Is it possible to repair the touch screen of a smartphone?

Previously, controlling a phone that had no buttons seemed like something out of science fiction. Now everything looks extremely simple. But do not forget that the sensor is a very complex device with a large number of important components that are not immune to breakdowns. Repairing without basic knowledge will be difficult, so you need to act with extreme caution. We don't want to break the phone, do we?

Before the repair procedure itself, you should independently or with the help of others establish the cause of the breakdown in order to prevent this from happening in the future. Failure can be caused by the following number of reasons:

Strong mechanical impact on the display.
Exposure to liquids or debris accumulation.
Working potential has been used up.
Software failure in the Android operating system.
Malfunction of the part itself.

For any of these cases, the restoration procedure will be very different from work in a specialized technical center.

The main nuances of screen repair at home

How to repair the touch screen on your phone at home? First, you need to clearly realize and understand that a mobile phone will not always be able to remain “alive” after repair. If you have already decided and have confidence in your actions, then you can safely get to work.

First you need to determine the exact cause of the breakdown. In order to do this, you can take the device for cheap diagnostics. If the type of breakdown is very familiar to you, then run to the store and purchase the necessary parts to carry out the sensor restoration procedure.

Assembling/disassembling and replacing parts with your own efforts has a number of certain advantages and disadvantages:

You may not be competent enough in matters of repair, but you must have a balanced desire.
You can perfectly understand all external processes, but not understand the internal ones.
Doing it yourself will void the warranty on the part.

If your intentions are still firm, then prepare your workplace, stock up on free time and the necessary tools.

Important! After repair, it is advisable to protect the phone from heavy loads.

How to fix a broken phone screen? Is all the work on the sensor effective? Let's get acquainted with recovery methods.

Repair

To carry out the work, you need to carefully take care of the workplace and acquire the necessary tools. Just follow the following manipulation instructions:

Take a small Phillips screwdriver and disassemble the phone case.

Important! If your mobile device model has an integrated display, then repair work at home is not possible. Take your smartphone to a specialist service center.

Using a soldering station with an amateur radio kit, strip all the contacts and press the contacts of the sensor itself to them. All that remains is to apply power and check the result.
If everything works out, then use a dielectric to secure the “legs” and assemble the body.
If you are unlucky, you will have to seek the help of a specialist.

Important! When working with a microcircuit, use clothing made of a material that will not accumulate static. You should also be grounded, observing all safety regulations.

How to fix the sensor on your phone if the problem is in the cable? The answer is provided below.

Repairing the cable

Again, you need to disassemble the devices, get a special alcohol-containing liquid and wipe both the connector and the cable with it.
The most ordinary school rubber band will help you with “repairs”. We take it and clean the contacts of the cable so that they shine.
But it is not always possible to get rid of the problem. In this case, take a thin rubber band and install it in the place where the cable and connector are connected. These measures will help improve communication.

Important! Often the procedure for repairing and replacing sensors looks very monotonous, no matter what the cause of the defect. The manipulations themselves are not particularly complicated and do not require any special technical knowledge. The most important thing is to be patient and be extremely attentive to all the actions you take. If you still have extra funds, then it is better not to take the initiative into your own hands and go to the nearest service center, where a specialist can handle it in a time or two.

Moisture has entered

For many users, sensor breakdowns are caused by exposure to moisture and there is a need to dry the mobile device. To do this you need to do the following:

Immediately remove the battery to protect yourself from the consequences of electrolysis. Electrolysis can “destroy” the oxidizing contacts, making the battery unusable.
Now disassemble the device body using watch screwdrivers, wipe the board with a special alcohol base.
Now dry the phone thoroughly and return all components to their places.

Your question:

How to fix the display on your phone?

It would seem that if the screen of a cell phone fails, then there is only one way out - throw away the old phone and buy a new one. However, there is no need to rush to waste money, because a damaged screen can be replaced yourself. This is actually not as difficult as it might seem at first glance.

Initially, you should determine whether the display is broken. In case of a distorted image or several dead pixels, you must contact a service center, whose specialists will be able to quickly eliminate these display malfunctions using special equipment. Well, if the image is completely absent, “freezes” or there is no response to touches in touch phones, in these cases, most likely, replacing the display is inevitable.

Turn off your phone completely by holding down the power button for a few seconds until the phone turns off. Remove the back cover and remove the battery from the phone.

Using a Phillips screwdriver, unscrew all the screws located under the battery, remove the back panel of the mobile phone and remove its side buttons. This way you have access to your phone's circuit board.

You will see a small cable that comes from the phone board and can be located at the top or bottom of it. Then, you need to remove the board from the phone, under which the reverse side of the LCD screen will be located.

Remove the screws that secure the LCD screen to the front of the phone. Remove the old LCD screen and replace it with the new one. Connect the cable to the screen and screw in all the mounting screws in reverse order.

Place the board in its original place and connect the cable. Secure the board with the mounting screws. Don't forget to insert the side buttons. After that, install and secure the back panel of the phone with screws.

Install the battery and close the back cover of the phone. This completes the screen replacement process. Turn on your cell phone and test the new LCD screen.

Instructions: how to fix the touch screen yourself

So, let’s solve the question of how to fix the touch screen. We start work by cleaning the workplace. You need to take an empty container to collect bolts that have a habit of getting lost. You will then need to separate the sides from the phone using a hex screwdriver. You will need to unscrew the bolts from the bottom of the back cover, as well as the side bolts. Two bolts in the compartment where the battery is located are also removed. This is done carefully, otherwise it will fail altogether. Only then can you remove the top cover. After disconnecting the panel connector, use a Phillips screwdriver to unscrew all the screws from the top. There is also a headphone slot. There is a microphone under this connector. By releasing this connector, you can free the screen board from the case. Using a stationery eraser, carefully clean the contacts of the cable, after which they will shine. Then you need to turn the screen over and connect it to the board. Now you can turn on the system. Using tape, the battery is secured to the board; remove the lock for this design to work. On the panel, activate the Power option.

Troubleshooting to fix the touch screen

You need to press on the connection point and move your finger or stylus across the panel. If the touch screen works, then you can carry out the repair yourself. A very thin tape from the eraser is cut out - no more than 1 mm, and glued with glue to the junction of the screen and the cable. After assembling the device, it should work. When assembling the structure, you need to bring the entire system to its original position and do not forget to remove the tape.

#5 Local repair shop

Keep in mind that a private repairman may not use original parts. Apple no longer voids the warranty if the iPhone is repaired by third-party manufacturers or private repairmen. This is good news, but if there is any damage to the iPhone from a third-party repair, you may get your warranty voided. If your phone is less than a year old, it may be worth looking towards an official repair, as for local repair shops. Find out if they provide any guarantee on their work. Many provide a short warranty period, a couple of months or even less.

In any case, if cracks appear on the screen of your smartphone, you must first assess how extensive the damage is. You may be able to live with minor display cracks that don't interfere too much with normal use of the phone. But if the screen is cracked well, the cracks are deep and occupy a large area, then you should probably immediately contact a workshop or take independent measures to repair the phone.

If the colors on the screen are abnormal or some pixels are no longer visible, the damage is much more than a cracked glass top layer of the smartphone screen. This means that the damage has affected the LCD panel. In this case, as a rule, phone repair will cost at least 50% of the cost of a new smartphone of your model! If the phone is not associated with any memories, then it is cheaper to sell it for spare parts and buy a new phone.
