I have an Acer Aspire 1800 series laptop. It had, for a few months, a\nvertical band about 3/4 inches wide in about the middle of the left half\nof the screen that was brighter that it should have been, and it faded\nand returned from time to time. Now, The entire left half is screwed up,\nbeing black with vertical lines, sometimes a rapidly changing array of\nvertical lines. The right half works fine, and an attached monitor works\nperfectly all around. Any idea what this is? Does it sound like it is\nthe LCD? Is there anything else it could be? I had the backlight\nreplaced about a year or so ago, , but it worked OK after that. Any help\nwill be appreciated. Thanks, Greg.
