It can be turned on, the screen is not displayed, and it keeps ringing, what is the reason?

If it keeps ringing, it may be a fault of the memory or graphics card, it is recommended to unplug the memory and graphics card, clean the gold finger, and then plug it in to see.

PS: Some machines will also have a long beeping alarm if the keyboard is broken.

One is long, and the other is loose memory.

One long and three short is the graphics card is loose.

Just pull them out and wipe them separately.

Problem description: My monitor is a MeiG 796FDII that left the factory in January in 03, and the display effect is very good. But recently I found that there was a strange phenomenon: the night before yesterday when the shutdown was normal, the next morning the dormitory at 6:30 called, I heard the sound of air leakage in the monitor, but pressed the power button did not respond, had to turn off the power!

Now there is still this kind of selling problem in the scrambling cover,That is, the display is powered on but can't be turned on normally,It takes two minutes to wait for the power on,That is, the sound in the display lasts for two minutes before the display can be turned on,At this time, the sound of air leakage is gone,The display can be used normally,What is going on?

ps:There is another thing that happened at the same time as this incident,I changed a new speaker and put it on the top of the computer desk,It is directly above the monitor,The upper half of the screen of the monitor began to shake,Today the speaker is removed with the same,The jitter disappears,Only to find out that the original jitter was caused by the magnetic field,I don't know if the sound has anything to do with this?

I've gotten to the computer city and the guy there changed the relay for me, but now the problem persists.

Analysis: If there is a problem with the high-voltage package, there will be a fault as you said, and it will cost about 100 yuan to change the high-voltage package (Chengdu, New Century Computer City, direct maintenance fee).

As for whether this will be the case for other issues, I don't know.

Generally, the memory module is not well plugged in.

Does Dididi's sound continue to ring or does it stop ringing for a while? If it is continuous, it is recommended to try to change it with a memory module, I hope it can help you!

The dust of the chassis is cleaned up, pull out the memory module, wipe it with the gold finger of the eraser, memory, and re-plug the hardware to start the hardware for start-up, and it is recommended that the maintenance station detect and repair.

Use a hair dryer to blow hot air everywhere, blow the dust away and blow the parts hot, mine can't be turned on in cold weather, maybe the machine is too cold, just like our motorcycle is difficult to start in cold weather, mine is successful in this way.

Upstairs, the screen doesn't show how to enter safe mode or reinstall the system
