What to do if iPhone 4 s. If the buttons don't work

If the screen of an iPhone does not work, not all owners know what to do, and yet the question is very, very relevant: the cost of the display is high, so replacing it out of ignorance can lead to unnecessary expenses. To avoid this, it is important to know two things: the causes and ways to fix the problem without harming the phone.

Screen stopped working on iPhone 4

Before rushing around in a panic and looking for advice wherever possible, check if your device is frozen. Yes, Apple devices They hardly freeze, so this phenomenon is mistaken for a breakdown. A broken screen in this case can be easily corrected by rebooting (holding the power button and sleep/home). If this helps, but is repeated frequently, contact service immediately - the screen is fine, but the system itself or the components are “naughty” - they need to be repaired.

If rebooting does not help or the apple symbol does not appear, proceed to the next step. Another reason why the screen on the iPhone 4 does not work may be its Chinese origin: non-original equipment breaks down very quickly, not to mention the fact that its repair exceeds the cost of the product itself several times. The decision to buy an iPhone secondhand is quite dubious. Think about it, do you need it? Yes, you will save several thousand rubles, but then you will go broke on replacements.

Screen on iPhone 4s does not work after flooding

Having “bought” your device, you risk completely ruining it, so do it as quickly as possible the following actions:

Turn off your phone;
Disconnect the battery (You will need a screwdriver for the small bolts, it is screwed on);
Wipe away any visible water;
Place the iPhone in a container with rice and leave it for a day.

After this, the device may turn on, but it is better not to risk it and contact service. Instead of rice, you can use a hair dryer or a special case, but in the case of a hair dryer there is a risk of damaging the insides and completely “killing” the device, and in the second case the price of the case may be higher than the price of repairs from honest craftsmen.

iPhone 4 screen does not work: what to do

Check battery charge before disassembly

The first thing to start diagnosing is checking the charge level. Oddly enough, one of the reasons people turn to Apple services is simple forgetfulness: a completely discharged phone may not turn on even when running on a charger, which people who are especially prone to panic perceive as a breakdown.

If everything is fine with charging, inspect the iPhone. The screen does not show, but everything else works - you should think again whether you or anyone else has ever flooded the device, because the remaining moisture is insidious and slowly harms the entire device, even if it worked before. Were there any such cases? Well, you are a very careful user, so the reason why the iPhone screen has stopped working, there is sound, and calls are still being made is either a breakdown of the screen as a whole, or a loose cable.

Having experience in assembling and disassembling complex electronic devices, you can disassemble your iPhone yourself and check the reliability of the cable fastening, but remember: if the phone has a warranty, you should not do this, otherwise any service will revoke the warranty due to opening.

There is no guarantee - no worries, you can check. If the cable looks correct, it is better to take the iPhone for examination. Advice for owners of kinescope TVs and screens (if there are any left): do not place the device on them; the iPhone 4c screen does not work after lying for a long time. Either charging with a reboot or service helps. The influence of the kinescope on iPhone screen palpable.

The iPhone works, but the screen does not light up

Often, by “does not light,” users mean an insufficient level of backlight, which confuses the craftsmen. If your screen is just dimly lit, but the picture on it is clear and the device’s response is good, increase the brightness in the settings - it will help 100% if the firmware is original and correct. A non-working item for changing the backlight may cause an error during the update, this is corrected by the firmware, which is better to do in the service.

If you don’t want to contact service for such a small thing, try resetting the settings to factory settings, it may also help. Don’t get carried away with unauthorized flashing: the same JailBreaks are capable of introducing malicious code into the system, causing individual components of the iPhone to function incorrectly.

Choosing a service

Quality service is the key to iPhone performance

“The iPhone works, but the screen is black? Our masters know what to do!” A similar statement is found in various forms in contextual advertising, and in paper advertisements, the essence is the same: to lure you as a client. Do not be fooled by discounts and free diagnostics: a licensed service charges money for diagnostics, but then deducts its amount from the cost of the service. What to pay attention to when visiting:

Availability of a service center in the list of official Apple services. It can be found in the community and on the website;
Reviews. You are not the first one whose iPhone screen does not work, which means that a similar problem has already been addressed, and this can be described in the reviews. It is important to check reviews not on the official website, but, for example, on in social networks, since reviews on the site in 95% of cases are written by the owners of the service;
Condition of the premises. It is better not to go into basements where mushrooms grow on the walls;
Price. Professional service centers are unlikely to undertake replacing the display for 500 rubles. Low price should be alarming.

By the way, services that promise “only original spare parts” are often disingenuous: original spare parts Apple does not, there are high-quality Chinese analogues. The paradox is that phones are repaired with the same parts from which high-quality replicas are assembled. After handing over the device, do not forget to take the equipment acceptance certificate for repair, which should indicate the ID of your iPhone.

If the iPhone 4s does not turn on and does not show signs of life, do not panic.

Use our article to find the causes of the breakdown.

Reason #1. Out of charge

Very often, users encounter this trivial problem when the phone does not turn on, and in fact it just needs to be charged.

In this case, connect the device to the adapter and hold it for about 15 minutes; the charging icon should appear on the screen.

What to do if the device does not charge?

If the iPhone 4s was completely discharged and after 15 minutes of charging, the “lightning” and “socket” icons are lit on the screen, you still need to keep the phone on the charger.

There are often cases when a fully charged smartphone does not charge or turn on for no apparent reason.

This problem associated with rare iPhone 4s updates.

The solution to the problem is simultaneous retention home key and power for 15-20 seconds until an apple appears on the screen.

Reason #2. Faulty charger or battery

If after connecting the adapter and waiting for some time the device does not charge, then the problem may be a broken plug or cable charger.

Advice! Try connecting the charger not to the outlet, but to the computer; if after that the charging icon does not light up on the screen, then the problem is with the adapter.

May cause damage improper operation charging in the house or car.

But if the screen does not light up and there is no charging, then it may be a faulty battery.

As with any phone, the battery can fail. This could be either a manufacturing defect or the fault of the iPhone owner.

Advice! If there is a manufacturing defect, it is better to return the device to the store.

If you've had your iPhone 4s for several years, don't be surprised if it doesn't hold a charge well - this is normal wear and tear.

But if new smartphone constantly requires recharging, then you should think about changing the battery or at least purchasing an external one.

Reason #3. Power controller failure

There can be three reasons why the power controller fails:

Poor quality or faulty analogues of the original charger.

Advice! It’s better to buy an original charger right away than to spend a lot of money on iPhone repairs later.

Voltage surges.

Advice! Do not charge your iPhone on a train or in places where the voltage is alternating.

Dirt and dust get into the charging connector.

Reason #4. System failure

Often the smartphone does not turn on due to a system failure. The main problems may be:

incorrect OS update;

What to do in such a situation? Try rebooting your iPhone 4s by pressing Power buttons and Home.

If after a reboot no sound signals, the apple icon is not lit, then connect the iPhone to the computer and open iTunes.

But the device still won't turn on? Then you need to reflash your smartphone.

If you haven’t done anything, haven’t updated, haven’t downloaded games, don’t understand how to reflash your phone, then it’s better to use the services of a service center.

Reason #5. Problems with phone firmware

Why does the device show the apple logo but does not start the system? Most likely, an error occurred while flashing the phone's firmware.

Try to do forced reboot via the Power and Home buttons. But, if the reboot fails, try restoring it.

Restoring differs from updating in that the data will be deleted, factory settings will be installed, and when updating, all data will be saved.

Connect the device to the computer and turn on iTunes.

Select our device and click on the shift button, and click restore.

You must specify the path to the downloaded IPSW file, which is the firmware. Click “open” - the restoration has begun.

Reason #6. Damage due to moisture ingress

What to do if water gets on your smartphone? It is not necessary for the phone to be submerged, but a few drops are enough to disable the device.

In this case, just remove the battery from the phone and let it dry.

Advice! If you decide to disassemble the phone yourself and disconnect the battery. Then during reassembly, before inserting the SIM card, install right time, otherwise after assembly there will be glitches in the communication module in the future .

But if after these manipulations the iPhone 4s does not turn on, then we advise you to take it to service center.

One of the most common problems with the most popular Apple device called iPhone is charging.

Sometimes this problem occurs in the first year of use, but most often in the second or third.

We will try to figure out what to do if your iPhone is not charging. The logic will be like this - I name the reason that there may be and possible solutions.

Why won't my iPhone 4, 4S, 5, 5S, SE, 6, 6S, 7, 8, X, 10 charge?

Just out of interest, I did a little searching to see what some of the sites offered. And to be honest, sometimes there are options that are better not to be implemented by the average user.

Therefore, let's be realistic and I will tell you about the most common ones that you can fix yourself and more.

Absolutely any thing becomes dirty if you don’t clean it periodically. The same goes for the charging port.

Our iPhone is always with us and no matter where we are, so it is simply unrealistic to avoid dirt and moisture getting on its components.

So if you try to charge your device, but it does it every time or when you move the connector, then check that everything is in order there.

We take a toothpick and a flashlight (or look for a well-lit place) and carefully clean the connector. You will be surprised how many interesting things you can dig up from there.

The iPhone charger components are not known for their reliability, especially the cables.

The wire often starts to peel off and eventually just stops working. It all has to do with the fact that they are made from materials that are safe for the environment.

Therefore, your task is to check your cable and unit with another device, and also check your iPhone with a properly working charger.

This way you can understand what exactly the problem is. And you don't have to buy expensive ones Apple accessories. After all, there are other manufacturers who are certified and cheaper.

People really like to save money, so they buy very cheap cables for iPhone charging. Realizing that this is not the most the best option developments, people still do it.

I won’t argue, sometimes there are very high-quality products and everything charges normally and without incident.

But there are times when the phone does not charge at all using such a cable, discharges, or can damage your device.

If, when you connect such a cable, you see the message “This accessory may not be supported,” then it’s time to think about buying a new one.

A lot of manufacturers like Belkin make very good accessories that are cheaper and last much longer.

Are you trying to charge from a USB port?

You don’t always have an outlet at hand and sometimes you just want to take your iPhone and charge it a little with desktop computer or laptop.

Most often, everything happens successfully and your device charges. The process is of course slow, because the current is not so large, but the process is going on and everything is fine.

Not all ports have required characteristics to allow your device to charge and that's why sometimes you don't see any response. Try all ports, maybe another one will work.

In general, the problem is not the cable or the iPhone. Just try to do it from an outlet or Power Bank.

Other points

In all other cases, it is best to contact a service center and not do anything on your own.

Such cases include the following options:

iPhone turned off and won't charge;
shows that charging in progress, but actually not;
dropped the phone and then problems started;
other.

The last ray of hope may be a simple reboot iPhone. Either turn it off and on, or, depending on the model, press two different keys, thereby rebooting the gadget and then trying to charge it.

It doesn’t matter what iPhone you have (4, 4S, 5, 5S, SE, 6, 6S, 7, 8, X, 10). All models are made according to the same principle; there are no separate approaches for each. So by following these instructions, you will succeed.

The first part of the article summarizes possible software and hardware causes of failure. The second part of the article talks more specifically about all the common reasons why the device does not work.
