    Laptop monitor - permanent vertical green line


    The monitor on my Dell Latitude D505 is currently displaying a vertical green line from the top to the bottom of the screen, about 1/3 of a screen width from the right hand side. This line fades in during the Dell splash screen and persists whether I boot into Linux or Windows. I'm assuming this is a hardware problem, but does anyone have any definitive advice on what may cause this?

    Thanks.

    My first thought would have been a driver problem, but as it's showing up in both Linux and Windows, then it's not that !

    It could be a few things. Has the laptop been dropped or bumped recently ? Could be that the graphics card has been bumped a little and showing verticle lines. Could also be a failing graphics card, could br dead pixels, could be the ribbon connector for the screen is damaged or could be the screen is faulty. Not really narrowed this down any, sorry Ish, just could be a few things that would cause this.

    Out of curiosity, if you connect it up to an external monitor, does the vertical line appear on the crt/tft monitor ??

    Thanks for the input.

    Yeah I was thinking it was probably a hardware fault with the screen/video card/connector. It hasn't been dropped or anything - no more bumping around than normal (I take it home from the office each day so it does get moved quite a bit).

    No lines on the external monitor, which would support that diagnosis, I think.

    Yes, I'm thinking that should be my first port of call. Certainly cheaper than beginning by replacing things! Now to find out how . . .

    Hi , What was the final solution to this vertical line issue. My Inspiron 9300 is exhibiting exact same symptoms.

    Thanks

    I still have Next Business Day support for it so I contacted Dell. They agreed that it was a hardware problem and sent out an engineer who replaced the screen and the ribbon cable.

    Glad you got it sorted out, Ish. Plus, at least you're getting you're moneys worth out the Support

    Cheers aitken. Yeah I've heard some bad stories about Dell's support but I had no problems with this at all.

    Dell support rocks. They always do their best to help out. However, sometimes I get frustrated when I have to talk to a tech support guy from India and have trouble understanding him.

    Well, glad things worked out for you.
