The TV is out of order, ask for advice, the TV is out of order

No, most likely it is a field output failure.

It may be due to the fact that the TV has been damaged by ** and the wiring inside has been damaged. It could also be that the TV's motor is broken. It may also be that the screen picture tube of the TV is broken, and you can find a master to repair it, or replace it with a new one.

1. First of all, check whether the power plug of the TV cannot be contacted. If the contact is bad, plug it back in. Secondly, check whether the screen picture tube of the TV is burned out.

If it burns out, you need to replace it with a new picture tube. Use a voltmeter to check if the voltage of the power supply is too low. If it is too low, a voltage regulator will need to be installed.

2. Check whether the motor of the TV is burned out. If it burns out, you need to replace it with a new one. If the TV has encountered ** recently, then the lines in the TV will be disconnected. At this time, it is necessary to re-weld.

3. Check whether the TV screen has been flooded recently, or the outside of the screen has been impacted. Check to see if the screen is showing deterioration. If the TV screen is damaged, then the TV screen needs to be replaced. If the cost of replacement is too high, replace it with a new TV.

4. Avoid sleepiness in daily use of the TV and some high-power electrical appliances to use a power socket, which will cause the voltage of the TV to be low. Try to avoid TV collisions and keep the TV in good heat. When wiping the TV screen, use a cloth moistened with a small amount of water.

Wait for it to air dry before turning on the TV.

Pro, common fault one: TV magnetization TV magnetization causes: TV has been subjected to severe vibration, the degaussing resistance inside the TV is damaged, affected by the magnetization of the magnetic object next to it, the deflection coil or color pure magnetic ring in the TV is displaced TV magnetization solution:

There are more cases of TV sets that have been shaken by dramas or pailie, and it is not certain whether it is the damage to the components or human factors. If the picture can be displayed, except for the halo phenomenon of the screen, everything is normal, then it can be solved with a professional degausser. If it can't be solved, it is generally that the degaussing element inside is damaged, and the component should be replaced.

Be careful not to place magnetic objects next to the TV, as this will have a big impact on the TV. There is also a color system that has not been adjusted well, so you can adjust it yourself. Common fault two:

There is no electricity in the whole TV The reason why the whole machine has no electricity: This is a very simple fault, which is mainly caused by the internal power supply and the external power supply of the TV. Generally, the failure rate of the external power supply will be higher.

What is more easily damaged is some small components in the machine, which are relatively cheap, such as: fuses, rectifier bridges, power switches, etc. There is also a failure of the drive code group ballast plate, which leads to no power in the whole machine.

The whole machine has no power to solve: if it is the cause of the power part, it is relatively simple to overhaul, and the problem can be solved after replacing these parts. If it is a fault of the driver board, it is a little more complicated, to check whether the relevant voltage of the power supply is normal, the failure of the driver board will cause the two groups of power supplies to have no output voltage, as long as the voltage is problematic, the driver board must be a problem.

Common fault 3: There is sound but no image Reason: First of all, it is suspected that there is a problem with the high-frequency head, which will directly lead to this situation.

There is also the color system is not adjusted to the pair, and the brightness is not adjusted to come out, and the color system is checked by adjusting the remote control. After the high-frequency head is damaged, there is no image input, so there is no image display on the TV screen, check whether the relevant parameters of the high-frequency head are normal, and then replace.

Then there is the adjustment of the color system of the TV, which is also one of the reasons, but this is usually relatively rare. When the TV is turned off, you can see the light of the TV at the moment of turning it off, and there is a little discharge sound, then it can be concluded that the picture tube of the TV is normal. The above are the causes of frequent failures and corresponding solutions when using TVs, have you understood?

If you also encounter the same problem when you are **TV,Then hurry up and take a look at the reasons for the failure of the TV and the corresponding solutions,I believe that through the above introduction,You will be able to quickly solve the failure of the TV,Let us enjoy the experience brought to us by the TV more smoothly,Hurry up and find out。

Common fault 1: Magnetization of the TV Causes of the magnetization of the TV: The TV has been subjected to severe vibration, the degaussing resistance of the TV is damaged, the magnetization of the magnetic object next to it, and the deflection coil or color in the TV.

Common reasons for which obstacle two: the whole TV has no power The whole machine has no power Reason: This is a very simple fault, mainly caused by the internal power supply and external power supply of the TV.

Generally, the failure rate of the external power supply will be.

A television is a very complex electronic device. The following introduces several common faults of TVs and how to deal with them for the reference of electronics enthusiasts.

1. Pigmentation This is a common fault of color TV, generally a fault of the degaussing circuit.

2. No light and no sound The power supply circuit and line scan circuit should be checked. You can first measure whether the main DC voltage output is normal, if it is very low, the line load can be disconnected, and then measure this voltage, if it returns to normal, it means that the fault is in the line scan circuit, otherwise the fault is in the power supply circuit.

3. A vertical bright line appears on the screen This fault is only limited to the line scan circuit.

4. A horizontal bright line appears on the screen This fault is only limited to the field scanning circuit.

5. The white fog on the screen is generally the deterioration of the picture tube base.

The high-pressure nozzle should be cleaned and then sealed with silicone after replacing the high-pressure cap, which has certain hazards to the CRT and should be dealt with in time.

Is it red or blue fire? Generally, the high-pressure cap is a blue spark when it is ignited by moisture, accompanied by a strong ozone smell. If there is a red flash, it is necessary to consider the failure of the CRT filament.

Generally speaking, you have to charge a door-to-door fee when you come to the door, after all, do people also run away?

Generally speaking, the relationship between the CRT TV and the CRT is not very large,At the beginning, you should see if there is high voltage on the screen (you can feel it with your hands,There is static electricity)Then whether the high voltage can continue,Then see if there is a little light in the tail behind the picture tube (filament works),Then see if the voltage on the tail grab is normal。

In short, if you don't check carefully, it's impossible to make a judgment right away.

Now there are not many maintenance workers who really have the ability, and a lot of **repair shops will**stay, many people are not very good in the miscellaneous repair shops outside, most of the washing machines, old refrigerators, products with simple circuits can still be repaired, and the circuit of TV is very rich, and our basic simple faults are OK, and complex ones are generally not.

I suggest that you still find the original brand of repair station, they have a way to repair it, but the cost is still not low, after all, people are also service.

If you feel that the maintenance fee of 200-400 yuan (which may not include the cost of components) is too high, then buy a new one, supermarkets have cheap picture tubes and liquid crystals.

No, the possibility of the CRT is very small, and this phenomenon is not like the CRT is broken, and the CRT will not be broken for no reason, I'm afraid that he will be damaged in the process of repairing, you don't understand, you can only say what he says, are you sure he has passed the craft? Don't be fooled, if it's really a picture tube, I suggest you don't change it, it's been 10 years, and there is no value in changing the picture tube.
