Lcd back light shuts off but monitor is still on and receiving signal. Power off and back on will restore back light for about 30 seconds. Also the last few times I turn it on, the screen has become a white-out with lines when the back light does light.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


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.

Recently when I boot up my computer I get the monitor to display an image for about 2 seconds and then it goes to a black screen. if I unplug the monitor from the back of the computer and plug it back in,...


The capacitors for the power source are failing. This causes a short burst of power to get to the lamps, but then they cannot hold a charge to continuously power the lamps. You will have to replace the monitor. I suggest checking your warranty status and replacing the monitor.

Have signal, but no light, just one second screen can see and shut off.


Please clarify by shut off you mean power light turn off or just screen gone blank but power light remain on!

Mostly inverter(power supply) needs attention in such cases.

My NIKO 1906W-R LCD monitor starts, but the picture goes off in about a second. The monitor shows the green light indicating it's receiving a signal. I'm looking for a service manual before opening it up....


There are two boards that need to be checked, the power supply board is one problem area "often bad capacitors that bulge at the top" the second problem area is the inverter board and often has bad capacitors, it powers the back lights.

Hi i have a problem about my lcd viewsonic va702, when starting my computer i can see the image for 1 sec then it turn black ...lcd light is ok and computer too already tried with other lcd all works fine...


this works for Dell monitors with a similar problem: shut down, turn off monitor and pc, turn off at wall socket, and remove power plugs from wall socket. wait about 30 seconds. plug back in, turn on, and all should be well? I have used this 3 times on a Dell PC with a Viewsonic monitor.

Monitor screen begins as computer is booting up and then screen goes black. Message says there is no signal.


If the power light dims or changes color after the no signal message comes up, that means the monitor went to sleep.
While the monitor is plugged in and on and the computer is also on, Try unplugging the VGA cable from the monitor. wait 30 seconds and then plug it back in o see if the power button light comes back to normal color and the screen flashes on.
If not, then the monitor is not getting a signal from the computer.
If using a desktop computer,Try a different cord or try the monitor on another computer.
If using a laptop, you need to activate the laptop to use an external monitor. That can be done through the display settings, OR, most laptops have a shortcut key feature which usually involves pushing the Fn key and one of the F keys at the same time. The F key may say CRT/lcd or have a picture of a monitor and a screen.
If the power light does light back up and still no picture, There may be an internal issue on the monitor

(Example 1000uf 16v ) if you are lucky you can spot it right away...with a bulged on top of each caps. If not, just replaced all of the caps... Good luck!

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.

Monitor has no picture


Yes! :)

Your monitor is not the problem. Check all the connections from the back of the monitor, to the computer.

"No Signal Analog" means your monitor is working perfectly, however is not receiving signal from the computer.

Didnt find any loose cables?
Try unplugging everything. Leave it unplugged for at least 5 minutes. You need to give the system time to drain all the excess power.

Again your monitor is fine, blue light > No signal > orange light is totally normal for your montior.
