    There is nothing that can't be done, just be careful and teach you how to change:

    1. Turn off the power of the TV.

    2. Use the table pen of the multimeter (you can also make one) to discharge the high-voltage cap, because after the TV is turned off, there will be some residual high voltage, first connect the metal needle at the short end of the watch pen to the ground wire on the edge of the picture tube, and then hold the plastic part of the watch pen, and insert the watch needle into the high-voltage cap and the picture tube for discharge.

    3. Pull up one side of the high-pressure cap left and right, clamp the spring clip with needle-nose pliers with your right hand, and pull it out obliquely from the side of the high-pressure cap.

    4. Weld off the high-voltage wire and clamp from the high-voltage cap.

    5. Thread the high-voltage wire into the new high-voltage cap and weld it with the clip.

    6. Coat a layer of insulating silicone grease on the circumferential range of 2-3cm on the edge of the high-voltage nozzle of the picture tube to prevent moisture from entering and leaking electricity in the future.

    7. According to the reverse order of removing the high-voltage cap, the high-pressure cap is loaded into one side with the clamp tilt first, and the other side of the clamp is pushed in between the pliers.

    8. Rotate the high-pressure cap left and right and press it to make the clip fully in good contact with the high-pressure nozzle.

    9. After removing the discharged grounding wire, it can be used after checking that it is correct.

    Practice has proved that the tube socket is broken, the high-voltage cap is broken, don't worry, change it, your TV can't store the high voltage.

    A TV that doesn't break the high pressure cap has high voltage.

    It cannot be dismantled casually, there is high pressure.

    In order to reduce the number of AC pulsating ripples and smooth the DC output, the smart TV integrates a filter capacitor on the motherboard, as a capacitor, its biggest feature is the power storage capacity, that is to say, even after the power is off, the power stored in the capacitor is still stored, and once touched by a conductive object (including the human body), it will be released instantly, and after the rectification of the 220V voltage, the voltage at both ends of the filter capacitor is as high as 330V.

    In addition to the filter capacitor, the high-voltage package (line output transformer) in traditional TVs also has the characteristics of power storage, and once touched, it is very likely to be electrocuted. So the TV can't be taken apart without permission.

    Can the TV be disassembled casually, and is there high voltage in the back?

    It cannot be dismantled casually, there is high pressure. In order to reduce the number of AC pulsating ripples, the smart TV integrates a filter capacitor on the motherboard, as a capacitor, its biggest feature lies in the power storage capacity, that is to say, even after the power is off, the amount of electrical disturbance excitation still stored in the capacitor, and once the conductive object (including the human body) touches, it will be released in an instant, and after the rectification of the 220V voltage, the voltage at both ends of the filter capacitor is as high as 330V.

    Hello, I am happy to serve you and give you the following answer: whether the TV high-voltage bridge hat is replaced depends on the cause of the problem. Generally speaking, when the TV does not work properly or the display is not working properly, the high-voltage cap may need to be replaced.

    The high voltage cap of the TV is the core component of the TV, which can adjust the high voltage of the TV to ensure the normal operation of the TV. The reason for the problem of the high voltage cap of the TV may be due to the overload of the TV, or the power supply voltage of the TV is not stable, or the circuit board of the TV is burned. To solve this problem, you first need to identify the cause of the problem.

    If it is due to the overload of the TV, you need to check whether the power supply voltage of the TV is stable; If it is due to the burning of the circuit board of the TV, it is necessary to check whether the circuit of the TV is damaged, and if it is due to the problem of the high pressure cap of the TV, it is necessary to replace the high-voltage cap of the TV. The steps to replace the high-voltage cap of the TV are as follows: 1. Turn off the power, disconnect the power cord, and remove the TV; 2. Find the high-voltage cap of the TV, remove the old high-voltage cap, and install the new high-voltage cap; 3. Put the TV back in its original place, connect the power cord, turn on the power, and test; 4. If the test result is normal, it means that the replacement is successful, otherwise replace the high-voltage cap again.

    Personal tips: 1. When replacing the high-voltage cap of the TV, you must pay attention to the safety of the TV power supply and do not touch the circuit board of the TV. 2. When replacing the high-voltage cap of the TV, pay attention to the operation sequence and do not install the new high-voltage cap upside down.

    3. Replace the electricity.

    Hello, it is a pleasure to serve you and give you the following answer: whether the high voltage cap of the TV is replaced or not depends on whether it is faulty. If the TV fails, the high-voltage cap may need to be replaced.

    Generally speaking, there are several reasons for the failure of the high voltage cap of the TV:1The circuit board inside the TV is faulty, causing the TV to not work properly; 2.

    The capacitor inside the TV is faulty, causing the TV to not work properly; 3.The electronic components inside the TV have a side width failure, resulting in the TV not working normally; 4.The power cord inside the TV is faulty, causing the TV to not work properly; 5.

    The high-voltage cap inside the TV is faulty, causing the TV to not work properly. If the TV fails, the high-voltage cap may need to be replaced. The steps to replace the high-pressure cap are as follows:

    1.Turn off the power and disconnect the power cord; 2.Open the case of the TV and find the high-pressure cap; 3.

    Unscrew the high-pressure cap by hand; 4.Remove the old high-pressure cap and install a new one; 5.Tighten the new high-pressure cap; 6.

    Close the TV case and reconnect the power cord; 7.Turn on the power of Luliang and check if the TV is working properly. When replacing the high-pressure cap, the following points should be noted:

    1.When replacing the high-voltage cap, the power supply should be disconnected first to avoid electric shock; 2.When replacing the high-voltage cap, you should pay attention to tightening the high-voltage cap to avoid the failure of the TV; 3.

    When replacing the high-voltage cap, you should pay attention to check whether the TV is working properly to avoid malfunction. That's all about TV.

    The high-voltage cap of the TV socks is soldered on the circuit board of the TV,Disassembly and replacement need to be achieved with an electric soldering iron and a hollow needle,Replace all the pins with a new high-voltage package,Then solder the circuit board pins to complete,The specific operation steps are as follows:

    1. Use an electric soldering iron and a hollow needle to remove the solder.

    2. Remove all the pins in a circle.

    3. The high-pressure package can be removed by pulling it outward.

    4. Insert the new high-voltage package pin into the hole.

    5. Make the game suspect soldered with a solder electric soldering iron.
