LCD monitor power supply high voltage integrated board, the high voltage board is burned, how to connect the high voltage board wire, please help me, please give me some details?

The high-voltage board of the high-voltage integrated board of the LCD power supply was burned out, resulting in unclear line connections. In response to this situation, PHP editor Zimo will provide an in-depth analysis of the high-voltage board line connection method to help everyone solve this problem. The following details will provide you with a clear and comprehensive guide to help you successfully repair your LCD monitor.

The LCD power supply high voltage integrated board, the high voltage board is burned, how to connect the high voltage board wire, please help me, please give me some details?

Remove the high-voltage part of the original power board, install the new high-voltage strip, and connect the power supply, screen backlight signal (BLON), brightness adjustment (ADJ), and lamp circuit.

The 12v voltage of the new high-voltage bar is connected to the 12v of the original power board. The other two control signal screen backlight signals (BLON) from the driver board are for power on and off control, and the brightness adjustment (ADJ) is for adjusting the brightness of the backlight. , dark one, connect it to the corresponding interface of the new high-voltage bar, and then plug in the light pipe line.

Because its working principle is to convert low DC voltage into high AC voltage, it is commonly known as "high voltage bar" or "high voltage plate".

I have a monitor here, and I want to change the high-voltage strip. The wiring plug is marked like this, 12v GND 5V BL-ADJ BL-EN. Can you guys see how to connect it?

12 Connect the positive pole of the power supply to GND, which means grounding. That means the negative pole of the power supply is 5V. Connect the positive pole of the power supply to 5V. The switch is EN. The brightness adjustment ADJ is OK. If it is not the original high-voltage strip, you only need 3 wires. The positive and negative poles of the power supply are connected to the ground. Switch signal

How to connect the high voltage board of computer monitor to the screen?

The wiring method is as follows: Replace the high-voltage board with the same interface as the high-voltage board, and turn on the TV to check whether there is an image. If the image is displayed normally, it means there is no problem with the high-voltage board. If it still cannot be displayed, the high-voltage board may be damaged and needs to be replaced with a new one. After confirming that there is no problem with the high-voltage board, connect the connecting cable between the high-voltage board and the screen. Tighten the fixing screws on the screen and check whether there is any leakage. After completing the wiring, turn on the TV and see if there is an image displayed. If everything is normal, the wiring is successful. Note: Be sure to pay attention to safety when wiring and do not touch high-voltage parts.

How to wire the monitor high-voltage light strip?

Hello, generally speaking, the wiring method of the high-voltage light bar of the monitor is as follows:

1. First, determine the positive and negative poles of the high-voltage light bar. Generally speaking, the two terminals of the high-voltage light bar There will be marks on the terminals, one terminal is the positive terminal and the other terminal is the negative terminal.

2. Connect the positive pole of the high-voltage light strip to the positive pole of the high-voltage driver board, usually through pins or plugs.

3. Connect the negative pole of the high-voltage light strip to the negative pole of the high-voltage driver board, also through pins or plugs.

4. Finally, connect the high-voltage driver board to the monitor motherboard, thus completing the wiring of the high-voltage light strip.

It should be noted that the wiring of high-voltage light strips must be careful, because the voltage of high-voltage light strips is very high, and improper wiring may lead to dangerous situations such as electric shock. Therefore, before wiring, you must first understand the wiring method of high-voltage light strips, and be sure to do it in a power-off state. If you're not sure what you're doing, it's best to call in a professional.

How to connect the wires of the high-voltage power supply board of the display screen?

The steps for wiring the display high-voltage power board are as follows:

The three wires are: 12v, control signal, and ground wire. The 12v, ground wire is connected to the 12v, ground wire on the power board. The control signal line can be seen jumping from the om/off of the driver board to the port on the power supply board.

There are usually only four incoming wires to the high-voltage board (not counting parallel wires). The two wires coming from the control panel are adj and on/off. If they are connected inversely, they will not light up and will not burn anything. First check whether the voltages are normal. Normally just change the high voltage board.

First find the connecting wires between the power board and the high-voltage board. Generally, there must be power supply, ground wire, switch, and brightness adjustment. Correspond to the four wires on the universal high-voltage board. Then connect the high-voltage part of the power supply high-voltage integrated version. disconnect.
