P2412H, blank, power button on
Bought a P2412H monitor through the outlet about 2-3 weeks ago. The monitor now is blank, only the button light blinks blue. Holding down the power button does nothing. Is this something that can be fixed, or does it need to be returned? I tried to reset the monitor to no avail.
Please advise.

Thanks for your response.
Yes, the diagnostic and troubleshooting steps that you noted are also in the monitor's documentation. I followed all these steps to no avail.
I have a new Dell Laptop, purchased in late June. This monitor connects to the laptop, and for the first couple of weeks it was working fine. The problems started when I began to optimize the power management of my new laptop/monitor/external keyboard configuration. Last week I adjusted some of the power settings so that I could close my laptop display but still have the external keyboard and monitor working. It worked fine for the first day, but this first day the laptop didn't go into power saving mode. I then set the "floating dialog box" display option from "auto" to VGA only -- thinking that that will help the monitor know where the cable source will be coming from. NOW, the floating display no longer appears.
This is what the monitor now does:
- when all cables are unplugged from the monitor (usb, vga) and the monitor is unplugged, it does nothing (expected)
- when I plug in the power into an outlet, the blue power button blinks (about every 1.5 seconds).
- when I press the power button to turn the monitor on or off, nothing happens. (not expected)
- when I plug in the vga (or unplug the vga) I no longer get the floating dialog box. (not expected)
Basically I just get a black screen.
I just simply want to know what steps I need to do to either:
1) reset the monitor (the button 1-4 combination does no good)
2) Return the monitor for a replacement (I'm right near the 21 day return policy)

Hi jddalek,
Is it a Dell computer you are using with the monitor?
If it is a Dell computer, check the power light status on the computer. Please also check if the Caps lock, Num lock and Scroll lock keys respond or not.
Let's run a self-test on the monitor to determine the monitor's functionality. Please follow these steps to run the self-test:
You may also try to run the built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent problem with the monitor, or with the computer and video card.
NOTE: You can run the built-in diagnostics only when the video cable is unplugged and the monitor is in self-test mode
To run the built-in diagnostics:
The test is complete when the white screen appears. To exit, press Button 4 again. An image for the front panel buttons is shown below.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor is functioning properly. Check the video card and computer.
Please check if more than one cable is connected for the video signal. Please ensure that you are using either VGA or DVI.
You can refer to the user manual for this monitor for future reference

Do write back with the findings.
Glad to be of help.
