And at least now even fashionably say: “I do not watch TV”, in many cases it is nothing more than a sinusiness. Even if it is used mainly as a monitor, a means for watching movies and video on the Internet – this is all the same TV. Unpleasant when he fails. It paralyzes plans for familiar leisure. One of the common breakdowns – problems with sound on TV. Consider more of the causes and ways to solve them.
Possible causes of lack of sound
On the interruptions in sound opening, it is necessary to react quickly, otherwise “flying” can acoustic system. To identify the cause of the breakdown of the sound transmission is not so difficult, even one who understands the device in the TV device will cope with it. The following situations are more often associated with sound problems:
- After turning on the sound technique there is no immediately;
- When switching channels, the sound row is observed – a long or short-term;
- The volume cannot be adjusted on the remote or on the device itself;
- The sound became quieter on the usual volume indicators.
The reasons why this happens is also typical. The abyss of the sound may be due to:
- The banal random turn on the “No Sound” button on the remote, a huge number of people do not notice this and do not assume that such a button is there, they cause masters on a trifling situation;
- Disturbance of the console – the batteries ended, the contacts burned out, the remote was simply failed due to the expiration of the service life;
- breakdown of the speaker system itself, which is more serious;
- Amplifier defect due to damage to wires (for example, burned contacts);
- deformation of the processor;
- broken columns or acoustic headset;
- Dropped control board.
If the device is turned on, and the sound from the speakers does not go, you can act like the risk of doing something even worse is low. You can, for example, just calmly restart the device, and it will earn in normal mode. If it did not work, it makes sense to disassemble the console. Check whether batteries work, you need almost first.
If it’s not about this, you can look at the chips and connectors at the TV.
Immediately sin to acoustics do not need, because other elements are able to break. If the sound disappeared sharply, right during viewing, probably a closure happened in the microcircuit. Continuations may be burned due to a weak connection or, which happens more often, due to voltage jumps. But when the microcircuit is out of order or blown contacts, it usually occurs the characteristic smell of Gary. Sometimes even go smoke. If this happened, the cord needs to be pulled out from the network and invite home masters. Repair needed professional.
If during the viewing instead of conventional sound, clicks, if the TV scrolls and “stutters”, if the sound row like “floats”, this situation is also required to resolve faster. If the sound sharply became weak, something in the background rattles or beeps, first check, or it’s exactly on TV. A laptop or other technique can be connected to the device, check their settings. If the TV is buzzing, while watching channels, this step is skipped.
The following reasons for the periodic deterioration of the sound or constantly established poor sound on TV are possible
- problems with radio channel – in this case, you need to invite a specialist for repair;
- Processor malfunctions – also have to contact the service center;
- Failure in the memory card – and this problem without professional help is not solved.
Hope that everything will be held by itself,. Of course, if you turn on / off the TV, and the problem has disappeared, it is not necessary to search again.
But if the distorted sound is that and the case reminds of yourself, it is time to call the masters.
Appearance with late
The sound can fall behind the video or not to coincide with it, to appear with a serious slowdown – this is also a fairly common type of breakage. Experts say the following:
- If when the device is turned on, there is no sound, but it appears after a while, from 10 seconds to several minutes, it can be in the breakage of the connector on the TV; You can correct this problem in the service center;
- If the sound is lagging behind, the dynamics breakdowns are not excluded, but only the master can be diagnosed;
- Finally, it can be in shedding contacts, and this is also eliminated in the service center.
Hazardous story – try to eliminate the breakdown itself, if there is no confidence in his own experience on this part. Sound stopped working, all safe methods of self-diagnostics and repair did not help, it is necessary to solve a question through the service center.
Disappearing while viewing
If the sound has disappeared sharply during viewing, and in the room there was placed at the place, the signal amplifier could burn, could burn and responsible for the sound of the microcircuit. TV immediately need to turn off, remove the cord from the outlet.
If the sound disappears while viewing from time to time, but then he is restored by itself, it is probably the case in overheating of some electronic components. It overheats, cools, and then turns on again. But there is nothing to rejoice: sooner or later this component burns, and the full repair is still to be.
If the sound and video on the TV simultaneously disappear, make sure that the device is not connected to the TV. That is, switch to normal channel. If on the channel everything is fine, the case is most likely in the cable. Such cables can completely fail: then the picture disappears and the sound. But often they break partly, then the sound disappears with a bright running screen. In the playback of sound in the broadcasting, there will be no problem.
Important! Sound disappears on one or more channels. If only in one, most likely, the reason is not in the TV, but in the violation of the broadcast of a particular channel.
No sound when you turn on
Before carrying a 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 banal causes alleged breakdowns. Again, do not forget about the “Turning off of the sound” button on the remote. She can be unclaimed all the time of use with a remote control, but one day someone will randomly press her (for example, a child), and all then only guess how it was so simply broken TV.
If it is not exactly in the remote, but it can fail, you need to turn off the TV. Get the cord from the outlet, wait a couple of minutes. Turn on the device again by running it off the remote. If the sound did not appear, it’s more likely, in “Sorting” speakers or breakdown of contacts.
Check the possible cause of breakage can be connected to the TV headphone. If the sound goes into the headphones, then they broke the speakers in the TV. Headphones can be turned off because you need to take the phone and call the master. Or just ship the equipment into the car and drive it to the service center.
If the TV has become noticeable to work quieter with the same indicators on the remote control, perhaps on the remote, someone imperceptibly turned on the night function. Or turned on and forgot about it. Perhaps the console itself does not work, but this is a rare case in this situation.
If the problem does not disappear itself, and the switching on / off does not help, you will also have to turn to the master. It distributes the speaker system, check the speakers, chips, amplifiers.
If automatically sound does not switch, that is, it is not added and not reduced, again, you need to start with the checks. If the sound without a remote control is regulated, it’s time to change the remote. If on the TV manually, the adjustment is also impossible, you may need to reset the settings to the factory. It is possible to update the TV, which happens constantly, in a particular case did not pass, from here and sound problems. For example, the update began, and the owner of the TV directly in the process turned it off, the main requirement of installing a new firmware is not fulfilled. From here and sound problems.
Other “therapy” as a rollback for the previous version of the firmware. If the TV after the update itself does not start, you need to manually arrange a restart. And the owner should see the notice on the screen that the update has been successfully established.
There is such an opinion that to organize a comfortable television sound, the device itself can be connected to an external speaker system. Today 4 species of such systems are actively used: simple acoustic stereo systems, multichannel compact systems of surround sound, full-scale systems of the “home theater” type, saunbars. Simple acoustic systems will be convenient in the following cases:
- I do not want to overpay for unnecessary volumetric sound;
- The musical background is not as important as dialogues in the film;
- The room in which the TV is worth it is not so great to provide it with really cool chic sound;
- be big room, but I do not want to clutch it with columns.
Compact multichannel sound system will suit those who want to improve the sound characteristics of the TV without major investments. 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 willopach will be very high quality.
Connoisseurs of watching movies with an ideal sound track will be satisfied with this acquisition.
And another couple of important expert councils on the proper operation of the TV.
- Perfectly if the TV is away from the windows. And also do not put it next to the heating device. Between windows – another unsuitable TV area. All this will lead to the faster breakdowns, including and associated with sound.
- Due to the electrostatic field around the TV, many dust accumulates. And it will be frequent cause of breakdowns if it is not removed on time. At least a couple of times a year you need to remove dust with a vacuum cleaner. Naturally, the TV should be disconnected from the power supply.
- If it comes to the LCD TV, you should not give it to work 6 and more hours in a row. You need to protect the technique from shocks, to change the light bulb on time. When transferring the device to another room, it should be done as much as possible.
- Plasma TV is cooled by itself, a special fan is built into it. And if some changes occurred in the fan (sound), it makes sense to call the masters for diagnosis.
- LCD monitors and plasma TVs are wipe with special napkins that are sold in electrical stores.
- You can not arrange a TV such stress as frequent switching on / off.
If you follow these ordinary tips, the risks that the sound or picture is dropped in the TV. Technique will serve for a long time and will delight impeccable work every day.
