Samsung phone has a black screen what to do
Proper handling of the TV is the key to its long-term service.!
Often equipment breaks down due to improper operation.
Unscrupulous attitude to the appearance of minor malfunctions, mechanical stress, penetration of moisture into the body. all this leads to wear of the components, as a result of which malfunctions appear.
One of the most vulnerable spots in modern TVs is the inverter. This part often fails. An inverter is an expensive part, so a specialist will most often recommend repairing it rather than changing it. This problem, for which the picture is missing, is typical for TVs of LG and Samsung models.
Why is there a black screen on the TV, but the sound remains?
You are faced with such a problem on TV: the TV screen is black, but there is sound. Naturally, due to this malfunction, viewing the programs is not possible. In this article, we’ll show you what to do about this problem. What caused the picture to disappear? Let’s look at the internal and external causes of the problem.
- To understand what went wrong, the first thing: we look at the equipment. If the equipment is completely new, this malfunction may appear due to the manufacturer’s defect.
- If the device has served you for several years, there is a possibility that the batteries or backlights are out of order.
Don’t be discouraged if you just see a black screen when you turn on the TV.
There is a possibility that the solution to the problem is very close:
- Antenna cable (cord);
- Distribution box;
- An external antenna located on the roof is the most vulnerable element in this problem.
Inspect these items, especially the plug. Basically, it is connected from the back to a special connector (socket).
First you need to pull it out of the connector and insert it back. There is a possibility that due to poor contact, the signal coming through the plug is weak. This could be one of the sources of image fading.
Next, you need to connect a second TV (of course, a working one) to the antenna wire in order to check the signal quality.
If, after connecting, a poor-quality signal began to arrive or there is simply no image, then most likely the problem is either in the external antenna or in the antenna cable.
If there is a problem with the external antenna, then it remains only to call the organization responsible for its maintenance.
Why does a black screen appear on TV and sound works
Try to find out if your TV has a mute function. This is true for newer LCD / LED TVs such as:
- Philips (Philips);
- Toshiba (Toshiba);
- Sony (Sony);
- LG (LG);
- Samsung (Samsung).
Certain TVs have the ability to turn off the picture: this function allows you to listen to the sound of the TV or DVD player when the picture is turned off on the screen Make sure not to enable this function.
But if we exclude all factors from the outside, then only the problem remains at the hardware level. Let’s take a look at what’s the matter.
A common cause of malfunction of new TVs, due to which the image disappears when there is sound, is the failure of lamps or screen backlight LEDs.
The easiest way to determine whether the problem is in the backlight or not is: take any light source (lamp, hand-held flashlight, or even a flashlight on your phone) and, with the TV turned on, bring the light source to the screen.
If you see that the image is there, but it is very difficult to see, then your lamps or LED strip are out of order. Of course, there is a possibility that the color module, power supply, frame and line scan unit, tuner or matrix are out of order.
If you are not an expert in this matter, it is quite difficult to replace or repair the listed parts, therefore, this work should be carried out only by a TV repair specialist.
What is the reason for the disappearance of the image on the TV screen connected via HDMI?
Let’s just superficially touch on the connection via HDMI of a computer to a TV. In rare cases, with this connection, the image may disappear quite often. The first thing to do is test the HDMI cable itself. Also check if hibernation is running on your computer.
The sound can also be played, but the picture will never be. Basically, everyone can cope with the HDMI cable connection, and this is not a serious problem if you have a whole and working HDMI cable. But this issue also has its own pitfalls that the user may encounter.
So what to do. If you do not have an image when connecting, check the cable for kinks, bends, breaks, if there is such damage, you need to replace the HDMI cable.
You also need to check the settings and make sure that the computer has not entered sleep mode. Another option is connector failure. In this case, you need to refer the technician for repair to specialists.
These are the main reasons due to which, when the TV is connected via HDMI, the image is not displayed.
