The following software reason why the screen has stopped turning on in your Samsung phone can be attributed to a lack of RAM for processing a request by pressing the unlock button (Power, Home) or during a call. Perhaps you noticed that the smartphone began to work more slowly shortly before the breakdown?

If this is the case and the phone works, but the screen does not turn on, then you need to restart it. You can wait until the battery is completely discharged, or remove the battery yourself for a few seconds.

At the time of switching on, pay attention to the initial screen: is there a Samsung and / or Android logo.

Hardware reasons

Perhaps burned out, dirty? The contact group under the case could burn out and no damage was visible. This can happen as a result of a power surge during charging from the outlet.

To end the conversation about the lack of charging, which is the reason why the screen of your Samung phone does not work, you must also mention the battery itself. See if he is swollen or there is no raid on the contact group. If there is. replace with a new one.

Of course, the most popular reason for a phone’s screen not working is physical damage: it hit a hard surface, or the phone itself was hit with something heavy. Even if there is no visible damage, the internal components may fail due to microcracks on the board or loops.

If your Samsung works, but the screen does not want to turn on / off during a call. the problem is the proximity sensor, which is triggered when your cheek / ear approaches the screen and extinguishes it so that you do not accidentally press a button during a call. The same sensor turns on the screen when you remove the screen from your ear. He himself could have failed, or his cable, which connects to the main board. You will need to disassemble the smartphone.

The remaining causes are quite rare and diagnosis is required to identify them. Therefore, contact a service center to determine the cause and eliminate it.
