When we use the computer, sometimes the lcd display of the computer monitor is not normal. What should we do when we encounter such a problem? There are two possibilities for this phenomenon, one is the failure of the display high-voltage board, and the other is the failure of the display lamp. 

1. Fault of lcd display high-voltage board. 

If you have a voltmeter and you know how to use it, you can disassemble the monitor and measure whether the voltage of the lamp output from the high voltage board to the screen is normal. The working voltage varies depending on the type of screen, and the LED screen is basically 30 to 55V. After confirming that it is the fault of the high-pressure plate, the further analysis is a bit professional, and electronic parts are needed for repair. if you do not have the conditions, it is recommended to buy a general-purpose high-pressure board for replacement, the price should be about 50 yuan. 

2. The lamp tube of the lcd display screen is out of order. 

Troubleshoot the high-voltage board, then only the lamp of the display screen. The lamp can not be repaired, it can only be changed. Can go to the repair shop to see if there is a change, if the repair shop does not have the same type of lamp change, then can only change the display screen. There is a model written on the back of the display screen, which can be replaced by going to the electronic mall or online. 

If your computer monitor is under warranty, you can directly seek after-sales service, do not repair it yourself, otherwise there will be no warranty later. 

In addition, if you want to analyze yourself, you will need to dismantle the machine, you can follow the following steps: 

1. First prepare a plastic sheet, such as abandoned bank card, membership card and so on. 

2. Remove all visible screws first. 

3. Insert a card from the frame, then pull down the gap and widen the gap until the entire back shell can be pulled up. 

Note: if you do not have the tools, or lack of hands-on ability, it is recommended to send it directly to the repair shop. Like ordinary computer repair shops, home appliance repair shops can be repaired.
