Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Step 1: Attach LCD screen to another known-working computer (keep in mind to plug into a reliable powerstrip). Check to see if the process can be repeated. If not, then check your computer settings (Power management, etc.). If the issue can be duplicated, then..you, my friend, are experiencing an inverter failure. OK. Moving on. Buy and inverter and replace it. Not a good option for you? Might as well get a new unit. You missed several Black Friday deals but hey, some are still on sale tomorrow.

My AOC screen goes black after about a few seconds after booting.


Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

My screen goes black after a few seconds


Sounds like a bad solder joint on the printed circuit board. Once it heats up then it no longer makes good contact and the monitor goes black until it cools down and makes contact again. You could resolder it if you knew where it was but monitors are dangerous to go playing around with as they can hold very high charges of electricity in their capacitors that are very dangerous. It's a throw away world. Go buy a new one.

Lcd monitor goes black


Try a different monitor (a friend's) on your computer, if it works OK the problem may be with your monitor. If it does the same as on your monitor, the computer video card may be defective.

Try your monitor on a different computer (a friend's) etc. You will figure if anything or what is defective. Then you can decide to repair or replace.

No picture on my x5g-komodo7 monitor


A reddish picture is the classic symptom of worn out backlight bulbs.
Sensor circuits usually shut down the power to the bulbs in a second or so.

Screen not lighting up and staying black.


if the green light is always on that means there is no prob concerning the power and the monitor itself. the problem seems to be coming from your graphic card..
try with another graphic card..

OR
you might not configure the screen resolution to the appropriate level..
can you run your pc correctly in safe mode??

Monitor show picture for a few seconds, then turns black


It sounds like the power supply board on your monitor is failing. If it's still under warranty you might be able to get a replacement from the manufacturer - if not, you might be able to have it repaired at a computer or TV repair shop.

Screen goes black


I recently had a similar problem with a MAG LCD monitor. Try the following to see if this resolves your problem: - set brightness to a lower level. On LCD monitors you can go as low as 0 and still see the screen. With my problem when I set the brightness below 70% the problem went away. A few days later I turned it all the way up to 100% and the problem did not return. However I did not continue to keep it at that level. I found no need for it and find 50% to be exceptable for my needs. I would say yes it does have something to do with the lamp controler which controls the lamp brightness. I do not know all the technical reasons why a controler starts to have this sort of problem. If your monitor is still under warranty I would take advantage of the free repair otherwise keep the brightness below the level that causes the problem; for me that was under 70 percent. I hope this solution works for you. Perhaps there are others that can give you all the technical reasons why a controler starts to exhibit this behavior. Sincerely, Dean Kenneth Robinson
