There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Invertor board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both. But most likely it is the CCFL (Lamp). Its life is limited and depending upon how long it has been in use, you can have a better idea - if its the CCFL or Inverter.
Rest assure that your system is ok and you can check it by connecting you laptop with some external display, which would work fine.
So, my advice is that you get it properly checked by any professional for replacement of CCFL.

Hope this answers your question!

HI There,

You almost certaily are experiencing one of only 2 problems. Either your "screen inverter" or your "backlight" has failed. Since you have to expose both the screen and inverter to do the repair, it's always best to replace both the screen inverter and lcd panel at the same time.

Good job on hooking up to the external monitor. That ruled out a failed video card on the motherboard so count your blessings.

This problem is not Dell specific...it happens with all brands of laptops. It's a bit like your car. Things are just going to wear out.

Kind Regards,

Selk

Dell Inspiron 4100 flickering off and on Makes it extremily hard to work with . How can I tell whether it is the display or something else?


What happens when you hook it up to a external monitor? If it works fine with a external monitor, then your laptop monitor is going bad. If it does it with an external monitor, then its more than likely an issue with your laptops video adapter.

Dell Inspiron 1300 blank monitoe


Hello,

the problem might be from the screen or from the screen inverter.

Connect your laptop to an external monitor and try again.

If there is a display, then its obvious that the problem is from screen or screen inverter of your laptop.

Good luck.

Dell Inspiron 9400 laptop display problem


First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.

The screen is not coming on at all. i connected


With the external monitor connected, try holding down the FN key and pressing one of the F keys at the top of the keyboard that has a Monitor icon on it. This should turn off the external screen and show the laptop screen. If you press it a 2nd time, BOTH screens should show up. If still blank, Press again until the External Monitor comes back on. Then go to www.dell.com/support and go to Drivers for your Model. Then download and re install the VIDEO or DISPLAY Drivers. This should fix it if its a missing driver. If STILL no display on the laptop, call Dell.

Monitor goes blank


Try restarting the computer in Safe Mode and then check. In case it flickers in Safe Mode too, then the LCD screen might be damaged and you might need to replace it.

Boot problem on inspiron 1150


Try connecting it to an external monitor.
When you do, as soon as you press the power button to turn on the laptop, close the laptop lid - as this forces the laptop to display on an external monitor.
If this works, then it means the laptop screen is bad.
If it doesn't, the most likely cause would be that the laptop video card went bad.
For a while, some older Dell laptops with high-end nVidia graphics cards tended to die suddenly.
