Monitor Not Receiving Signal

I have not used this computer in about a year, and when I turned it on, the monitor remains black and says it does not receive a signal. The power button then goes from blue to orange. I have made sure all the plugs are secured and have tried removing the small metal coin-like item inside of it for a few minutes as others have suggested.

    Never mind, fixed it by removing my RAM.

There is a number of things that could be bad. First is the cable between the monitor and the computer and since you said you checked all of the cable connections we can skip that. Next if you have a separate VGA board installed it may have come loose or may have gone bad. Next is that if your VGA port is built onboard the mother board it may have gone bad and in either case buying a seperate VGA card should fix the problem.

SOURCE: No Video Signal

If you can't use the onboard video and it does POST or the PCI-E video card does show anything, most likely the motherboard is toasted. Apparenty gateway uses real poor quality power supplie and motherboards.

I have the same system, it powers on, but nothing. All I can assume is that the motherboard is bad.

Try resetting the bios. On the motherboard there is a battery that looks like a watch battery. Remove the battery, then replace it again. (make sure the computer is unplugged from the wall socket when you do this)

Does this work?

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.

Display will not come up, screen remains black, blue light on front of monitor flashes on and off
Check that the monitor is still receiving a signal it could have gone into standby mode.
If not you either have a faulty inverter or the back light has gone, to test this when your computer is on is to check you can still see a faint image on the screen that means the backlight has gone, if not its the inverter.

Acer al1716 monitor flicks green and orange and screen remains black
I would say that is not receiving a signal from your computer.
Can you swap out monitors to see if another one works?

Most probably, if you see no error messages at all, you have a bad video card (assuming the computer is actually starting up).

Monitor shows picture for 1/2 second then goes black, 22" display. also will not show display menus. have hooked another monitor up and works fine. also have hooked up to another computor and problem...
When you switch the monitors, do you still use the very same vga cable? If you don't, then it's time to change the monitor. When it turns on and off inmediately it means that it's receiving the signal, but that's it. If it's brand new, exchange it.

I have a 15 inch dell monitor that will turn on then go immediatly black. if i turn the power off then on again it will turn on and then go black again? please help.
Hi, do you have another monitor you can test with? That behavior is normal when the monitor isn't receiving a signal from the cable or video card. The easiest way to test this would be to connect a different monitor to the same cable and see if it works.

Dell172fpb 17" monitor
Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks

HP desktop monitor problem
hi try this ,,,
  1. Ensure the video cable is connected (and connected to the correct video port).
  2. Turn off the monitor using the monitor's power button and then restart the monitor.
  3. Cycle the power on the monitor as follows:
  4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
  5. Unplug the power cord.
  6. Wait 5 seconds.
  7. Plug in the power cord.
  8. Press the power button on the monitor to turn on the monitor. One of two things happens:
    1. The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2. The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
    3. Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
      • If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
      • If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
      hope it will work for u .. little_angel

Acer Monitor Doesn't Receive Signal From Computer
can you test your monitor on another computer to verify the monitor is at fault? If the monitor is at fault its time for a new one, factory warranties on monitors are usually 1 year unless you purchased an extended warranty.Otherwise repair is usually more costly than buying a new one.

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.
