I have a Compaq Presario CQ40-337TU laptop with a 250GB harddisk and 2GB of RAM. I have Windows 7 32 bit. My laptop's screen becomes very blurry or vague sometimes after starting. This vagueness prevails and then it goes off automatically. Sometimes when I restart the laptop after observing the blurry screen, the very first screen — "Press esc key to..." — becomes yellowish. Is it a hardware problem? Or a software problem? How can I fix this?
I would call that one a hardware issue. It could be anything from a loose flex that connects the LCD to the mainboard to a faulty component within the LCD itself. In any case, these aren't really issues you can fix yourself easily or without voiding your warranty. If I were you, my first step would be a call to Samsung's warranty section.
