Every time i switch on the power, even without the video cable connected, the screen goes black after a very short time. If I'm quick I can press the menu button but it won't stay visible long enough to do a factory reset or anything else. If I switch off and switch on again, it goes back to the beginning. I also fiddled with the image settings just before this went wrong, as I was trying to set it up as an external display for a laptop. Is this a fixable problem, or should I give up? Has anyone else managed to navigate the menu buttons without being able to see the screen?

Re: Dell E171FP Monitor goes black after 2 secs
Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.

I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.
This generally is not good news, when the power comes back on it peaks causing the damage in it's wake. The power supply has been compromised and if you are very lucky you might get away with a fuse change. The monitor will need to be dis-assembled to assess the situation and hopefully it will start back up with minimal repairs. The fuse should be located near the power cord going into the circuit board.
sounds like either an LCD panel problem, or a video controller. First thing, connect an external monitor and test if the same thing happens with it. You may need to press FN + F8 together to switch the display to the external monitor. If same thing happens, there is a problem with the video card. Try to boot in safe mode and if same issue, you either need to proceed in getting a new video card/motherboard if the problem is happening even during the Dell BIOS screen. If it happens pass the BIOS screen only, you may try a reinstall or repair of Windows. If external monitor is okay, you'll need an LCD Panel repair/replacement. Let us know how it goes and your rating/comment would be appreciated.
Take a look at the back of the monitor there must be a cable which is connected at the back of your computer tower.
If you take a look at the back of your computer tower you will see that cable has a big plug with two screws on the top of it. It could be blue in color or may be grey. ( The name of that cable is Video cable )
Now what you have to do is to take that cable out of the computer. Now switch on the computer.
If you see a message on the screen saying " NO INPUT SIGNAL " :- That means your monitor is fine. If it does not shows that. Then your monitor is bad.
Remember the power cable of the monitor should be connected while doing the above steps.
Now incase you can see the "NO INPUT SIGNAL " message on the screen. Even then the problem persist.
It might be possible that the Video cable has gone bad. You need to consult a hardware technician for your monitor.
The screen goes black while in normal mode right? So try to boot in safe mode (power on then keep tapping F8 then select safe mode). Check if still happens in safe mode.
If screen does not goes black in safe mode it means there might be a software or driver causes problem when running in normal mode. You can try the following (update your anti virus software then run a full system scan, uninstall the video driver then download and install the latest one, uninstall any previous windows update or you can system restore to the time when it was working fine).
If the screen goes black even in safe mode they try connecting the laptop to an external monitor if still goes black, if yes then absolutely no issues with the LCD panel. You can try (uninstall and reinstall the video driver if still persist then this might end up replacing video card or motherboard, but before doing that update the BIOS first).
If does not goes black in ext monitor then the LCD panel might causes the problem. Reseat the LCD cable or inverter if you can.
-if you switch the computer on and it boots up and you hear the windows sound, this could be a possible video problem or motherboard problem -run the diags on the LCD, while the computer is off, press and hold "D" then press power button at the same time, if you see the colors red blue green without any problems then it is a motherboard or video card problem -another method to run the test is while the computer is off; preess and hold Fn then press power button, let the test run; when you see the question were colour bars displayed, press N, if you see the colors red blue and green without any problem then it is a motherboard problem or video card; otherwise it is an LCD problem -to toggle display on the external monitor press Fn then F8
Hi sglick - you will need to do a few simple trouble shooting steps to pinpoint the problem, as this can be cause by several different things.
Follow these steps and reply back with your findings:
1. Unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
2. Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
3. If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
4. Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots. With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting or sending a proper video signal to the monitor. Update the BIOS to resolve this issue.
If doing all of this doesn't change your issue of no video after seeing it pop on, try the monitor on a different computer/laptop, and if you have one, a different monitor on the system with the problem.
Let us know what you find following these steps and we can figure out what to do next.
I have the same problem its defenitly a problem with the lcd monitor not with the graphics card nor the pc. I hooked up the digital and afterwards the vga connection both had the same result. 1 s perfect screen all visible but than black. pushing the on/off or standby button again shortly 1s the display works than it blanks. Did the same test while connected to a dvd player via the composite video... same problem . Since the previous posts are that old and without a solution I guess there is no hope in getting it fixed.
