Hi , my dell inspiron 6400 vista has no disply but external monitor it shows fine ?


Hello,

If the external monitor is fine then there might be the issue with the display panel cable ( cable which connects mainboard with display) or the display itself. Ypou will have to replace.

Thanks

Laptop to TV Connection


Check if you are sending the signal to the external monitor. On my laptop with Windows 7, I can right click on an open section of the desktop and choose Graphics Properties. In this window, I can choose to send the display to the laptop's internal monitor, the external monitor or both.
Pressing Crtl-Alt-F1 will force the video onto the external monitor on the fly (Crtl-Alt-F3 goes back to the laptop's screen).

When I have added a second monitor to a desktop, I needed to reboot and allow new hardware to be found before the related Screen Resolution (right click on the desktop again) let me find the second monitor and choose if this was a duplicate or extended screen.

I hope this helps.

MY DELL 1525 TURNS ON AND THE NORMAL BLUE SCREEN APPEARS. THEN ALL OF THE SUDDEN IT GOES BRIGHT GREEN, THEN BRIGHT YELLOW, AND STAYS BRIGHT YELLOW


Hello,
Please connect your laptop to an external monitor and see if the output is the same. If it displays fine on the monitor, then we are looking at either a screen cable problem or a screen problem. If the display is the same as on the laptop, then it is a problem with the display adapter on the mother board.

All the best.

The screen is not coming on at all. i connected


With the external monitor connected, try holding down the FN key and pressing one of the F keys at the top of the keyboard that has a Monitor icon on it. This should turn off the external screen and show the laptop screen. If you press it a 2nd time, BOTH screens should show up. If still blank, Press again until the External Monitor comes back on. Then go to www.dell.com/support and go to Drivers for your Model. Then download and re install the VIDEO or DISPLAY Drivers. This should fix it if its a missing driver. If STILL no display on the laptop, call Dell.

Monitor does not work, computer starts up, dell prompts load, windows prompts load then screen goes black. i can hear everything loading but no display.


connect an external monitor on your machine and check if display is ok on the external monitor. if yes, try to re-install your video driver and check if display is ok on your laptop.

if both doesnt have display (external monitor and laptop's display) i suspected your lcd display is faulty.

Dell inspiron 6400 display goes off < 1 min after switch on time


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.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

The buzzing sound is most likely the inverter problem.

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.
Check out www.lcdparts.net for parts, repair service and DIY info.

DELL inspiron 6400 laptop screen turned black


this sounds like a classic case of inverter problems, it could be just inverter coil thats gone which is an inexpensive repair, if it is the inverter then its a bit more.
try the Fn the F key that shows two tv screen icons, it may just have switched to external mode by accident

good luck

Laptop goes dark


You can refer to this document for display assembly. It looks like the display is going bad. By checking the seating of the display cable, you're isolating the fact that the cable is connected.
