The monitor crashes when it has a zizz sound

Could it be that the voltage in your home is unstable?

There are several reasons why a computer monitor is making a sizzling sound:

Power adapter issues: There may be a problem with your monitor's power adapter, causing the current to be unstable, resulting in a sizzling sound. You can try replacing the power adapter and see if that solves the problem.

Electromagnetic interference: There may be electromagnetic interference around the display, such as other electronic devices, power lines, etc. Try adjusting the position of your monitor away from potentially distracting devices to see if that eliminates the noise.

Faulty components inside the display: Faulty components such as capacitors and transformers inside the display may be faulty, resulting in a simmering sound. In this case, it is necessary to contact professional maintenance personnel for inspection and repair.

Signal cable problem: There may be a problem with the signal cable connecting the monitor to the computer, which can cause the signal to be transmitted unsteadily, resulting in a sizzling sound. You can try replacing the signal cable to see if that solves the problem.

Problems with display settings: The brightness, contrast, and other settings of the display may be too high, resulting in a buzzing sound. Try adjusting your monitor's settings to see if that eliminates the sizzle. and acres.

Display deterioration: Displays that have been used for a long time may experience deterioration, resulting in sizzling sounds. If all else fails, you may need to consider replacing your monitor with a new one.

1. The display screen is dim, and the screen is black at the end, and there is a "squeak" sound inside the monitor, which is indeed the fault of the display itself, and the fault location is:

1. The rectifier diode of the switching power supply part of the (display) is reversed to breakdown, or the filter capacitor is seriously leakaged; The characteristic of this type of fault is that after the black screen, the display indicator flashes and the brightness is very low, and even the indicator light will go off when the fault is serious;

2. In the power supply circuit of the high-voltage board, the black screen is caused by damage to the power tube or serious leakage of the filter capacitor; This type of failure is characterized by the fact that after the black screen, the indicator light (of the display) stays on, or the brightness decreases slightly;

3. The step-up transformer on the high-voltage board is short-circuited between the secondary turns; The condition of the indicator for such a fault is basically the same as in clause 2;

2. The specific methods for distinguishing the articles in the preceding paragraph are as follows:

1. If the "squeak" sound is emitted by a 3 cm square transducer in the power supply part of the (display), the fault is judged to be the first item;

2. If the sound is emitted by the transformer on the high-voltage board, the fault is judged to be Article 3 of the first item;

3. According to the size and frequency of the sound, the specific part of the sound can also be determined, but this requires a strong basic knowledge, so I will not repeat it here.

If this happens, it's usually because of a problem with the monitor. Because you can find that the display is sizzling to prove that there are some components in the display There is a problem, at this time you should immediately turn off the computer and the monitor, and then find someone to test the monitor, if it is a problem with the monitor, you need to replace the monitor, do not work with electricity, otherwise it is easy to cause a fire.

It may be current interference, whether there are high-power electrical appliances around the computer, etc.

If your computer is running, but the monitor suddenly goes black and squeaks, then it is likely that the monitor's high-voltage board is malfunctioning, and you will have to fix the monitor.

1. In this case, most of the display power board is faulty. I will, disassemble the capacitor on the power strip and check it, and replace it.

2. No, you can only send it for repair.

In your case, your computer monitor may be in a state where it is no longer usable, and it is best to call someone to see it.

Take a look at a different monitor. If the computer can be turned on normally, it means that the monitor is faulty, and the monitor is felt. It's going to break.
