Blue spots on ASUS portable LCD screen

Solved

Hello,

I bought a new ASUS A6JM laptop a year and a half ago. It runs on Windows Vista.

Here are the specs:

Intel Core Duo T2400
2GB of RAM
120GB
Nvidia GeForce 7600 (512MB)
15.4" 1280x800 pixels (WXGA)

My LCD screen shows blue spots around desktop icons, the mouse cursor, or even on all light areas (for example, a sun on a wallpaper with a landscape). These are not dead pixels since the spots vary depending on what is displayed on the screen.
It is not a graphics card issue either, as I have the latest drivers, and I have tested by connecting my laptop to other screens and the problem disappears.

I therefore suspect a loose connection... But what can I do, it's no longer under warranty? Can I do something to fix this issue or do I need to go to a repair shop? (If of course it is a loose connection)

(I did searches with man's best friend "Google" but found no similar problem, so it doesn't seem to be a defect specific to the series).

Thank you in advance.

Best regards, Benjamin

    Hello,

    I have the same problem and I wanted to know if you managed to remove the stains on your screen around the icons, etc.?

        Hello,
        I had the same problem with my Asus A6Km less than a month after purchase (with green pixels on black areas), the laptop went under warranty to Asus France and I picked it up a week later and it was working fine.
        I have a friend who bought his about two months after me, he had the same problem with red pixels that he sent back to Asus (but he had a different model).
        Today, my laptop is two years old and it's no longer covered by warranty, and it's doing the same thing again with indigo pixels on white areas, I mitigated it by lowering the display brightness to 96%; the problem is no longer visible but it hasn't been resolved.
        If you have any information to permanently fix this problem without going through Asus, I’m interested, and I'll keep you updated if I find anything.
        Best regards.

        I finally found the solution to my problem, and it's really simple! You can try the same thing I did; you need a Phillips screwdriver and 5 minutes of handling!

        On my PC, the problem came from the connector linking my LCD screen to the motherboard; the socket is rather fragile, and after transporting the PC, the connector slightly pulled out of the socket, causing the spots.
        To fix it, nothing could be simpler: on the back panel of your Asus (where the ventilation grille, the power supply, and most of the connectors are), in the middle, you'll see a small plate with 2 screws.

        See diagram:

        First of all, remove the battery and the power supply.

        No need to take everything apart; just remove this small plate (be careful, it's also secured with screws underneath) and you'll see 2 square connectors, one white and one black.

        Completely unplug them and reconnect both connectors by pressing them in properly.
        They need to be well pushed in straight; with fingers that aren't too thick, there won't be any problems! I used a small flat screwdriver to press down (being careful not to cut the fragile wires).

        Turn on the PC to check that the connection is correct; if so, the spots should be gone.
        If the spots are still there, try the manipulation once more.

        Then screw the small plate back on!

        You're done!
