This problem is fixable with no parts.
the ribbon cable inside the back of the monitor most likely is loose. if when the screen goes black you can tell that the back light is still on inside the screen then this fix is definitely for you.if the back light is what is going off then you may try swapping the inverter from the other screen, this requires disassembling the screen to do, follow the instructions below to get it apart, then find the inverter at the bottom of the screen, but from what you said about moving the screen makes it come back on id pat its just the ribon cable as discribed below. the nx5000 has a notorious problem for the monitor going out, sometimes it flickers and sometimes it just doesn't show anything at all. the problem is often easily fixable in less then 20 minutes.
the cable that connects the computer to the monitor comes unplugged on the back of the monitor.
you will need to disassemble the monitor to do this fix, don't worry it is easy.
get a Phillips screw driver and a small flat screwdriver and use the flat to pry off the 5 round rubber plugs on the front of the monitor.
next use the Phillips to remove the 5 screws.
next use the Phillips to remove the 4 screws on the edge of the screen.
next using caution pry pull or rip the inside bezel off from around the screen, there is double sided tape holding it to the screen. careful not to break or disfigure the bezel durring removal.
once you get this off there is 4 screws into each hinge at the bottom of the screen. remove those.
now the outside cover will be completely lose and dangling by the wi-fi antenna cable.
now the connector on the back of the monitor is exposed and in many cases it looks like its is only half plugged in, plug it in all the way until it is even and turn the computer on, see if this fixes your problem.
you may put a piece of tape to help hold it in but i doubt it would really help.
reassemble in reverse order, be careful to route the wi-fi cables through the little opening or they will be pinched and your wi-fi will no longer work.
it may not happen again for years or ever, it is possible that some joker working at hp was lazy and left hundreds of these only half plugged in, or did it intentionally.

Good Luck

. if The screen flickers then turns dark,when you move it or tap it lightly on the sides, it may be due to Failed cable at the back of the screen or LCD
In some cases you might hear a buzzing noise coming from the area where the inverter board is located, it’s on the bottom part of the screen Troubleshooting: If the screen is black, look for the “lid closed” switch and try pushing it a few times. It’s usually a small switch near the hinges that is pressed when the lid(the screen) is closed. Sometimes these switches get stuck in the “lid closed” position that results in black screen(no backlight) or non-starting laptop. Also some laptops have a magnetic switch (newer Dells, most Macs, etc.) that doesn’t get stuck.
The most common failures are (in this order): inverter, “lid closed” switch, cable, LCD, backlight.
the display assembly.so open the display assembly check the cable fix it tightly and again if no improvement change the inverter PCB

I think the problem might be in your laptop screen,did you try to turn it on in different positions,I mean the part between keyboard and screen might be broken.I suggest you first reinstall windows/mac or whatever,then try in different positions(move you'r screen up down),and if nothing work,take it on service :/

Hook a spare monitor to the video output usually on the back, if picture okay! you may have a loose video cable, or intermittent LCD display. If spare is the same, it means the video graphic card is defective and is part of the motherboard.

Hi if you are getting nothing at all from the lcd screen (black screen with no cursor or icons) there are two possible causes 1st is the LCD itself it starting to worn out or sometime it is just the simple wire connecting the LCD to the mainboard to get the display that needs to be replaced.
If your getting a black screen with blinking cursor and you can still see the hp logo at startup you just need to update the video card driver of your laptop.
Have the HP check first the hardware side of your system so that they can replace the broken parts. thanks

Hi friend, In this case i would recommend you to please try and install the latest video drivers for the laptop and also try to move the screen of the laptop up and down to check if it makes any difference because it might be possible that the LCD cable is loose.

Inspiron 1521 green screen problem


Either the lcd cable is loose on the inverter board, the lcd cable is going bad, or the inverter is going bad. Usually this can be fixed by removing the power button bezel and making sure all the cables are seated properly on their connection. Removing the power button bezel varies from laptop to laptop, sometimes there are screws on the bottom of the laptop that you need to remove and sometimes there are not, it just snaps into place.

Thanks and please take a moment to rate as fixya.

A whole crapload of problems.


Not a hard drive issue I'm afraid. Sounds like they switched the whole system out. So you disassembled the laptop and put it back together? That's more than most of these guys can do. You've got a loose lcd cable, or memory is going bad, or there's a short in the case-palm rest area. All these are common with this model. Good luck

Laptop screen went out/bad


Hi falcon30, first thing I would suggest you do is plug the laptop into an external monitor to check that the graphics card/the laptop itself is functioning ok. All your need is a standard PC monitor with a VGA cable, plug the VGA cable into the blue port labeled 19 on the picture below. Turn on the laptop and if nothing appears on the screen, hold down the 'Fn' key and press f5. If nothing still shows than this suggests a different problem. If it shows ok on the screen however, and boots fine then it would suggest that something has failed screen-wise. This could possibly be fixed yourself if you feel confident enough, but without having access to the laptop I am unable to tell you which part of the screen has failed, so the whole screen part of your laptop would need to be replaced, spares for this sort of thing can be found on ebay, and disassembly instructions can be found at this link: http://h10025.www1.hp.com/ewfrf/wc/manualCategory?product=299255&cc=us&lc=en&dlc=en&product=299255&dlc=en&lang=en , you need to download the PC service manual. Otherwise you can continue to use the laptop with a normal PC monitor. If you need any more help just let me know, good luck and all the best. Si :)
