My second monitor of my dual monitor set up does not wake up:
The monitor seems to be in sleep mode and nothing will wake it up. The light (power LED) is in between an amber and green color (it does not flick, blink or anything, it just stays constantly on in the same color). And the monitor screen itself is off (ie no light flickering, backlight or anything) and it stays that way whatever I do: reboot my machine, push the power button, etc.
When I unplug the power cable from the monitor, the light stays on for a few seconds and then goes off. When I re-plug the monitor with the cable the same symptoms show again.
Is there a way to reset to a full OFF mode? And what do I need to fix/change to stop this happening?
This is a second-hand Dell E173FP that I purchased and set up as a second monitor in a dual monitor set up. It worked fine for 2 weeks. Then the problems described above started. At first, and for a few days, unplugging the power cable did work fine (ie. it put the monitor completely off and starting afresh after plugging it back) but now it seems just frozen in sleep.
My set up is the following:
- Dell Dimension 2400 with a Intel 845GV chip set and Integrated Video Controller (Intel 3D Extreme Graphics).
- Windows XP Home SP2.
- The integrated video controller is linked to my original monitor: Dell E172FP - which works all fine.
- The Video card for the additional monitor (the one faulty) is a 8MB Matrox Millenium G200 PCI graphics card (Model No: G2+/MSDP/8, bought second-hand as well).
- In terms of BIOS settings:
- I had to change the Primary Video Controller to "Onboard" instead of "Auto" for the Integrated card to be recognized as primary. Leaving it on Auto was putting the taskbar on the opposite screen to the desktop..
- The Power Management options are unchanged:
Suspend Mode: S3
AC Power Recovery: Off
Low Power Mode: Disabled
I tried several things such as switching connections between monitors and video controllers, plugging the integrated video controller to the faulty screen only (without the other screen) and rebooting my machine but that did not change a thing. It seems impossible to bring that monitor back to life.
It is really annoying as I had just thought of setting turning off the monitor to "Never" in the Power Scheme options in Windows Control Panel (and that seemed to have done the trick). But the problem occurred again when logging with a different user that used a different power scheme and now my screen is in that frozen sleep state which I need to get out.

It sounds like a dead display. Since you plugged it into a different computer we can rule out the computer itself. If the CABLE from the PC to the display is removable you might try swapping it out. If not, check for bent/broken pins on the connector.
If nothing looks wrong, then I'd say it's a safe bet the display has simply died and is stuck in standby mode...
Thanks for taking the time to look at and comment on my question.
It does not sound too good though... :-(
jamietoner:
The screen does not show anything at all so I cant access the OSD menu. I have contacted the previous owner (before your comment) but something tells me that I should not trust him, ie he pretends that he bought the monitor new and never had any problems or opened it up although after a closer inspection I can definitely see a bent in the little slot (as if somebody did open it or tried...). So the Dell guarantee idea might be out (shame as that was a good one).
jhance:
I have swapped cables and video cards to no effect. Connector seems all fine and even when the connector is not plugged the monitor does not behave as it should.
Basically I dont think the monitor is "dead" yet as this has happened last week but unplugging/plugging the power cable did get out of the standby/sleep mode (I might be over-optimistic here :-(. The basic problem is that the monitor not being plugged to anything else than the power cable is stuck in sleep mode and I just want to wake it up that last one time (as I now have set up my computer never to send my monitor in sleep mode). Is there a way i could open it and press a hidden "reset" button?
Suppose it *could* be something with inverter and/or backlight tubes causing overload of the power unit in the monitor. Difficult to pinpoint without measuring voltages etc inside, or by substitution of components by units known to be good. Definitely sounds like hardware and if you know someone whom you can ask to open it up and inspect its innars, by all means do so (for discolouring, loose connections and such).

Sounds like a bad monitor but here something to try. Reset factory defaults using the OSD menu (http://support.dell.com/s
