Why does the TV sound become quieter when the phone is on a call?

If the volume of the mobile phone handset is low, it is recommended: 1During a call, use the volume up button to turn up the sound.

2.Some machines support the "louder volume" function, please turn on this function when talking and observe whether the handset volume is normal. 3.

Check that the handset position is occluded. 4.Shut down, restart, or try to change to another quieter location.

If the problem persists after the above operation, please bring the purchase invoice, warranty card and machine to the Samsung service center for professional after-sales engineers to help test.

Just like when you drive a car connected to Bluetooth to open the navigation and put it on**,When the navigation speaks**will also be whispered accordingly,This is another primary and secondary distinction of the device,You are the main when you are talking,Then the TV sound will be correspondingly smaller。 After hanging up**, it is back to normal.

When talking on a mobile phone, the sound of the TV will not change. You feel like the TV is getting quieter, and that's just how you feel.

Maybe this TV is when the smart TV is connected externally**. His voice will be quieter. Sister Hua may be that the signal of this TV set is interfered with by the mobile phone signal. So there was no sound in his hands, on his TV.

Hello, mobile phone calls will not affect the TV, or turn it down yourself, I hope mine can help you.

There is also the issue of signal interference.

No, how can it suddenly become smaller, it's a psychological effect, and it won't be a small phone call TV sound meter.

There are several reasons why cell phone calls have become quieter:

Poor network conditions, poor call signal transmission, resulting in a decrease in call volume, and problems with the mobile phone speaker itself will also lead to low call sound.

There is no problem with your own mobile phone, but there is a problem with the other party's mobile phone, which will also cause such a situation.

Phone calls became quieter and the volume was turned down.

Then click "Volume" in the "Volume" dialog box, and then turn "Volume" to the maximum.

Main information:

Television uses electricity to transmit visual images of the event in real time. Similar to movies, TV uses the visual residual effect of the human eye to show a still image with a gradual change of frames, forming a visual living image.

The transmitter of the TV system converts the various fine parts of the scene into electrical signals according to brightness and chromaticity, and transmits them sequentially. At the receiving end, the luminance and chromaticity of each fine part are displayed according to the corresponding geometric position to reproduce the entire original image. The scanning system of television signals in various countries is not exactly the same as that of channel broadband, and is distinguished by Latin letters according to the recommendations of the International Radio Advisory Committee (CCIR).

The sequential sampling, transmission, and reproduction of TV signals from point to surface is done by scanning. The TV scanning system varies from country to country, but in China it is 25 frames per second and 625 lines per frame. Each line is scanned from left to right, and each frame is scanned in two fields from top to bottom in odd lines and even lines to reduce the feeling of flicker.

Image information is transmitted during the scanning process.

When the scanning electron beam returns from the end of the previous line to the start point of the next line, the line of reverse return should be blanked. A line-field synchronization signal is transmitted during line-field blanking to synchronize the received and received scans to accurately reproduce the original image.

There are two main reasons why the sound is too low when watching TV on the phone.

The microphone of the mobile phone itself is very small, and the maximum sound will be very small, and there are some models of mobile phones that are like this, the sound is particularly small, there is no way, the main problem is the microphone, how to put it is not big.

In this case, there is no choice but to change the phone. The microphone cannot be changed casually, and sometimes it is prone to other failures.

There is also a situation where there is a problem with your system settings.

Open the settings by yourself and turn the sound to the maximum, sometimes the system adjusts itself, and sometimes it is when you touch it, and the sound becomes very quiet.

Whatever the reason, just turn up the sound to the maximum yourself, and just pull all the sound keys to the head.

Turn up the volume of the phone, and the operation method is as follows, taking the Redmi phone as an example:

First, open your phone and "Settings";

Second, click in turn: "All Settings" - Sound and vibration "- Volume";

3. Then click "**Volume" in the "Volume" dialog box;

Fourth, then turn the "** volume" to the maximum.

Changing mobile phones does not have this problem.

1. Use the remote control of the TV to adjust the volume of the TV to the middle value, and then put away the remote control of the TV, and only use the remote control of the set-top box to control its volume.

2、The volume of the TV suddenly decreases, first confirm whether it is the volume of the set-top box or the volume of the TV,If only the volume of the set-top box is increased to the maximum,And the volume of the TV is very small,This phenomenon will occur。

3. If you confirm that the volume of the TV and set-top box is the largest, the sound is still very small, there are two big possibilities:

1)Software problem,That is, the volume non-linear meter of the TV is caused by an error,The solution is to enter the factory menu of the TV,There is an option to adjust the non-linearity of the sound,As for the method of entering the factory menu,You may need to consult customer service。

2) Hardware problems, the audio decoding circuit of the motherboard has a problem, and after-sales maintenance is required.

The first thing to do is to determine why the volume is getting low. Is it because the remote control is mixed, or maybe there is a problem with the TV. If you can't adjust it yourself, then you can only find after-sales.

If the volume of the TV suddenly decreases, it may be because the speaker of the TV is broken, so this problem occurs.

If you're also using an IPTV or a TV box, check to see if the volume on these devices is turned down.

Did you sit on the remote control?

If it suddenly becomes smaller, then it should basically be a problem with the TV station. If there is no problem with normal TV, then it is a problem with the TV station. You can directly use the remote control to control the volume of the TV, just increase the volume.

Summary. What's the reason for the TV to suddenly get louder or quieter? 1. Check whether the volume adjustment is abnormal caused by short circuit or leakage of the TV remote control or button panel, so the volume is up and down, and the volume is uncertain; Generally, it can be solved by replacing the remote control use;

2. Check whether there is a problem with the input of the signal source, such as whether the connection between the TV and cable TV, digital TV set-top box, *** machine and other equipment is in good contact, if the loose contact is poor, the problem may occur, reconnect and fix it;

3. Check whether there is a problem with the program source of the current program channel, if there is a problem of volume fluctuation in the program source itself, it can generally be solved by switching the program channel;

4. The hardware failure of the TV causes the volume to fluctuate, such as speaker failure, internal circuit, capacitor failure, motherboard and its parts failure, it is recommended to contact the after-sales service of the TV for a comprehensive inspection and warranty of the TV. Hope it helps.

What's the reason for the TV to suddenly get louder or quieter? Electricity.

1. The volume of the TV is up and down - there is a problem with the input of the signal source. Check whether the TV is in good contact with cable TV, digital TV set-top box, *** machine and other equipment, if it is loose and the contact is poor, the sound may be loud and small. 2. The volume of the TV is up and down - the remote control or button panel is short-circuited or leakage, check whether it is the TV remote control or the button panel short-circuit, the volume adjustment caused by leakage is abnormal, if this is the reason, it can generally be solved by replacing the remote control.

3. The volume of the TV is up and down - whether there is a problem with the program source of the program channel If the program source itself has the problem of volume fluctuation, it can generally be solved by switching the program channel.
