon cables from the motherboard. To disconnect the data cable, slightly lift it up, but the adjacent ribbon cables are secured with clamps, which also need to be slightly pulled up.We unscrew 15 screws around the perimeter of the entire tablet, and here it is best to use a screwdriver with a magnetic tip.Now detach the LCD panel from the tablet body. This procedure should require a minimum of effort, just make sure that the data cable successfully passes through the hole in the tablet case and does not catch anything, because it can be easily damaged.At this point, you will need to heat the detached screen to separate the LCD panel from the plastic frame around it. To do this, you can use a hairdryer or, for example, leave the screen in the sun for 30 minutes. As soon as the screen has warmed up, begin to carefully detach it from the frame. The trick here is to try to keep the adhesive on the frame, not the display itself, as we'll need it to attach the new display. If the adhesive tape remains on the display, then you need to heat it up more, but if that doesn't work, then you will have to buy a new double-sided adhesive tape. Once you have detached the display from the frame, check if there are any pieces of glass left on it.Now put the new screen into the frame and check that the adhesive tape adheres well. Flip the display face down and attach the aluminum case / motherboard on top of it. Just remember to thread the data cable through the hole in the motherboard.As soon as the data cable is connected, we snap the ribbon cables with clamps. If you haven't thrown away the black adhesive tape, then glue it back over the cable and cables connected to the LCD display. We connect the power cable to the motherboard.Now we twist everything back with screws, and put on the back cover. We turn on the tablet, and we are surprised at our abilities =)As you can see, the procedure is quite simple, you just need to do everything carefully and slowly.If you have any problems, do not forget about the comments, then we will solve it together.
