The TV suddenly couldn t be put on, and after a few days, it was put on

1. Magnetization of the TV.

Causes of magnetization of the TV: The TV has been subjected to severe vibration, the degaussing resistance inside the TV is damaged, the magnetization is affected by the magnetic objects next to it, and the deflection coil or color pure magnetic ring in the TV is displaced.

Magnetization of the TV solution: After the TV is subjected to severe vibration, there will be more situations, and it is not certain whether it is the damage of 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.

2. There is no electricity on the whole TV.

The reason for the lack of power of the whole machine: 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 likely to be damaged are some small components in the machine, which are relatively small, such as: fuses, rectifier bridges, power switches, etc. Another is the failure of the driver board, which causes the whole machine to have no power.

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.

3. There is sound but no image.

Reasons for sound and no picture: The first suspicion is 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.

It's certain that there is something wrong with the machine, but it's hard to say what the problem is! Maintenance personnel can only check step by step when there is a fault, starting from the power supply. In the case of normal release, it is impossible to determine what component is wrong! Of course, it doesn't make much sense to say it.

This is due to the high humidity of the air.

If the air humidity rises, there is dust on the circuit board of the TV, or if it is used for a long time, there will be leakage on a certain amplification component of the high-voltage part of the circuit board, causing the circuit protection of the power supply part, resulting in the failure to turn on. When the air humidity is restored, or when the air humidity is artificially patted, (the dust is removed) can cause the machine to turn on.

If the stability of some components is not good, it may be that the capacitor bar first detects the power supply part.

Caused by poor contact of components in the TV.

Dear,Reference two,What should I do if I can't turn on the TV for a long time,1、The first thing to check is the power supply part,See if the power output is normal。 2、To see whether you are using a black and white TV or a color TV,If it is black and white, you can directly measure the output voltage,But if it is a color TV,The reason is more complicated。 3. First of all, connect a negative pole of the bulb to the ground at the high-voltage output foot of the switching power supply, and open the load section behind to see if the voltage is normal.

5. If you don't do this, you can't measure the normal voltage or the whole TV may burn out. If the measured voltage is normal, it means that the source part of the switching power is good, and other parts of the Yusheng can be checked. 6. The next thing is to check the CPU, the CPU is the place to control the TV switch, if you don't control the CPU, then the TV is naturally impossible to turn on.

7. Test whether the voltage of the three key points of the CPU is normal, if not, find the relevant power supply circuit to see if it is caused by the instability of the power supply circuit.

1. It may be that the TV card is temporarily faulty, please try to unplug the TV and restart it. 2. It may be that the TV remote control or TV switch is faulty. Check if the remote control is damaged, replace the remote control, and try again.

3. It may be that the firmware of the TV system is damaged, and you need to contact the manufacturer to set up a home reset system or a remote command reset system. 4. It may be that the TV display screen is burned out, and it can only be solved by replacing the display screen. 1. Usually, the TV is in standby mode 2113.

You can press the standby button 5261 power button on the remote control to call 4102 to wake up the TV, or press the channel channel-button1653 on the body to wake up the TV. If you can't wake up the TV with the remote, you can press the standby button on the back of the TV to start the TV. 2、If you can't start the TV through the remote control and the standby button behind the TV,You can basically judge that the hardware of the TV is faulty。

Such as short circuit in the internal circuit of the TV, high-voltage packaging failure, picture tube failure, motherboard switch circuit failure or other component damage, etc. This can cause problems that are always on standby. When this happens, it is not recommended that users perform a self-test.

For safety reasons, the manufacturer's service department should be contacted for a comprehensive inspection and warranty of the TV. 3. TVs are related to machine memory function, so the last time it was turned off, the user pressed the standby button of the remote control to make the TV enter the standby state, and the next time it was turned on, the TV will automatically enter the standby state, and the standby button of the remote control needs to be pressed to wake up the TV.
