Does the old TV at home make tinnitus like noise as soon as it is turned on Does it have an impact o

Hello! This kind of problem is generally the following local problems:

1.The core of the power transformer is loose.

2.The high-voltage clad core is loose.

3.The deflection coil core is loose.

4.The core of the pillow coil is loose.

5.Other transformer cores are loose!

Open the TV case and see if you can hear which core is making the sound! Then use insulating paint to pour dry and solidify for two days, if you really can't hear it, then you can only pour paint one by one! This kind of failure has stumped many of our masters!

There are also some masters who can't hear the voice, you say there is a voice, and he can't hear the master he bumps into, he says there is no sound! Hehe, what a hassle! If you can't find out, paint the transformers with magnetic cores one by one, and they will definitely be cured!

I've fixed dozens of these problems! It's just quite annoying, but it doesn't have any effect on health!

If LZ is worried about the harm of ultrasonic infrasound, it is not necessary, because these two kinds of sound people can't hear, the sound of the TV at home is due to the aging of the TV picture tube, and the sound generated when the current passes through the picture tube, it can also be regarded as noise. After listening to it for a long time, it really becomes tinnitus.

It is inevitable that there will be an impact, and it is similar to noise, but it is really not possible to change it to a new one! If you are reluctant to change it, send it for repair.

I don't know if it has any effect on the body.

But there must be something wrong with your TV.

Since the old TV is broken again, let's replace it.

1. The TV is damp, and the internal high-voltage packaging leakage produces different cracks and electromagnetic interference. Running the TV in this state will produce a lot of noise, and it is recommended to fix it as soon as possible, and it will have a certain impact on the display screen if the TV is sold in this state for a long time. 2. It may be that the audio connection between the TV and the set-top box is faulty, and it can be replugged or replaced.

There is a noise solution for the TV.

1. If the TV makes a sharp sound, you can switch the TV to silent mode first. If the noise does not go away, it may be that the transformer core is loose. At this point, you must consult a professional to help solve the problem.

You can't move at will to avoid bigger losses.

2. You can tell whether the noise of the TV is coming from the speaker or from inside the TV. If the noise coming from the speakers is not a problem with the live source, it is very likely that there is a problem with the AFC of the TV, and the situation must be left to a technical professional.

Generally, the so-called high-frequency noise is emitted by the switching transformer, line push transformer, line output transformer and some high-frequency coils inside the TV, and its frequency is generally the line oscillation frequency 15625hz, which is near the upper limit of the general human ear's hearing, many people are very insensitive to the sound of this frequency or even have no feeling at all, but there are also some people who can not only hear but also feel very harsh. Under normal circumstances, the TV should not produce this kind of noise, the reason for its occurrence is that the core of some transformers or coils is loose, the solution is not complicated, as long as the back cover of the TV is opened, turn on the power to make the TV work (it doesn't matter whether it is connected to the signal source or not), carefully identify the location where the noise occurs, and touch the transformer or coil in question with a screwdriver after preliminary determination, this contact will change the noise generation conditions and make it disappear or enhanced, when the transformer or coil that produces noise is fully confirmed, If you are concerned about the inconvenience of future maintenance, it is recommended not to use 502 glue or epoxy curing adhesive, you can use 704 glue and other soft glue, for the transformer or coil with little heat, you can even pour paraffin wax or ordinary candles, this method is very effective for solving such problems, but if you do not have the most basic home appliance maintenance skills, it is recommended to ask experts to help solve it.

After the TV is turned on, it will emit a "ziz" noise, which belongs to the high-voltage cap aging and ignition due to moisture.

Remove the high-pressure cap, wipe the area with a diameter of 12cm at the high-pressure nozzle with an anhydrous alcohol cotton ball, dry it with a hair dryer, and replace it with a new high-pressure cap. They should not be left to work, and they must be dealt with before watching TV, so as not to endanger the picture tube and circuitry.

Have a nice day!

That's the problem with the CRT high-pressure pack, and if you get closer to the back of the TV, you can see the blue-purple light and you can smell a smell, hehe, this smell is ozone.

A different high-pressure package will do.

The main reasons: 1. The TV is damp and thicket, and the leakage of the internal high-voltage package produces peculiar smell and electromagnetic interference. Running the TV in this state will produce a lot of noise, it is recommended to fix it as soon as possible, and it will have a certain impact on the display screen if it is used in this state for a long time.

There is a noise solution for the TV.

1. If the TV makes a sharp sound, you can first switch the TV to mute mode. If the noise does not go away, it may be that the transformer core is loose. At this point, you must consult a professional to help solve the problem.

You can't move at will to avoid bigger losses.

2. You can tell whether the noise of the TV is coming from the speaker or from inside the TV. If the noise coming from the speakers is not a problem with the live source, it is very likely that there is a problem with the AFC of the TV, and the situation must be left to a technical professional to solve the problem.

1. Reasons: 1. The internal circuit of the TV is overloaded or the transformer core is not firmly glued, resulting in the inductance or the core of the transformer vibrating and making a sound;

2. The internal circuit of the TV is damp and leakage, and the high-voltage package makes a sound;

3. The sound of the internal circuit of the TV high-voltage package sparking;

4. The sound of the leakage of the base of the picture tube is well covered by the TV set;

Second, the treatment method:

1. If the sound is not loud and does not affect the normal use, then there is no need to pay attention to it, if the situation seriously affects the use, it is recommended to contact the after-sales service of the TV for comprehensive testing and warranty of the TV.

2. When there is an abnormal sound or smell in the socks, please turn off the power and unplug it immediately.

3. Open the back cover of the TV, turn on the power to make the TV work (it doesn't matter if you connect the signal source or not), carefully identify the part where the noise occurs, and touch the transformer or coil in question with a screwdriver after preliminary determination, this touch will change the noise generation conditions and make it disappear or enhanced. When the transformer or coil that is causing the noise is fully identified, it can be loosened and fixed by pouring adhesive into the core of the transformer or coil.
