    hi i have the same problem. no signal going to my monitor.
    heres what i have done so far.
    i have tried using same model PSU as a replacement, and still no signal to monitor.
    HD is okay, PSU is okay. now, when i turn it on, chipset fan turns on, HD runs, almost everything is normal.. but no signal is going to my monitor..
    i have tried using a different monitor already, different HD, d/c'd connectors on HD, optical, floppy, one at a time, still.. no beeps to at least give me an idea what the problem is.

The 2 extra wires will most probably be temperature sensors.
If your using the onboard video, then make sure you have memory in the first DIMM slot (it will say DIMM1 beside it)

If that dosn't solve the problem then try these:

  • Remove the memory and reseat it. Make sure to put it back in the correct way. There is a notch towards one end that will match the notch of the memory slot. Press it in until the 2 clips lock fully, then give it a gentle wiggle side to side while pushing down still.
  • Listen to the beeps your computer makes when starting up. A single short beep is what you want to hear. If you hear. If you hear something else then post back what it does. There are long and short beeps that could be involved.
  • Disconnect all the IDE cables from the back of the drives. You can leave the power cables connected. When they go back in they also have a notch and can only go in one way.
Try those for a start and post any progress you make. Also just double check the video cable is correctly attached at both ends to the computer and to the monitor.

Hi. My Acer monitor AL2216W goes black just seconds after turning on. It's still on. Indicator light is green not amber or off. I keep it updated. It's a 2007. My pc a 2008 Del. Suggestions?

well you can test the monitor an any PC made, to see if the problem is the monitor .
easy no? just one simple test. I guess a VGA cable.
That old monitor uses CCFL back lamps. that most at dead now.
after 10 years of service they are DEAD. most are. now.
Green means not sleeping.
when PC goes offline the Monitor tells you ,
lost signal, going to sleep, no sync, or out of range.
all monitors made 2000 to now do that. every one.
the OSD dead. test.
so when you turn the monitor on , and push menu button
in under 5 seconds, does the monitor show the OSD screen.?
it will do that even if PC is turned off.

The OSD is the tiny brain in the monitor. on screen display.
if you test the monitor with a flash light when it goes black with
PC on.
and you see data, that means the CCLF are dead.
the do that, all do this now. dead, intermittent, stobes, or yellow for white screens. all do that at 20,000 hours. used.

click flashlight link here.

value if the monitor is $20 working , or $5 not.
so repairs are not all that econ101 giving this fact.

Have an xps 200, monitor suddenly went black the other day in the middle of use. Noticed the power light had gone from green to amber. When I push button on monitor says it is in power save mode, to move...

Try connecting the monitor to a friend's computer. If you get some sort of a display it's not the problem. When you say that the computer makes a new noise like the fans are spinning fast, you might have an issue with the video card , motherboard, or power supply.

No sign of life from the display half but the bottom reads life.


If you have already checked the connections from the screen to the PC, check that you have a power light on the screen. (Green or Amber). If no light, check power to screen. If it is amber, then the screen is not getting a signal from the PC - recheck connections. I would suggest you try and connect the pc to a different monitor to check whether it is the screen or the PC.

If it is the same on another Monitor or if the power button is green on the screen, then the pc is not sending information properly. Turn the pc off manually by holding the power button on the bottom half for about 10 seconds. All lights should go off from it. Now turn it back on again and see what happens.

If you see loading windows and then goes black, do the following:

Turn off the pc (bottom half). Turn back on and as soon as you pressed the button to turn on, start tapping the F8 key until you come to "Windows Advanced options" screen. use the arrow keys and go to Enable VGA mode. Press the return key twice. If it loads to windows, then fine. If not, then you may have a problem with the display adapter.

Hope that helps

Your Monitor is not connected properly

Connecting Your Monitor
1. Turn off your computer and unplug the power cord.
2. Connect the white connector end of the DVI cable attached on the monitor to the connectors on the computer.
3. Connect the USB cable that was included with your monitor to the computer and the upstream USB connector on the monitor. Once this cable is connected to the computer and the monitor, you can use the USB downstream on the monitor.
4. Connect any USB devices.
5. Connect the power cord.
6. Turn on your monitor and computer. If you do not see an image, see Troubleshooting Your Monitor.

NOTE: The Monitor will display full screen in White, Black, Red, Green and Blue color rolling pattern on screen if the DVI cable is not connected. This self test pattern will be displayed continually when Monitor detects that DVI cable from Monitor to PC is not connected.

* Check connection integrity at both ends of the video cable.
* Ensure the monitor and computer are plugged in to a working electrical outlet.
* Ensure power button is depressed fully.

PC or monitor, signal problems

your monitor is telling you it's on it's last legs..either that or your compaq has a bad video section. either is more vital than a video cable being loose.

Blank Screen

Can you see anything at on but dimly? If so thats is the backlight tube If you cannot see anything then it is a major fault eitherway a repair shop job I should think
