Check system settings
Open Start. Control Panel. Sound and check all parameters. Here in the Control Panel, you can open the menu of your IDT or Realtek audio codec, and see if their settings are normal.
Frequently encountered queries in search engines, according to statistics, are issues related to the lack of sound, as can be seen in the screenshot from Google below.
Check your speakers
If external speakers are used to reproduce sound, check that they are plugged in, that all wires and plugs are connected, and that the volume control is not turned off.
Why is there no sound on the laptop?
This problem can occur on any laptop with any operating system, therefore, below we give a list of actions that must be performed sequentially for all. Perhaps after one of them, the sound that is missing in the laptop will appear. The problem can be caused by two factors: software or hardware. Let’s start SIMple and move on to more complex.
Is sound muted in Windows?
Pay attention to the icon in the system tray (lower right corner of the screen). If there is a red crossed out circle next to the image of the white speaker, you need to increase the volume by moving the slider up.
Reboot your laptop.
If the sound is missing for the first time, restart your laptop. It will probably appear already when Windows starts loading.

ASUS X200CA: 11-inch touchscreen. Resurgence of netbooks?
Open Start. Control Panel. Device Manager. In the list of devices, find the Sound and game controllers tab. Right-click on your codec (IDT or Realtek HD) and in the context menu that opens, try to disable-enable the device, or update the drivers. You can also open the laptop manufacturer’s website in the browser, find your model on it and download sound drivers for it.
The above steps will fix the problem 99% of the time. The chances of a malfunction of the speakers themselves are very small, so if you are not successful, contact a more experienced friend or a service center. You should not write in the comments requests to help return the sound on the laptop, it is useless, since it is impossible to do this remotely without seeing your laptop and the settings set in it before your eyes. The problem often lies in the little things, like an extra checkbox, the adjustment slider dragged in the wrong direction, the driver is not installed.
Causes of breakdowns
TV models of different brands have the same device and the same reasons for the failure of the audio signal transmission. The most common of them are malfunctions of the following components:
Speakers. On old TV sets, parts eventually develop their resource, and on a new model, speakers with a factory defect can be installed;
Sound amplifier. The device is sensitive to voltage drops in the network and quickly burns out with an unstable current;
Chip. The most vulnerable point of any electronic equipment. Elements of the television system may fail due to burnout or moisture ingress;
Contacts and connectors. Frequent connection of additional equipment, headphones and gadgets to the TV leads to natural mechanical wear and tear of these units or their deformation;
The computer is not properly connected with the HDMI cable. In this case, you need to study the instructions in detail and make the appropriate settings.
The situation when the sound on the TV does not work can be faced not only by the owners of old devices. Newer TV receiver models are also prone to this type of breakdown. In case of malfunctions with sound, it is impossible to fully watch television broadcasts, enjoy films and sports matches, and show multimedia files from a computer. Consider why defects occur and what can be done in this case.
What to do if TV sound doesn’t work?
If when you turn on the TV set there is an image, but there is no sound, you need to try to identify the cause of the problem and, if necessary, call the wizard. First of all, it is recommended to turn off and turn on the device again. As with other electronics, it is often enough to reboot the TV to restore it to work. Next, you need to make sure that working batteries are installed in the remote control, check the sound level settings on the remote control and on the device panel.
If the imaginary “malfunctions»Are excluded, but there is no sound on the TV, the reasons lie in mechanical breakdowns of parts and assemblies. You can identify common types of breakdowns yourself, without using complex diagnostic equipment:
The serviceability of the speakers is checked by connecting headphones or external speakers. If the sound appears, then the built-in speakers are out of order, they will need to be replaced;
If there is a quiet sound, but it is impossible to increase the volume, then the radio channel or the control processor is broken, the memory card may fail;
When connecting a computer to the TV with an HDMI cable, you need to check the speaker settings on the monitor in the lower right corner. In some cases, for the correct interaction of the equipment, you need to install drivers. To do this, go to the manufacturer’s website, download the necessary updates and follow the instructions of the system;
During operation, the TV sound disappears from time to time, and then reappears. Most often, the cause of the defect is wear of the speaker contacts or damage to the connector;
If the sound suddenly disappeared during viewing, while there is an obvious burning smell, this is a sure sign of a burnt chip. It is necessary to immediately disconnect the equipment from the mains. such a breakdown can lead to a fire and explosion of the device.
A television is a complex technical device. There are many other reasons why sound may drop out or sound degraded. An accurate diagnosis can be made by a master. To do this, the circuit is sequentially called with a multimeter until a faulty part is detected, or a special stand is used. Repair in most cases consists in soldering contacts or replacing a failed component.
A modern TV is an expensive household appliance. If the sound disappears on the device, you can eliminate superficial problems yourself and correct the settings:
Mute mode is on;
Elimination of malfunctions associated with mechanical damage should be trusted only by a specialist. Unskilled intervention in a complex electronics device leads to an aggravation of the problem and breakdown of other parts or complete failure of equipment.
There is no picture on the TV, but there is sound. how to fix the problem
In our time, a rare person does without a TV. Every year the models become thinner, larger and offer more and more new functionalities. Modern plasma screens with Smart TV technology have little in common with devices that were on sale some ten years ago. However, the commonality between the old and new generations still remains. breakdowns and malfunctions still happen. The reasons for this can be very different: blows, falls, ingress of moisture and direct sunlight, or an elementary marriage. In this article, we will take a closer look at what to do if the TV has lost the image, but there is sound. Let’s figure it out. Go!
What to do if there is no picture on the TV
First, it should be noted that a SIMilar malfunction occurs quite often in a variety of brands of TVs. TVs of all brands are equally affected by this: Samsung, LG, Philips, Sony, Panasonic and many others. Therefore, it makes no sense to blame the manufacturer.
There are many reasons for the absence of an image on the screen, and it is unlikely that you will be able to determine it yourself by eye. Most likely, you will still have to contact a service center or other repair service. It all depends on the nature of the problem. on this below.
It happens that when you turn on the TV, a splash screen with the manufacturer’s logo appears first (LG, Samsung, Philips, and so on), after which the screen SIMply goes out. With this, you can change channels and hear the sound. Some users noticed that after a while the image appears, but when you turn it on again, everything repeats and there is no picture. In this case, try the following tips:
- Check the cable connection of the receiver as it may have come off. Make sure the cord is plugged in securely. If there is no signal from the set-top box, many TVs SIMply turn off the screen.
- Also, the problem may be in the cable itself. The wire may be damaged or SIMply be of poor quality. This applies not only to HDMI cables, but also to cables with bells. In them, the transmission of the audio signal and the signal occurs through separate wires, and the problem may lie SIMply in a broken wire or poor contact. In some cases, replacing the wire can correct the situation.
- Check the power cable. It must also be securely connected.
- Some users have found a rather original way to solve the problem. to increase the volume to the maximum (or close to it). After a few seconds, the image will appear and then you can set an acceptable volume level.
Please note that all the above tips will only help if the screen is working. This is indicated by the splash screen when the TV is switched on. If the screen saver is absent and the screen is constantly dark, this already indicates that some component of the TV that is responsible for the image is out of order.
There are several components, failure of which can cause no picture on the screen. It is quite common that the inverter breaks down, which supplies voltage to the backlight lamps. The lamps themselves can also fail, and this, in turn, provokes a breakdown of the power supply. In addition to the faults listed above, it is not uncommon for a matrix or motherboard to break down. Also, the problem may lie in the loops, converter and decoder. In this case, non-working parts and elements will have to be replaced with new ones.
It is not recommended to carry out repairs on your own, since modern TVs are rather complex devices, and you run the risk of aggravating the situation even more. If the above SIMple tips did not help, then the best solution would be to turn to professionals, since the TV will need to be disassembled. It can be a service center of a manufacturing company or a private office, where repairs will be carried out efficiently and quickly.
One way or another, it is impossible to determine what is the reason for the breakdown of your TV without a thorough inspection. In any case, the device must be disassembled and diagnosed for non-working parts and components. It is best if this is done in a workshop with appropriate conditions, however, if you do not like this option, then many telemasters provide all these services at home.
Of course, replacing some parts can cost a pretty penny, but it should be noted that matrices or motherboards themselves rarely fail. Usually, damage occurs as a result of physical damage to the part, for example, when the TV falls or gets wet. In general, you cannot do without a telemaster.
Now you know what to do if the TV has lost the picture, but there is sound. You will also understand what could be the reason for such a malfunction. Write in the comments if this article was useful for you, share with other users your experience in solving SIMilar situations.
In fact, if your TV has no sound, this does not mean an unequivocal breakdown of equipment. It doesn’t matter what kind of TV you have. Samsung or Philips, LG or Sharp. CRT, plasma or LCD. The principle of their operation is in many ways SIMilar and, before calling the master, just check the device visually.
No sound on TV when PC is connected via HDMI
The subtle point is connecting a computer to a TV. Let’s say you’ve downloaded an interesting movie from the Internet and now you want to watch it on a large LCD screen using an HDMI cable. One problem. when connecting hdmi from a PC, there is no sound on the TV. This may be a signal that the contacts have moved away from the connector, and it is SIMply impossible to output sound to the TV. Loose contact is the third most popular reason for “silent” television. Even if you connect correctly, there will still be no sound until the pins snap into place. In this case, there is an image, but the sound from the computer is not output to the TV speakers.
In practice, the “breakdown” may not be so bad at all. Some of the reasons for missing TV sound may be ludicrous, but they are very common. Often people SIMply forget to increase the sound on the remote control, and it seems to them that it has disappeared. Therefore, first of all, see if everything is in order with the settings. Forgot to switch them, that’s why there is no sound. Also, don’t forget to check the batteries in the remote control.
However, these kinds of failures. those that you can easily fix on your own. are just the tip of the iceberg. If you have lost sound, then most often the cause of the breakdown lies in the bowels of the equipment. It is better not to go there on your own. The scheme of the device of all TVs is approximately the same, and therefore a qualified specialist will undertake the repair of any brand: Toshiba, Sony, Daewoo. for the master it does not matter. If the sound does not work, then it is likely that something is broken in the filling.
Why did the TV sound disappear??
No sound on the TV makes it impossible to watch your favorite shows. It is wrong to think that this problem only applies to old devices: unfortunately, the sound can suddenly disappear even on a TV purchased yesterday. Often the reason lies on the surface and you can solve it yourself at home. But it is not uncommon for a breakdown to occur inside, and you will certainly need the help of a qualified specialist. What to do if there is no sound on the TV?
We identify the reason for the loss of sound on the TV
What problems can lurk inside the TV? The most common option due to improper handling of equipment is moisture. Even if your TV is in a dry room, it is not flooded with water from the window when it rains, this will not always be a guarantee of safety. Many housewives wipe the equipment with damp rags, spray indoor plants with spray guns. and then there is a risk that moisture will still penetrate into the TV. And this can be fatal for the correct operation of the microcircuits. The microcircuit just got wet. and the sound on the TV instantly disappeared.
So, microcircuits are the first vulnerability of every TV. They influence the presence of sound. BBK, Supra, Akai and others have yet to come up with a versatile option that can withstand moisture. Of course, it is best to avoid such situations, but once the problem has happened, you will need to call the wizard. Self-repair of equipment can only aggravate the situation, and in the case of such a complex device as a TV, it can become dangerous for the user.
Speaker failure is the second most common cause of no sound on the TV. The TV itself may be fine, but if the speaker is broken, no sound will appear. Only a competent master can diagnose this problem and find solutions. You should not unscrew the speakers on your own, if you are not a specialist, in 70% of cases this only leads to more complicated breakdown and damage to more parts of the TV.
So, in addition to the typical everyday reasons caused by the user’s absent-mindedness, the following main ones can be listed:
- Ingress of moisture;
- Damage to microcircuits;
- Broken speakers;
- Bad contacts.
Breakdowns of this kind should not be attempted with your own hands. Here lies the danger of further disrupting the operation of equipment and, as a result, buying a new one. You always need to call the help of a qualified specialist. it’s good that today such a service as repairing TVs at home is also available. Whether your TV is a JVC or Rolsen brand or any other, an experienced TV technician will always diagnose the problem and easily fix the equipment. If you lose sound, don’t despair! Call by phone 8 (495) 707-05-05.
If, during viewing, clicks appear instead of the usual sound, if the TV wheezes and “stutters”, if the sound sequence seems to “float”, this situation also needs to be resolved faster. If the sound suddenly becomes weak, something in the background rattles or squeaks, check first, or it’s definitely on the TV. Maybe a laptop or other equipment is connected to the device, you need to check their settings. If the TV buzzes itself while watching channels, this step is skipped.
Possible reasons for intermittent sound degradation or persistently poor TV sound:
- problems with the radio channel. in this case, you need to invite a specialist for repair;
- problems with the central processor. you will also have to contact the service center;
- a failure in the memory card. and this problem cannot be solved without professional help.
It is not worth hoping that everything will go away by itself. Of course, if you turn on / off the TV and the problem disappears, you don’t need to look for it again.
Problems with sound on TV: causes and solutions
And although now it is even fashionable to say: “I do not watch TV,” in many cases this is nothing more than slyness. Even if it is used primarily as a monitor, the medium for watching movies and on the Internet is still the same TV. It’s unpleasant when it breaks down. This paralyzes the plans for the usual leisure. One of the common breakdowns is problems with the sound on the TV. Let’s take a closer look at the reasons and ways to solve them.
Possible reasons for no sound
It is necessary to react to interruptions in sound supply promptly, otherwise the acoustic system of the device may “fly”. It is not so difficult to identify the cause of the breakdown of the audio transmission; even those who understand little about the device of TVs can cope with this. The following situations are more likely to be associated with audio problems:
- after turning on the technique, there is no sound immediately;
- when switching channels, an abruptness of the sound row is noted. long or short;
- the volume cannot be adjusted either on the remote control or on the device itself;
- the sound became quieter at the usual volume levels.
The reasons why this happens are also typical. Sound can be lost due to the following:
- the banal accidental activation of the “silent” button on the remote control, a huge number of people do not notice this and do not assume that there is such a button, they call the wizard for a trifling situation;
- disruption of the remote control. the batteries ran out, the contacts burned out, the remote control SIMply failed due to the end of its service life;
- breakdown of the speaker system itself, which is already more serious;
- amplifier defect due to damage to the wires (for example, burned out contacts);
- deformation of the processor;
- broken speakers or acoustic headset;
- burned out control board.
If the device is turned on, and the sound does not come from the speakers, you can act on your own. the risk of doing something even worse is low. You can, for example, just calmly reboot the device, and it will work normally. If that didn’t work, it makes sense to disassemble the remote. Check if the batteries are working, you need almost first of all.
Lack of regulation
If the sound does not switch automatically, that is, it does not increase or decrease, again, you need to start by checking the remote control. If the sound can be controlled without a remote control, it’s time to change the remote. If, however, manual adjustment is also not possible on the TV, you may need to perform a factory reset. Perhaps the update of the TV, which happens all the time, did not go through in this particular case, hence the problems with the sound. For example, the update has started, and the owner of the TV turned it off right in the process, then the main requirement for installing a new firmware has not been met. Hence the problems with sound.
There is no other “therapy” like a rollback to the previous firmware version. If the TV does not start itself after the update, you need to manually restart it yourself. And the owner should see a notification on the screen that the update has been successfully installed.
No sound when turned on
Before taking the TV to the service, you need to make sure that the volume button is not at zero. Oddly enough, but people forget to check first the banal reasons for the alleged breakdown. Again, don’t forget about the mute button on the remote. It may be unclaimed all the time you use the remote control, but one day someone accidentally presses on it (for example, a child), and then everyone just wonders how it was that the TV broke down at once.
If the point is definitely not in the remote control, and in fact it may fail, you need to turn off the TV. Remove the cord from the outlet, wait a couple of minutes. Turn on the device again by starting it from the remote control. If the sound does not appear, it is more likely that the speakers are shrunken or the contacts are broken.
You can check the possible cause of the breakdown by connecting headphones to the TV. If the sound enters the headphones, then the speakers in the TV are broken. The headphones can be turned off, because you need to take the phone and call the master. Or just load the equipment into the car and take it to the service center.
There is no need to sin on acoustics right away, since other elements are also capable of breaking. If the sound disappeared abruptly, right during viewing, it is likely that there was a short circuit in the microcircuit. Contacts may burn out due to a weak connection or, which happens more often, due to voltage surges. But when a microcircuit fails or burned out contacts, a characteristic burning smell usually arises. Sometimes there is even smoke. If this happens, the cord must be pulled out of the network and the master must be invited home. Repair is needed already professional.
If the TV has become noticeably quieter with the same indicators on the remote control, it is possible that someone on the remote has quietly turned on the “Night” function. Or turned it on and forgot about it. The remote control itself may not work, but this is a rare case in this situation.
The sound may lag behind or not coincide with it, appear with a serious slowdown. this is also a fairly common type of breakdown. Experts say the following:
- if there is no sound when you turn on the device, but it appears after some time, from 10 seconds to several minutes, it may be a breakdown of the connector on the TV; you can fix this problem at the service center;
- if the sound lags, speaker breakdowns are not excluded, but only a master can diagnose this for sure;
- finally, the case may be in loose contacts, and this is also eliminated in the service center.
It is a dangerous story to try to fix a breakdown yourself if you are not confident in your own experience in this area. The sound stopped working, all safe methods of self-diagnosis and repairs did not help, it is necessary to resolve the issue through the service center.
Disappearing while watching
If the sound disappeared abruptly during viewing, and there was a smell of smoke in the room, the signal amplifier could burn out, and the microcircuit responsible for the sound could also burn out. The TV must be turned off immediately, unplugged.
If the sound disappears during viewing from time to time, but then it recovers by itself, it is probably due to overheating of some electronic components. It overheats, cools down, and then turns on again. But there is nothing to be happy about: sooner or later this component will burn out, and a full-fledged repair is still to be done.
If the sound is lost on the TV at the same time, make sure that the problem is not in the device connected to the TV. That is, switch to the normal channel. If everything is fine on the channel, the problem is most likely in the cable. Such cables can completely fail: then both the picture and the sound disappear. But often they break partially, then the sound disappears with a bright working screen. There will be no problems with playing sound in TV broadcasts.
Missing sound while watching
The reason that could cause problems with sound is damage to the microcircuit. precisely, its burnout due to voltage surges, overloads or poor-quality power supply. You can calculate the problem by the unpleasant smell of burning, which appears immediately after the loss of sound.
You must immediately disconnect the TV from the mains and make sure that there is no fire. After. seek help from the master. It is not recommended to repair the damage yourself.
The microcircuit can also suffer from moisture ingress. To wipe dust off the TV, some users use a damp cloth or spray bottle. There is a risk that moisture gets inside and spoils the microcircuit, albeit a small one. Situations are best avoided, because replacement parts for modern LCD or plasma monitors are expensive. If the microcircuit was nevertheless so damaged, it is worth calling the wizard. Self-repair can be dangerous for the user.
If there is no burning smell, but suddenly the sound on the TV (LG or other) disappeared, you can try to disconnect the TV device from the network, wait up to 10 minutes and then turn it back on. If the sound appeared. the reason could be overheating of the TV or a malfunction of the microcircuit.
No sound when turned on
It may be caused by poor contact between the speakers and the TV motherboard. In this situation, you can try to turn off and then turn on the TV, if the result is the same. you need to look for the reason further.
Check if the speakers are working properly. You can try connecting headphones, then speakers. If the problem is not with the connectors, it is possible that the speakers have SIMply expired. But in the case when the TV was bought quite recently, the reason is clearly a factory defect or mechanical damage.
Another, albeit infrequent, reason is the breakdown of the part of the cable that is responsible for audio transmission. In this case, a cable replacement is required.
What to do if the sound on the TV is missing. 5 topical reasons and tips for troubleshooting
Home TV sound can be lost not only with older models. Users of modern TV monitors purchased recently may also face this problem. The reasons can lie both on the surface and hiding inside the device. Why there is no sound on the TV and what can be done about it. in the article.
Loose contacts and connectors
There are connectors on the panel of TV monitors (mainly on the back) that are used to connect an additional headset: headphones, mobile gadgets, computers, etc. Regular reusable connection and disconnection of equipment over time leads to wear, poor contact and loosening knots.
The reason why the sound disappeared on a Samsung TV or another brand is that the contacts moved away from the connector.
What to do to fix the problem yourself:
- Remove and check the plugs that connect to the speaker.
- Make sure there is a signal at the output of the microprocessor.
- Check if voltage is supplied to amplifier.
- Tap lightly on the speaker cone. maybe the contact has come off.
- Using an indicator screwdriver (working side), touch the amplifier input to see if the signal is reaching the speakers.
Attention: This way you can find the probable causes of breakdowns, but you need to perform the actions with great care so as not to get an electric shock.
If the contact nodes are broken, the situation can be resolved using a multimeter, for example, NEO 94-001, (a special electrical measuring device), which will help find the damaged part. In the case of a broken connector, it can be removed and replaced with a new one.
Broken speakers or a connector may be a factory defect or mechanical damage. Improper monitor assembly is another factor that can cause loose contacts. It is important to check the speaker setup on the monitor when connecting via cable.
Sound too quiet
When connected to a laptop TV, the reason for the quiet sound may be related to the settings of the latter.
The inability to increase the volume, despite the fact that the control on the remote control is set to maximum, indicates a breakdown of the radio channel or control processor (needs to be changed). Memory failure may also be the cause. Diagnostics and repair of the TV will be required.
Reasons why there is no sound on the TV
Breakdown can be caused by many reasons, and improper handling of the device is far from the main one. Build quality, service life and operating conditions, model features, etc. all this can become a trigger for problems.
Accidental self-mutilation or setting the volume level to minimum are common reasons for the loss of a sound signal. If, after clarifying these points, the sound did not appear, the reason is much deeper. What can be associated with the lack of sound on the TV. more.
Important: Having no experience in repairing plasma TV monitors, as well as in case of impossibility to fix the problem yourself, it is better to contact the technical service.
Sound comes later
When you turn on the TV, there is no sound, but after a couple of seconds it appears. The result of a malfunction may be speaker breakage, loose connectors, or poor contact between the device modules. All worn parts must be replaced.
Checking all faults according to the list. checklist
In order not to have to carry the monitor to a specialist in vain, you first need to make sure of the following yourself:
- the volume level on the remote control is higher than one;
- mute mode is inactive (the button should not be pressed);
- the signal source is working properly. some TV channels can sometimes be broadcast without sound;
- the settings have the correct sound output. speakers;
- no other equipment is connected to the headphone jack;
- the remote control is working. perhaps you just need to replace the batteries;
- speakers are not disconnected.
After making sure that all the items on the list have been passed, but there is still no sound, you need to evaluate possible household breakdowns:
With the help of these tips, you can establish the reason why the sound on the TV disappears, and even eliminate some yourself. With regard to mechanical damage (malfunction or defects in parts), specialist assistance will be required. Unqualified intervention can only aggravate the problem and lead to device failure, or even harm the user.
