Question about Dell Inspiron E1705 (DNDWGA3) PC Notebook

Dell inspiron laptop screen colours inverted (negative)

I’ve got a Dell Inspiron 1545 and the colours on the screen are inverted! This happens in the bios and continues through to windows. Dell diagnostics seem to show the displays working OK but theres a few colours on the test colour strip that appear a bit darker. When it plugs into an external monitor its fine so I’m assuming the graphics card is OK. I’ve replaced the hard drive, reseated the RAM and installed windows 7 updated all the drivers and bios with still no avail. Also unplugged the monitor to motherboard connector and cleaned it.

Ive run out of things to testdo! Im a PC technician so please feel free to give a technical explanation ix
Thanks guys
Rory

    If it happens in Bios it has nothing to do with the OS. I am a little confused about the test strip showing darker colors, are they inverted, or no? I've never heard of a screen failing in this way, but theoreticaly the board that tells the LCD what color to put up could be damaged. This is the board on the back of the screen itself. A similar situation when a failed LCD puts up a single pixel line.

If the same issue occurs in the BIOS your soluton is to have your LCD screnn replace or have your LCD inverte cable checked/replaced ^_^ this has nothing to do with the BIOS vodeo card drivers do not function in the BIOS to be able to do such in the BIOS screen

Hi paramvirgull...

Hook your laptop to an external monitor and see if the screen comes on...if it does then your lcd screen is faulty and needs replacment.
If it does not come on then re-download your video driver/s. If that does not work.
Maybe your lcd inverter or backlight bulb is faulty and needs replacement.
Please take time to rate me thumbs up

Hi lewis haywar,

Try to replace the LCD inverter in your laptop. Most common issues on LCD are due to failing LCD inverter. It fails more often than LCD cable or LCD backlight does.

Please let me know if this solution helped to resolve your issue.

Are you sure the new screen was working before you fitted it? What was the fault with the original screen? Have you tried connecting an external monitor to see if the Laptop is otherwise working correctly?

My Inspiron 1545 turns off when I unplug it from adapter, and when plugged in, the power light on front flashes four times orange and one time white repeatedly.


Does the battery for dell inspiron 1545 plug in. It maybe because the battery pack is too hot ,you can turn off the laptop,let the pc notebook and the laptop battery both cooled down.Then try turn on it to see. If still happen to the matter,it must because the wrong turn off did harm to your Inspiron 1545 laptop adapter.

The LCD is definitely shattered, looks like pressure was applied from the back of the screen (Pressed on, laid on etc) and the LCD will need to be replaced.

The screen on my dell inspiron 1545 64 bit windows vista is darker on one side than the other and sometimes flickers and progressively gets darker, could it be a driver? or something that i can fix online...


The CCFL [cold cathode Fluorescent] bulb is dying. Manufacturers use these thin 'tube' style lights at the edges of your display for laptops and LCD monitors & TVs. Don't let it go too long or you will possibly destroy the inverter that provides the power to light the bulb.
