TV Writes No Signal Check Connection

Consider the essence of the speaker in system diagnostics

Any modern motherboard is equipped with a built-in warning and diagnostic system. This system, before loading the operating system, checks the health of all major components that are connected to the motherboard. In the event of a malfunction, using the speaker, the system beeps. The number of signals supplied (squeaks) corresponds to certain faults.

In order to determine the malfunction of your computer, you need to know:

  • BIOS version of the motherboard (written in the motherboard instructions);
  • a list of signals of all faults (written in the instructions of the motherboard).

If this list of signals is absent in the instructions, then you need to look at the reference sites or on the manufacturer’s website for this motherboard.

First act

Disconnect all components from the motherboard. In this case, you should leave the processor, power supply and indicator buttons of the system unit connected. After these steps, turn on the computer. The speaker should beep, which warns of the lack of RAM. Next, you need to check this signal with the list. If the signal differs from the required signal, the malfunction may lie in the motherboard connectors for RAM. Also, the problem may be in the system bus, or the RAM controller. If everything is correct, you need to go to the second step.

If there is no signal on the monitor. Troubleshooting instructions.

TV Writes No Signal Check Connection

What to do if your monitor gives a message “No signal, check cable”. Step-by-step instructions for diagnosing and eliminating this malfunction of a personal computer, monitor and connecting cables.

Actions in case of signal disappearance on the monitor

Nowadays, most people have their own personal computer at home or at work. Along with its positive characteristics, this smart unit sometimes gives various malfunctions, including also serious breakdowns. The fact is that a computer is a rather complex electronic system. Therefore, it is often difficult or impossible for people who do not understand this industry to understand why there was any breakdown in the computer. One of such breakdowns may be the disappearance of the signal on the monitor. This breakdown can be absolutely trivial, or it can affect the replacement of expensive and important components of the system unit. Consider this case.

During the next boot or restart of your computer, for some unknown reason, your monitor goes blank. After multiple reboots, you see that the monitor does not light up, and the inscription “No signal, check the cable” appears in the center of the monitor.

The very first step is to stop panicking. In this case, it is necessary to find the cause of this breakdown or defect. In the event that there is no signal on the monitor, you must carefully check the condition of the power cables, as well as the cable connecting the monitor to the connector of the system unit. In this case, there may be different options. Maybe for some reason the plug does not mate with the connector. In case of a skewed position of the plug or its absence in the connector, you must carefully connect it to the desired connector. If this was the problem, then the screen should blink, switching to power saving mode. Next, the indicator on the monitor should light up in green, and then orange. After the lights come on, you need to restart your computer. After pressing reboot, after a few seconds the screen should display a picture of the system boot.

If there is no response from the monitor, proceed to the next step. To do this, you need to have a speaker system unit. The speaker is a small speaker or a small buzzer, which, together with the indicators and buttons of the case, is connected to the motherboard.

You need a speaker to diagnose the internal components that are in the system unit. If you haven’t changed your BIOS settings then your buzzer or speaker should be enabled by default. Otherwise, you need to reconfigure the BIOS in order for the speaker to be turned on.

Consider the verification actions using the speaker

Second action

You need to connect the RAM to the motherboard. Then you need to turn on the computer. The speaker should make a sound, indicating that the card is not connected. In the event of a signal about a malfunction of the RAM, it is necessary to diagnose it. The reasons for RAM problems can be a defect in its strips, a defect in the operation of the RAM controller located in the motherboard, as well as a breakdown of connectors. In this case, the best option would be to replace the motherboard. The fact is that this repair will not guarantee the absence of subsequent breakdowns and is a rather expensive pleasure. If the signal matches the list, proceed to the transition to the third action.

Third action

You need to connect the card. Then we turn on the computer. The computer signals that the card is not connected. In this case, it is necessary to check the card connector. The check is carried out for traces of short circuit or oxidation. Oxidation traces can be cleaned, but with traces of closure, the connector can be considered inoperative. In this case, it must be soldered or the motherboard must be replaced. If the connector is clean and functional, you need to check the card contacts. In case of oxidation of the contacts, it is necessary to lightly clean them with a stationery eraser so as not to damage the coating. You should also look at the components of the card for burnout. Replacement of a damaged small radio element of the card can take place, but failure of the microchip means that it is necessary to change the card.

If the speaker gives a signal “problem with the south bridge”, then you need to contact the service center.

If there are no signals, check the connection connectors on the card and on the monitor. To do this, you need to take an additional monitor and card. In this case, they should work. To check the card connectors, you need to put in a working card. To check the connectors on the monitor, you need to connect a working monitor to the system unit.

In addition to the listed problems, there may be wire problems. They could be damaged by your pets, small children, and you yourself could accidentally hit and damage the wiring. In this case, it is necessary to replace the monitor connection cable.

If after all the checks carried out there is no signal on the monitor, then the power supply may fail. The fact is that during a reboot, microcircuits occur in the power supply. It is possible that some radioelements could not survive the microcircuit data. As a result, the power supply stopped producing the necessary power to operate the card. As a result, the card could stop working. In this case, you can disassemble the system unit and look at it for the presence of carbon deposits, swollen capacitors. Most often this happens with old power supplies.

No image via HDMI on TV or monitor: what to do and how to be

Hello! Today we will talk about a very strange but interesting problem when you connect a laptop or computer to the TV using an HDMI cable, and you see the inscription “No signal” on the screen. The problem is not new and has several solutions. Most often, a connection error occurs either due to hardware problems: for example, when the cable SIMply leaves in some place.

In other cases, this usually indicates problems with the computer or laptop, and in particular with device drivers. We’ll talk about all this at the very beginning. But first, he will try again to output the signal and images to the TV.

  • Correct connection
  • No picture
  • Screen frequency changes
  • Updating drivers
  • No sound

Correct connection

The best way to fix something is to do it again, but in the right way. Therefore, let’s try to “connect” again, perhaps you are just doing something wrong.

  • Pull out the connected cable and plug it back into the HDMI port and immediately remember which one. I have it at number 2;
  • We connect to any free port on a laptop;
  • Or on the system unit of a personal computer;
  • Now on the remote you must turn on the button that displays all connections to the TV. It can be a button labeled “Input” or “Source”;
  • Now this section will open in the menu, where all ports and inputs are presented. Choose the one through which you connected your laptop or computer;
  • One more point. on some TVs there is also a menu that indicates the type of connected device. This is necessary in order for the image to be of acceptable quality. Therefore, find the button to change the name and select “PC” or “Notebook”;

If there is no picture on the screen, and you still see this unfortunate inscription, then move on. Also, if there is still an image, but there is no sound, then go to the last chapter.

Screen frequency changes

Windows 10

  • Right-click on the desktop. There should be displayed two squares with the inscriptions 1 and 2. 1 is your computer or laptop, and 2 is a TV;
  • Scroll down and find “Advanced Display Settings”;
  • Now you need to go to the properties of the second display, go to the “Monitor” tab and set a different frequency. If your TV operates at 60 Hz, then set this. Sometimes you need to set it to 25 Hz to work on older TVs. Click “Apply” and “OK”;

Windows 7

  • Right click on the desktop and select “Screen Resolution”;
  • In the line “Screen” you need to select the second image. so that it is in front;
  • Go to the “Additional parameters” tab. “Monitor” set the desired frequency and click “Apply”;

Updating drivers

  • Click on the “Win” and “R” buttons. We register: “devmgmt.msc”;
  • We go to the “adapters” section. There we find our card, right-click and select “Update drivers”;
  • At this point, you should be connected to the internet. Next, select “Automatic search for updated drivers”. We are waiting for the driver to download and install. If the system said that the drivers do not need updating, then you cannot write off rejoicing, as this means that they SIMply do not exist on Microsoft servers;
  • Therefore, we do it differently. go to the “Properties” of the card;
  • Next, go to the third tab and select “Equipment ID” in the properties;
  • Copy the first value and go to the site. driverslab.ru;
  • Insert the value into the search bar and click “Find”. Usually the driver will be the very first. so download it. Next, open the archive and run the “exe” file

No picture

To see which output mode is worth: you need to press the key combination “Win” and the English key “P”. After that you should see a window like sweat. Choose one of the last three options. But best of all are “Duplication” and “Projector Only”.

Try to disconnect everything you can from the TV. Including all sorts of TV-receivers, USB drives. This also applies to connections via AV ports. In general, turn it off. that’s it!

On LG TVs, there is a feature that allows you to manage connections. But she also interferes. Press on the remote control on the button with the house icon, then select “Settings”. “Additional. settings “-” General “- scroll down to the function” SIMPLINK (HDMI-CEC) “

Now set to “Off”.

No sound

  • In the lower right corner of the screen in the tray we find the speaker icon and right-click on it;
  • Select “Playback device”;
  • Now you need to select your TV, which should also be displayed on the screen and press the right button, and then select “Use as default”.

If the sound does not appear, then you also need to update the driver for the card, since often the sound comes from it. How to do it. I wrote above.

Windows 7

In Windows 7, in addition to the main connection method through the control panel, there is also a special program, which is usually in the system.

  • Type in the search bar “Connect to the projector”, or go to the program yourself through the “Start” menu.
  • After the program opens, select “Duplicate”.
  • Be sure to save any changes you made and close the program. If this solves your problem, a setup icon will appear at the bottom of the desktop of the computer monitor indicating that the correct monitor is connected.

Cleaning from malware

It happens that the signal from the laptop to the TV disappears due to the fact that viruses or other malicious programs have appeared in the equipment. Fortunately, such a problem does not occur often, nevertheless, such a breakdown cannot be completely ruled out. In order to increase the degree of protection of a computer or laptop, it is imperative to download any antivirus, and it is not necessary to purchase a license. at first, as a rule, about a month, users are provided with a free test version.

The sequence of actions is as follows:

  • activate any antivirus you like, then start the scan option by clicking on the corresponding item in the window that opens;
  • specify the “Full scan” method, then click on the “Start scan” option.

Causes

When the computer / laptop does not see TV, the monitor screen says “No signal”. This happens when HDMI is not working. The most common reasons include:

  • incorrect connection of equipment;
  • mechanical damage to the HDMI cable itself;
  • malfunction of the interface on a personal computer, TV or laptop;
  • card breakage or interruptions with card drivers;
  • incorrectly set monitor settings;
  • settings on TV are incorrectly set;
  • breakdown of the GPU processor on a laptop or computer

We will figure out how to establish the cause of the malfunction in the following sections of our article.

Windows 10

In order to configure the output of a row from a computer to a TV in Windows 10, you must follow these steps:

  • go to “Start” and click on the settings icon. usually it is in the form of gears;
  • enter the “Systems” option, then go to the “DisPlay” tab;
  • the opening window displays the displays of external monitors available for connection;
  • all changes must be saved.

Inspection of the cable for defects

When determining the reasons why the TV does not see the image, it is very important to exclude the possibility of damage to the cable itself, since the damaged wire does not transmit a signal. To check, the wire should be connected to some other device and see if the image is displayed. Thus, it is possible either to immediately identify the source of the problem, or to significantly narrow the area of ​​fault diagnosis. If the wire does not work with other equipment, the conclusion is obvious: you should replace it with a new, functional one.

Find the external input method button on the TV remote control. There are usually three options: HDMI, Source and input. Go to the proposed menus, select the input where you connected the power cable, and confirm your action.

Checking for technical problems

In some models of television equipment, the function of automatic detection of the signal source is not built-in, especially in cases where the TV was initially set to synchronize with other devices. To remedy the situation, you need to take the remote control, and then open the list of all possible signal sources: manually select the HDMI option from the list provided.

If this does not help, go to the TV settings in order to select the required connector. As a rule, modern TVs are equipped with a pair of HDMI outputs, you can see the connector’s numeric code directly below it. On the panel in the settings, specify exactly the one where the cable is inserted. Switching between these ports is possible using special buttons or by means of numbers 8 and 2.

One of the most common reasons why TV stops seeing a laptop or personal computer is a broken card. In this case, the screen displays the phrase “No signal”. In order to cope with this problem, you should update the drivers. They can be located on the installation disk or, if it is not at hand, they can be downloaded from the official website of the GPU processor manufacturer.

First, you need to study the specified technical features of the card. The fact is that not all graphics modules built into a computer support the ability to display images on two or more monitors at once. This information is usually indicated in the documentation that comes with the card kit. In the absence of this manual, specialized software can be used.

Almost all connectors can be susceptible to mechanical damage, as well as short circuits, as a result of which contacts burn out. That is why inaccurate use of technology, as well as any sudden power surge can disable the equipment, and then the computer will not see TV.

With use, the contact pad of the cable outlet on the computer often oxidizes. this can also be the reason why the device cannot detect the connection. In such a situation, it is best to contact a service center. Experienced craftsmen will rewire all damaged contacts and thereby restore the full functionality of the equipment.

Windows 8

To customize Windows 8, follow these steps:

  • go to the “Start” menu;
  • select the “Control Panel” function;
  • go to the tab “Design and personalization”;
  • find the item “Screen” and select the option “Resolution”;
  • in the window that opens, change the PC display to the option “Multiple monitors” or “Duplicate these screens”;
  • save all changes made.

Diagnostics

In order to establish the reason why the TV does not work through the HDMI cable, it is necessary to diagnose it. It includes several SIMple steps:

  • assessment of the correctness of the scheme for connecting the TV to a PC, as well as an external examination of the wires for damage;
  • checking the accuracy of the TV and personal computer settings;
  • diagnostics of the installed computer operating system for viruses and malicious software;
  • checking the relevance of the built-in card drivers.

These errors result in the TV equipment being unable to see the connected HDMI device. In this case, SIMple steps will help to solve the problem by diagnostics.

Computer settings

If there are no interruptions in the signal reception, then you should diagnose the settings of the PC or laptop. Quite often, they do not notice the TV due to incorrect parameters set in the system. You do not need specialized knowledge to repair, you just need to adhere to the most elementary instructions. Move the mouse over a free area on the screen, then right-click. In the window that appears, select the “Screen Resolution” tab, in some computer models it is called “Graphics Specifications”.

Find the best way to visually display the picture on the TV screen. Try to set the resolution as indicated in the model’s instruction manual. It’s easier to turn on the settings panel on a laptop: you just need to hold down the FnF4 buttons and hold them until the resolution that suits you is determined by itself. If this does not help, then you will have to refer to the operating system settings on the computer.

Equipment out of order

The most common reason that a TV does not show certain or all channels is hardware failure. Breakdowns in this category can be roughly divided into three groups:

  • mechanical damage to the connecting cable;
  • breakdown of a satellite dish or TV antenna;
  • receiver malfunction.

Now let’s look at all the problems in more detail. Let’s start with the cable problems. If the TV says “No signal” or it is very weak, which is why the channels are actually poorly shown, then the connecting cable is most likely damaged.

Diagnostics involves a thorough check of all plugs, as well as wires for breaks and other mechanical damage. Remember that the signal quality is directly affected by the cable. Therefore, it is very important to know how to choose the right cable.

Another justification for why there is no signal on the TV is a breakdown of a dish or a conventional TV antenna. If you are using a cymbal, first make sure that it points in the right direction. We will talk about this in more detail a little later. It is possible that the TV antenna is covered with a thick layer of dust and dirt. In the cold season, it can be covered with ice. Naturally, all this negatively affects the signal quality. Clean the surface of the device gently.

Damage to the antenna itself cannot be ruled out, for example, after a gusty wind, a certain element of the device broke. In this case, the TV antenna or satellite must be replaced.

Sometimes the prefix writes “No signal” due to a receiver malfunction. This is a very common breakdown. The main task of the converter is regulation. The decoder lowers the frequency of the satellite signal. As a result, the loss of signal quality is automatically reduced to zero. The only way to solve the problem that appears is to change the faulty receiver.

The possibility of a malfunction of the TV itself cannot be ruled out. Even devices from brands such as Philips, LV, Sony, Samsung are not immune to breakdowns. The breakage may be minor. For example, the contacts of the connector for connecting the antenna cable have oxidized. Such a malfunction is eliminated by re-soldering the damaged areas.

Carrying out technical work at the provider

Each operator periodically conducts preventive maintenance, and emergency repairs may be necessary. There is no signal during this period. There are several ways to check if the provider is working normally. If you want to know why there is no digital TV signal today, you can:

  • call the operator by phone support;
  • find information on the Internet on the official website of the provider;
  • check notifications in the receiver.

If you cannot turn on the channels to check the alerts, use the remote control to enter the receiver’s system menu. In the system menu, when carrying out repair, preventive work, the provider receives a notification “no signal”.

Cable subscribers have to deal with problems with set-top boxes. These devices often freeze. The problem is not difficult to fix. Unplug the plug from the socket, turn off the set-top box, turn it on, give time to reboot. If this technique did not solve the problem, call the managers on the hotline. Perhaps you need the help of a specialist to solve it.

Not all channels are showing

Weak signal is the reason that the TV shows only some of the channels in poor quality. Why is this happening? First, as mentioned earlier, you might have ignored the system update output. Some packages are designed to restore signal quality in certain regions. Secondly, we cannot exclude the fact that you have set incorrect settings, as a result of which the signal constantly disappears.

It is very easy to solve the problem that has arisen. However, to a greater extent, this failure is characteristic of satellite TV. Open the settings menu and then select the desired satellite and frequency. Detailed information about specific channels can be obtained by hovering over the TV channel, and then clicking on the “OK” or “Info”.

Now you need to find a suitable port. Mostly a 4-port DiSEqC is required. Select the desired port. Colored bars will appear on the screen. signal quality, save the set parameters. By analogy, we set up other satellites. Also, sometimes it is the tuner that constantly loses the signal. In this case, you need to reflash the decoder.

Now you know for sure what causes problems with the signal, as well as what is required to eliminate them.

The lack of a signal on the TV creates significant discomfort. The cause of such a problem can be technical problems, malfunctions of the operator, climatic factors. The help of specialists is not always required to eliminate it. After reading the article, you will be able to determine why there is no signal on the TV, what to do in a particular case. This will help you cope with most problems yourself.

Now you know for sure what causes problems with the signal, as well as what is required to eliminate them.

What if there is no signal on the TV? First, you need to diagnose the cause of the failure. You can do this yourself. Much will depend on the signal source: cable, digital or satellite TV. Secondly, you need to fix the problem on your own or turn to the provider for help.

Now let’s analyze the most common reasons for the lack of a signal. Sometimes the receiver does not receive a signal due to hardware breakdowns, and in some situations, system errors have become the catalyst for the failure. Sometimes external factors, especially weather conditions, affect the signal quality. However, everything in order.

Diagnostics of technical devices

The absence of a signal is most often the result of technical problems. The list of possible malfunctions is extensive. Damage can occur to the receiver, cable, antenna or dish, TV.

READ  No Signal On TV Digital TV Cause

    First of all, check the integrity of the connecting cable.
    If damaged, the signal may be weak or not. Make sure that the insulation shell is intact, there are no breaks. The damaged wire will have to be replaced. You can make repairs for minor defects, solder the broken wires, if you have experience and skills. Check antenna cable

Before purchasing a cable, consult a specialist. The quality of the transmission directly depends on the correct choice. If replacing the cable does not completely solve the problem, check the condition of the connectors. They can be damaged during operation.
Accumulation of dirt, dust, antenna icing. cymbals can cause deterioration, lack of TV signal.
Inspect the structure, if necessary, carefully clean its elements. Ensure the integrity of the receiving equipment. Strong storm winds can damage dish elements, TV antennas. If there are breakdowns, the device will have to be repaired or replaced.

Bad weather can be the reason
The problem may be caused by a defective receiver.
This device adjusts the incoming digital signal. Converter repair can only be done by a qualified technician. In most cases, the defective device must be replaced.

Signal may be missing due to faulty receiver

No equipment is insured against breakdown. If the TV does not show, there is no signal from the antenna, it is possible that the contacts in the cable connection socket are oxidized. The damaged areas must be re-soldered. It is better to entrust this work to the master.

Repair work at the operator

This reason is more related to those cases when the user is a subscriber of a satellite or cable TV provider. Where to call to find out why there is no signal on the TV today? Of course, you need to contact the Support provider, but first make sure that exactly those. work caused no signal.

You can find out about the time and duration of maintenance work on the official website of the provider. Also, such a temporary problem is defined as follows:

  • Take your receiver remote.
  • Open the settings menu.
  • Check if there is a notification about no signal in the decoder menu.

If the channels do not turn on, and a notification about no signal appears in the receiver’s system menu. This means that the reason that TV does not work is the preventive work carried out by the provider.

If you are a cable TV subscriber, then problems with signal quality may arise due to the fact that the set-top box itself is frozen. Reboot your device. Unplug the device from the mains for about half a minute, and then plug it back in. The crash may be gone.

To completely exclude the prophylaxis carried out by the TV operator, call the hotline. The managers will explain to you whether you correctly diagnosed the malfunction.

External causes

Partially this topic has already been touched upon earlier. What if I have problems with the signal after strong wind, rain or snow? First of all, you need to establish the initial direction of the antenna or satellite dish. It cannot be ruled out that a bad picture is a consequence of the obstacles that have appeared: buildings, branches, trees. If possible, fix the problem, for example, cut the branch of a tree that is interfering with signal reception.

What to do in situations when there is no signal on TV due to the fact that there are obstacles that you have no right to remove? For example, neighbors built a new building or expanded the house. The easiest way to solve the problem is to change the location of the TV antenna or satellite dish.

If the antenna / dish was initially installed correctly, but after the wind its direction changed, then this can also be considered the reason that when you turn on the TV you see the inscription “No signal”.

First of all, you need to adjust the turning angle of the dish or antenna. Pay attention to the direction of your neighbors’ antennas, do everything the same as theirs. To carry out the most fine tuning, use the angle calculator. You can find it on the official website of the provider. First, enter the location details. To get the most accurate information, use the information obtained from the GPS of your smartphone. The program will automatically calculate in which direction you need to point the antenna to improve signal reception.

Sometimes the quality of the image can deteriorate noticeably during heavy rain or wind. This is a completely natural phenomenon. Bad weather negatively affects the signal quality. Unfortunately, you will hardly be able to achieve perfect picture quality. You can try to move the antenna or dish to a more secure location if it matches the values ​​obtained using the angle calculator.
