Having problems with your Dell Inspiron 9400 Notebook ?

Replaced LCD screen and video doesn't work.

\015 I had to replace the LCD screen on my laptop. The backlight comes on and the screen lights up but the video is not working. What do I do?\015

Answers :

The video feed (the largest of the cables) may not be seated correctly in the slot on the motherboard. Check that cable to make sure it is correctly installed as well as the flat cable on the back of the screen itself, that connection is the most commonly mis-connected cable. For the simple fact that with the tape, it may feel like it is plugged in when in fact it is not, but simply jammed behind the connection. Recheck your connections carefully and you should be ok.
