This notebook is a friend. Out of trust in me, toss the computer for me to repair. (Another important reason is that there is no need to pay labor fees, go to Dell after-sales or computer shop repairs, the cost is about 400 to 800. Let me repair The cost is only 200 for the screen! But you need to bear the risk of the computer being accidentally repaired by me.)
The main task: dismantling and trying to repair the old screen and replace the new screen!
The article is divided into three sections:
First, who exactly is the problem of testing: video card OR screen OR system?
It is determined that the screen hardware problem: purchase a new screen (a universal treasure), plus a memory.
N5110 screen _ Taobao search search: own computer brand model + LCD screen s.taobao.com direct link Prices range from 160-300, 160 are all used, 300 is the so-called A+ new screen.
Specifically in which to buy will not say, in fact, are similar, are not pure original screen.
In the third paragraph afterwards, I will elaborate on where the screen pits are!
Second, entertainment dismantling the old screen
Third, the screen replacement upgrade! (Why upgrade, because the resolution of the old screen is 1024*768, and the new screen resolution is 1366*768)
Fourth, do the system + win10 whitewash
# This is a borderless ultra-thin streaking notebook ↑↑↑↑↑ #
Use exclusion to detect what is causing the problem.
First boot into the bios, the green screen - the probability of the problem on the screen is 80% (after all, the bios does not involve graphics cards and systems)
Forget about bios
However, the landlord did not give up, smoothly re-do a system for him, installed a new graphics driver, and then eggs ... ...
Finally in order to determine the problem is really a screen, try connecting to the outside world
HDMI: This computer's HDMI interface is bad, so only use the VGA connector.
VGA connector: can only use old monitors that have been eliminated
The display is normal, so 99% is a problem with the display.
Second, the complete dismantling of the screenSince this is an old computer, dismantling is still relatively simple. The third paragraph will show how to install it in detail.
Start with the keyboard
Knock on the front panel
Unscrew the screw on the display base and separate the home
Since they are all dismantled, they can easily clear the ash and change it.
In order to facilitate the next test, the power switch is separately connected to the main board, which is convenient for the naked boot to test.
First to a schematic
Simple understanding of the two parts, LCD screen + backlight
let's go
After removing the front and rear shells of the display, put it naked and try it out.
Workmanship is better than the screen I later bought on Taobao
Start to split screen
A total of two screws on the left and right
The remaining buckle, a little bit open
Backplane power connector
Pull down the backlight power supply, the next step you can pull out the LCD panel
Now the LCD panel and backlight are detached
This looks like the LCD panel is opaque and actually transparent.
Then plug the host up
The bottom right corner is not a broken screen. It's really just a pattern.....
The backlight can read the book in the middle of the night in a bed.
The effect is good
However, we can only see single-sided printing, and double-sided packaging will be indiscriminate.
Retro projector ⇩⇩⇩
Unfortunately, the room is too bright, there is no projection effect
Tossing for a long time, you can see that the old screen should be the motherboard is broken, not the line problem, so, with my maintenance level can only change the screen, and the screen is not expensive.
Third, change the new screen! 1, the screen on Taobao can be simply divided into:
Miscellaneous cards include: AUO, Chi Mei, BOE, LG, etc.
(15.6 inch / resolution 1366*768 /)
The above table is almost the cheapest price Taobao, if you need to change the screen can do the next reference
A+ is a screen with no bad spots
A- is the bad point in 3 following screens
I bought the so-called A+samsung screen, 220, it is original brand new, but look at the picture.
The label was obviously torn off
The difference between the old original screen and the original label
Why is it not a pure original screen?
1, the label is slightly false and some surfaces are obviously passive
2, above mentioned the original screen work, obviously better than this
3, look at this magical backlight wiring
TMD is actually welded directly, and the baby is forced to...
This screen does not have a bad point, and the color display is also good, I will not compare, 220 the absolute value of the price.
The screen should be Samsung, there is no scratch, it should not be second-hand, the backlight board is installed by Taobao manufacturers, so overall it is OK! The only problem is not knowing how long it will take.
Another reason for buying Samsung is that the Samsung screen will be relatively stable, but I hope it will take two to three years!
After the screen reaches the hand, try connecting directly to the host
# Buy screen does not contain screen cable! ! ! (I almost threw the old cable before the new screen arrived) #
2, the installation of the screen1 fixed screen
Unplug the screen
Screen and bracket
Since the screen was delivered for three days, I divided the screws into two bags, a pack of screens, and a pack of hosts.
Four small screw fixing brackets, large screw fixing brackets and screen
Small screws fixed screen
Fixed
Fix the rod and try it on the host
2 plug in the cable
The cable socket was originally covered with a plastic film, and it was too hard for me to check it back.
Insulation glue instead of it
Finish the head of the cable and wrap it around the bracket to facilitate installation
3 Mount the screen on the housing
The shell is a whole wifi antenna, the notebook is basically the same
Intel network card
Four corners up and down, 8 large screws
After screwing it on, it was found that the camera card was forgotten, FUCK
The NIC's cable also goes around the bracket socket
Front cover
Plug in the host
4 screen connection host
This is the first security, it's not up to the name.
Then plug in the screen
Plug in the screen cable
5 host installation
Mainframe screws, only two small screws
This piece of screw line block, there is a hole actually can not be screwed, did not send the time
Panel
Keyboard, Touchpad, Shortcut Interface
The screws on the back are screwed on
Finished! ! !
Win10's system personally feels good, two years of continuous improvement, and now it is very good.
As for why he is safe and win10, mainly I am lazy!
Win10 will automatically install all the drivers, very peace of mind, I have obsessive-compulsive disorder, do not like to use what drives the wizard to drive life. It will come with a lot of software, not pure.
Win10 in order to promote, do anything!
Said before win7, win8 free upgrade within a year, the results are still free upgrades, and pirated whitewash! ! !
1, first install any version of win7 (I chose the official pure version, after the installation shows a trial of 30 days)
2, use the activation software: I recommend "pony win7 activation tool" success rate of almost 99%
Or win7/8/10 Activation, this is a set, can easily activate office
What drivers will not be safe after activation?
3, on the Microsoft official website win10 download installation media (upgrade win10 software) MediaCreationTool.exe
Download Windows 10 Direct Links Follow the instructions to install
4, choose not to retain personal data, settings (because you have already redone the system, there is nothing to keep)
5, networking, let win10 download updates and drivers
6, to c drive - right click - Properties - Disk Cleanup - Clean System Files - (Update the updated files and win7 files are deleted, nearly 10G å‘)
Of course, you can directly press win10 mirror version, direct piracy, and then activate, but it seems that it is still pirated, there will be a certain probability of problems, the system is unstable!
And if you directly install win10 iso, it seems that you need to enter the serial number, I forgot
Perfect whitewash! ! !
In fact, genuine piracy is just as useful, but it's not better to have a genuine copy.
Overall, this screen change is still relatively perfect
Value friends with hands-on ability to buy screens in Taobao, to carefully pick a seller, chat with the family.
And the arrival must be in front of the courier face unpacking! Generally have insurance! If it is broken, reject it directly!
The price of official aftermarket repairs is generally quite expensive.
If they are looking for a repair shop, their screens are also uneven, so it is better for them to change screens.
