Last week my beloved Dell Inspiron 8600 displayed this lovely magenta vertical line down the side of the screen. I just chalked this up to the LCD failing and started thinking about getting a new laptop since I bought this back in December 2004. I lived with the line for a week until last night a yellow line showed up and as a bonus it comes and goes...it's like its at rave.
Two busted lines caused me to start looking hard at a new laptop and actually researching the cause of this problem. Apparently, Dell had issues with a handful of laptop LCD screens doing this and they're offering to repair the LCDs at not cost, even to laptops with expired warranties. My only issue is that Dell states it'll replace screens for free for systems purchased within the last three years...guess what? I've had mine for 3.5 years. I'll still try to get it replaced for free.
