Black screen- laptop only works with external monitor

I have a Dell XPS M1210. My screen is completely black but is running. I can see the everything on an external monitor but not the computer screen. Usually when I go into the NVIDIA control panel I can select a laptop display. The only options I have now is the Matrox display software and HDTV. I'm not sure why I have the TV option. Anyone have any ideas on how to fix this?- Thanks!

The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

If your Dell has a S-video output it could connect to a TV or a video device, which allows for a TV option.

Dell xps laptop lcd screen black


Hi,

If you have an external monitor, try connecting the laptop to it, then toggle FN+F8 to project display from lalaptop to external monitor.

If the external monitor does not have a display aswell (totally blank) , then its a problem with the video card.

You can also run an LCD Bist test by turning off the system , then while the system is turned off press D + power , If you dont hear a beep but no display at all, then its an LCD problem.


Hope this helps

Thanks

The inverter or backlight on the display may have gone out. Connect an external VGA monitor to the laptop. If it works, then the display has a bad inverter or the backlight CCFL lamp went out.

My dell xps m1530 turns on but the screen stays black. Did my screen break?


Connect it to an external monitor with a VGA connection. If the external monitor comes on, yes your screen is broke.

Lcd can not display


You may need a new laptop screen or there could be just a loose connection. The backlight could also need replacing.

I would take it into a repair shop and see what they suggest. New screens and backlights can be found on ebay and most repair shops will offer discount if you supply the new parts

My Dell xps m1210 has a blank screen when I turn it on. The hard disk spins (and works fine -- I pulled it out and hooked it up to another system), the indicator lights go on, and trying to send the video...


You said you hooked up your hard drive to another system, so I'm going to assume everything displayed properly and all that. You might not necessarily have a dead motherboard. It could very well be that your display is shot, which is $200+ to replace.

One way that might help you tell if its a motherboard problem or not is when you turn on the laptop if the hard drive indicator doesn't blink the way it normally does when it starts up, then it's probably a motherboard problem.

Hope I was of some help
