Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

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.

First to check will be the power supply, look for bad caps with bulging tops first then report back so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

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.

Screen goes black, but power light is on (not blinking)


The problem is not with your screen. Its the problem of Video Card of your system which is unable to send Video Signals to the Screen.

Starlogic 20 inch widescreen monitor screen keeps going black


This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.

If you don't see an image with the flash light, then it could be the main logic board.

Monitor black screen


Your first step in troubleshooting this problem is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is shot.
