Re: dell insprin 6400 panel problem

You may have a failing LCD or just a bad inverter.
If it does need a screen you can get them on ebay for $100-$180 depending on condition.

You would probably have to have this tested in a repair will have to be disassembled and tested with a known good LCD.

Get a recommendation from a friend that knows a place that does good work on laptops. You should not have to pay more than 1/2-3/4 hour for disassembly and diagnosis.

My dell inspiron 6400 has small horz line on screen

If you have tried this with an external monitor (and the line is not there)
then the problem is either the connection on your display cable or (more likely) a fault on your LCD panel. If it's still under warranty I would let Dell take care of it.
If you want to do it yourself, you need to get a replacement LCD panel, take the screen apart (the top half of the laptop) and switch out the LCD panel. Some small Phillips head screwdrivers are required, the screw heads on hinges etc. are tiny.
While this is not an overly difficult process, it may prove daunting to some people. Most computer repair shops like mine would charge $30-45 for labor on this plus the part, which according to ebay will run about $75. Make certain you get the correct size, as there was a 14.1" and a 15.5" model (They are not interchangeable). Screen size is measured diagonally across the actual screen and does not include the trim.

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.

Screen wont turn on , i have a inspiron 6400 .. I rang dell & my extra 3yr warranty ran out just 6 weeks ago & * They WONT HELP*

when you say screen will not turn on it means we do not have display right? now, try this. turn off laptop, press and hold D key then press power button, check if the LCD will display colors if yes then it might be your video card causes the problem which needs motherboard replacement. if no colors appear then LCD needs replacement.

DELL inspiron 6400 not switched on

This is a no boot issue. Youre saying that you can perfectly run the PSA diagnostics but doesnt load Windows rather it stays on black screen, meaning the boot loader of Windows failed to load. You need to reinstall windows on your computer

Dell inspiron 6400 screen is fading

Sounds like the backlight is going out. Youĺl need to replace the LCD screen. You can find them on ebay. Just make sure you purchase the correct one for your laptop. You will need to take out the screen to see who makes it and the number. Go to to find your manual, if you feel like you can do it yourself.

Good Luck!
