Question about Dell Inspiron 6400 Notebook

LCD screen partially display's

My LCD screen is only partially displayed. I have a black or sometimes blue or white area to my right side on the screen. When I press on the screen(Top just left of center-where the connector is), it sometimes resolves the issue and the full screen appears. Could this be the inverter board or the other board at the top of the screen where I press to get the full screen to appear. It appears at though the lcd screen is ok since it sometime shows a full screen. This happens at start-up. Usually when the full screen appears it remains for the time that I have the laptop on.

I also have a light blue streak just left of center that is about 1.5 inches. This never disappears.

    Thanks. That's what I thought. I did take the screen apart and reseated the cable to the board at the top of the screen, but was unsure about the inverter board connection. So I did not do the inverter board. I will try to reseat the inverter board.



    By the way. What is the board name at the top of the screen. The one with the warning about touching?

    I have the same computer (in the E1505 version) with an identical sounding problem. My screen is partially blank on the bottom 2/3rds of the display. Could this be the connection to the inverter board as well?

This kind of issue is usually due to a loose inverter cable, re-seating the cable is a relatively simple matter. 
If the laptop is still under warranty you should contact Dell to have it repaired, if on the other hand it is out of warranty you should shop around for a repair quote unless you are absolutely confident you can strip and reassemble your laptop.

    You seem confident so try re-seating the inverter board and, if you have one, give the connections a blow out with an air duster (available from any good hardware/plumbing supply/electronics store).

    As for the other board it's you're WiFi card and the wires are theĀ antenna.

Toshiba L675D, black spots


Your screen is shot or partially disconnected. A lot of laptops have the vid card to lcd connect in bracket that connects the screen to the keyboard. I have fixed many by siimply taking it apart and reconnecting the clip but the spots dont sound good. Ebay to buy one or Cl to dump it as a fixer. Either way its a waste of money to have someone fix it for you unless you do it yourself.

How to remove white and black leakage screen


Your lcd screen has gone bad and needs to be replaced. To isolate that it's the screen or the video card borrow a monitor from a relative, neighbor, friend or co-worker and plug it into the laptop. If the borrowed screen displays fine without any problems then your original screen is bad. If the borrowed screen shows the white area with black leakage ink as your old monitor then the video card in the computer is bad.

Plug in an external monitor and see if thedisplay shows up on it. It can be any kind of monitor even the old big fat crtmonitors as long as it has a vga cable to connect to your computer's vgaport. If so that proves your video card is ok. The video will showon most systems when you reboot without you having to do anything. Some systemswill require you to hit the FN (Function key) + F1 thru F12. Hold downthe FN key then hit the correct key for displaying on the monitor (F1 thruF12). The correct key will normally have CRT/LCD on it or it will havethe icon of a display.

This is likely the LCD panel itself - you are describing a left/right image error that can be only created by the left/right division by the LCD driver wrapped around the outside of the LCD panel.
If your monitor uses a separate circuit board to drive the LCD, it could be this driver board.
Either way, it will require an LCD panel - $$$

In LCD screens is a common problem that after setting a lower resolution than recommended you'll see a black stripe sometimes up and right, right click on any empty spot on your desktop and select properties then go to display options and move the resolution bar to a higher point and click apply also click yes in the warning display and accept.

An area on the display it's not working. PowerBook G4


I'm sorry to say that you will have to replace the screen soon. That vertical black and white lines that appear is the early warning signs that your screen will soon go blurry, or have a partial screen, or have it just stop working. This happens from the many times the screen was lifted open and closed and the ribbon cables just need to be replaced. And since the ribbon cables can't be simply unplugged and then replaced, you will just need to get a new replacement screen.
