You could have a defective screen - a defective inverter or a CCFL lamp, follow this to determine the fault.

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.
  • 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 it up, 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.

Charging and monitor issues


If your AC Adapter and Power Cord is working fine, then your new battery has a problem if it will not charge. Just because it is new does not mean it will work.

As for your Monitor, try the steps below. Because it works with an external monitor, we know your Video Card is working fine, so the problem is either the LCD Inverter or the Lcd Screen itself is bad.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

Try to plugged in external monitor to your computer. If you did not experienced this problem using the external monitor then this is not a mainboard issue. This could be an LCD issue. You need to call the manufacturers tech support department and have your computer repaired. Same goes also if you experienced same problem using external monitor. You still need to call dell tech support department for mainboard replacement.

Display after rain went black


If your video output works fine when connected to an external monitor, then the issue is with the LCD display panel. I’m afraid the only way to fix this is to have the LCD panel replaced.
