I have a desktop monitor. Once i turn on the monitor it stays lit for 2 seconds then goes black. The light stay on. I then touch the power button on the monitor to turn it off. I then repress the power button to turn it on. It displays the desktop then goes black again. I have tryed this monitor on multiple towers and still the same issue. The funny thing is that when the screen goes black the power button light is still green. not amber as if it were hibernating. What do you think?

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

Ok, same issue here as well. Monitor would come on for 1/2 second and then the backlighting will go off. It's next to impossible to tell, but if you shine a bright flashlight at the screen, you can make out the video signal/desktop.

I have now replaced all the Capacitors except the very large one (didn't come with the kit that was available.) None of my caps looked bad (bulging) including the large one. Unfortunately, I still habe the same issue

So my question is....large capacitor replacement or something else?

check the power supply and rem or proccesor

I had the same problem with this monitor (Samsung 943nw)
When turned on it would only stay on for less then a full second.
When shining a light on the screen I could see what was on it, so it was just the backlight that was shutting down.

After I turned down the brightness of the monitor, the next time I powered on the screen the backlight stayed lit and it was back to normal.

make sure monitor is vented properly and not overheating.

Make sure you have the plug in tight or maybe your need a new monitor

reinstall windows ur screen resolution is not accepted by monitor

Same problem here. Does anybody have an answer?
