A black screen on Samsung brand TVs occurs frequently. In another way, it is also called the “screen of death”. Despite the frightening name, the problem can be fixed by the owner himself. This does not require special tools or serious skills.
Why does the black screen of death appear on Samsung TVs?
The appearance of a “screen of death” instead of an image is a common problem that many owners of Samsung equipment face. The easiest way to fix the problem is to reset the TV by turning it off for 60 seconds. After that, you need to press and hold the power key for 30 seconds, and after a minute turn on the TV again. It should work like before.
In 90% of cases, this solution will help get rid of the black screen. But there are still 10%, which include malfunctions associated with the breakdown of internal elements of equipment. But, before proceeding directly to the repair, it is necessary to check the performance of the main elements.
Disconnecting the TV from the power
Powering the TV on and off is the simplest action to help deal with the “screen of death”. It is important to make sure that there is a good cable connection between the external source and the device. After turning off the TV, the user must check all connections, remove the cables from the socket and reinsert them. The power supply unit and cable must be in good condition.
When reconnecting all cables, it’s worth double-checking that they are plugged into the correct jacks, especially if you’re using an RCA cable.
Checking connected devices and using other input sources
If turning off the power does not help, and the problem persists, then you need to check the connected devices. Sometimes a sudden failure occurs due to tangled cables that do not allow the connectors to connect correctly. The easiest way in this case is to disconnect all cables, especially devices that work via HDMI.
The fact is that HDMI streaming devices are very popular with modern users. At the same time, the number of calls about the sharp appearance of a black screen is growing. The problem occurs due to a bad connection.
In some cases, it will be more correct to switch the cable from one HDMI socket to the second one. Samsung TVs often have up to 4 identical connectors. If this does not help, then it makes sense to completely replace the cable with a new one.
TV backlight test
Sometimes the TV stops displaying the picture during broadcasting, while the power indicator lights up green, but the sound continues to sound from the speakers. This problem is due to a malfunction of the LED strips on the backlight.
To check its performance, you must perform the following steps:
- Make sure the TV is turned on and take a flashlight, or turn it on on your smartphone.
- Direct the light at a distance of 5-10 cm from the screen.
- If the image appears in the place where the light was directed, then the backlight is not working.
Unfortunately, backlight repairs are expensive. If possible, it is better to give the TV for repair through a warranty service.
Checking the remote control
Sometimes there are situations when people watching TV accidentally sit on the remote control and do not notice it. It is possible that random options or broken buttons will be activated after this. This is often the problem with the appearance of a black screen.
Turn off the “sleep timer”
Modern televisions are equipped with “sleep timers”. They force the device to turn off automatically if there is no action from the user for several hours. The system considers that the person fell asleep or left the house, forgetting to turn off the TV. Many owners of “smart” devices are not even aware of this feature.
To turn it off, you need to enter the “Menu Settings”, go to the “Time” section and find the “Sleep Timer” option. Here you can turn off the function and not worry that the TV turns off automatically.
The most common types of Samsung TV problems
Do-it-yourself repairs can be a time-consuming task for people who do not have certain skills. The average user can easily troubleshoot software glitches and misconnected cables.
The most common type of malfunction is a broken backlight. The absence of an image provokes cathode burnout. Masters simply change broken parts for new ones, unscrewing the bolts and the board. The matrix, as a rule, remains in place, so you should not worry about getting dust into it.
The second reason for screen failure, often found in people with Samsung TVs, is the burnout of the power board. This element has different shapes, depending on the size of the TV screen. Large devices have a chassis-shaped circuit board, while compact devices have a box-shaped circuit board.
What breakdowns can be repaired by yourself?
If the Samsung TV lost the image, and instead a “screen of death” appeared, this does not mean a technical problem at all. Some situations are solved with simple actions. Let’s list them:
- Replace the damaged cable with a new one.
- Increase the TV volume “to the maximum”.
- Check the antenna cable for damage to the socket.
- Reset the device to factory settings.
The above recommendations will only be useful if the TV is turned on and has sound.
When is it necessary to contact a specialist?
If you can’t deal with the problem on your own, you will have to seek professional help. Users can contact Samsung Warranty Service or private repairers. The cost of repairs depends on the severity of the damage.
You can not carry out self-diagnosis without having special skills for this. Wrong actions will provoke the emergence of new problems, which will subsequently cost the owner dearly.
