Have you check the cable that goes from the screen at the motherboard? Usually this cable is not visible; it is hidden it one of the joints between screen and main body of the notebook.This cable is the most common problem in the cases that the notebook keeps on working although the screen is black. You can check it by opening slowly - slowly the screen all the way up and closing again slowly. If there is a cut at the cable your screen will get black at a specific slope.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, accept my solution.

Thanks and regards

This could be due to presence of static charges on the notebook or hardware malfunction of the video card or defective LCD display screen of the notebook. To resolve the issue, perform the following steps.
Step 1: Hard Reset
To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.
This will discharge the static charges from the notebook. Now check if the display works fine or not. Incase, if the issue persists, then the video card or LCD screen must have gone bad, and to isolate the same, please connect an external monitor to the notebook and check for the display on it. You can follow the steps below to connect an external monitor to the notebook.
1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

If your notebook is under HP warranty, then contact HP to get the notebook repaired for free of cost.

Screen comes up for about 10 seconds, then goes blank


Hello Robert,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Dell Inspiron 9400 display goes blank after a few minutes


If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.

If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st

When you are able to view a video clip on the external monitor, We can rule out the issue with the software. Probably you need to check the connections and also the external monitor settings in the display. The reload might have changed the old setup
