Having problems with your Dell Inspiron 9300 Notebook ?

Monitor Problems I have a Dell Inspiron 9300--the monitor is just black-you can faintly see the desktop--I can hook up to a projector and see everything clearly--when going between the projector and the laptop monitor you can see the desktop for about 15 seconds and then just goes black again-- I have replaced the internal battery and checked all my setting and have even restored my original settings but still get a black screen

Defective CCFL backlight may has the following symptom:
\015\012
    \015\012
  • Screen flashs on red/pink and off. \015\012
  • Picture stays on in red and slowly be come normal. \015\012
  • Picture flickering with dim display. \015\012
  • 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.
