Question about Dell Inspiron 6400 Notebook

1 Answer

The screen on our dell inspiron 6400 blacks out after being on for a while -- you can see a faint image on the screen but cannot lighten it enough to be useable. it also blacks out if the power supply cable comes loose -- even though the battery has a good charge. any suggestions?

This is typical of a back-light problem, especially when you view the LCD screen at a sharp angle and you see a dim Windows image. This fault is caused by either a faulty inverter or a faulty CCFL lamp.
The inverter supplies high voltage to the CCFL lamp. the CCFL lamp is a mini fluro lamp which fails with age and use.
This LCD screen can be repaired, the cost of an inverter and CCFL lamp.

Sounds like a bad drive but it may still have the data on it (hand it over to a professional).
Next time, don't forget to do your backups so you don't have to worry.

I have a dell inspiron 6400 and im getting a black screen once the dell logo comes up and windows xp loads...I see no icons or nothing..just a black screen


it sounds like your display backlight has gone bad. If your handy you can get a new display. If you are really good you can replace the back light.

Dell inspiron 6400 screen won't go 'full screen' on pinball (running XP Pro)


Hi Dominic
You need to buy a new computer, a Mac ideally.
A possible work-around for the 'not going full screen' problem would be to sit much closer to the screen, making the images appear larger.
If you could get hold of a magnifying glass from ebay this may help too.

The screen is blank but I can see a faint image.


Try reseating the cable that goes to the back of the lcd and also the other end of that cable that plugs into the motherboard. If that doesn't do it then either the lcd or the inverter is bad. Either way when you get a replacement screen for a dell laptop it normally comes with a new inverter as well. If your laptop is under warranty thru dell then you can get it replaced thru them. If you have your serial number then I can look it up and see if your system is still under warranty.

My Dell Inspiron 6400 is extremely dark. +brightness does nothing


Hi there.
Yes, if you can see a very faint image on the screen that indicates that the inverter or inverter coil has become defective and needs looking at or replacing.

Good luck and thanks for using Fixya!!

My Dell Inspiron 6400 screen is blank. I can see a very faint image of the desktop on the screen. What could be causing the problem and how do i resolve it?


It may have something to do with your adjustment of the LCD's brightness. Look for the brightness key in your keyboard and adjust it. Usually it goes with the Fn button.
