TV Sound Problems: 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 videos 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 most common breakdowns is problems with the sound on the TV. Let's take a closer look at the reasons and ways to solve them.

It is necessary to react promptly to interruptions in sound supply, 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 wire damage (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. Checking whether the batteries are working should be almost the first thing.

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. Professional repair is needed.

If, during viewing, clicks appear instead of normal 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 rattles or squeaks in the background, 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 hums 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 also have to contact the service center;
• failure in the memory card - and this problem cannot be solved without professional help.

It is not worth hoping that everything will pass by itself. Of course, if you turn on / off the TV and the problem disappears, you don't need to look for it again.

The sound may lag behind the video 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 the device is turned on, but it appears after some time, from 10 seconds to several minutes, the matter may be in the breakdown of the connector in the TV; you can fix this problem at the service center;
• if the sound lags, breakdowns of the speaker 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.

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, the cord must be removed from the socket.

If the sound disappears during viewing from time to time, but then it recovers by itself, it is likely that the problem is 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 ahead.

If the audio and video on the TV disappear at the same time, make sure that the matter 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. In this case, there will be no problems with the playback of sound in TV broadcast.

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 clicks on it (for example, a child), and then everyone just wonders how the TV broke down at once.

If the point is definitely not in the remote control, and in fact it can 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 it is the speakers in the TV that 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.

If the TV began to work perceptibly quieter with the same indicators on the remote control, it is possible that someone on the remote control 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.

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, in this particular case did not go through, 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 the 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.

There is an opinion that in order to organize a comfortable television sound, the device itself should be connected to an external speaker system. Today, 4 types of such systems are actively used: simple acoustic stereos, multichannel compact surround sound systems, full-scale home theater systems, and soundbars. Simple speaker systems will be useful in the following cases:

• don't want to overpay for unnecessary surround sound;
• the background music is not as important as the dialogues in the film;
• the room in which the TV is located is not big enough to provide it with really cool chic sound;
• the room is large, but you don't want to clutter it up with speakers.

This compact multi-channel sound system is perfect for those who want to improve the sound performance of their TV without a major investment. But full-scale systems are suitable for those who intend to arrange a real home theater in a large room. In this case, the sound delivery will be of very high quality.

And a couple more important expert tips on how to properly operate your TV.

• It's great if the TV is located away from windows. And also do not put it next to a heating device. Between the windows is another unsuitable area for a TV. All this will lead to the fastest breakdowns, including those related to sound.
• Due to the electrostatic field, a lot of dust accumulates around the TV. And it will be a common cause of breakdowns if not removed in time. Vacuum the dust at least a couple of times a year. Naturally, the TV must be disconnected from the power supply.
• If we are talking about an LCD TV, you should not let it work 6 or more hours in a row. It is necessary to protect the equipment from blows, change the backlight bulb in time. When moving the device to another room, you should do it as carefully as possible.
• Plasma TV cools itself, it has a built-in special fan. And if there are any changes in the fan operation (sound), it makes sense to call the wizard for diagnostics.
• LCD monitors and plasma TVs should be cleaned with special wipes, which are sold in electrical stores.
• You can't stress the TV like frequent switching on / off.

If you follow these simple tips, the risks that the sound or picture will "fly" on the TV are dramatically reduced. The equipment will last a long time and will delight you with impeccable work every day.
