I just want to add my computer to the list of victims. I have 4 vertical lines that have slowly crept along the right side of my screen towards the middle. They aren't so bad right now, but I know it will get worse. I love that you made a site for this problem! It is beautifully designed.
I would like to know what the main cause of these lines is, so I could maybe figure out a way to solve the problem on my own since I won't get HP's help. I've thought about taking the monitor apart and seeing if cleaning it out would help, but after taking it apart a few times already to get to the fan, it is becoming fragile.
