I've got a second-hand c3000 two weeks ago. The inside microdrive was replaced by a Sandisk Ultra II CF(2gb). So the warranty was void. When I got this device, its LCD had minor problems. It I opened the LCD and pushed it to the end (180 degrees to the keyboard), its backlight would cease. The backlight would come back if I pushed it toward the keyboard to a positon about 90 degrees. I thought it was not a problem. But recently, the situation became worse and worse. If I open the lcd screen, the backlight would come up as usual. However, the backlight would cease if the degree between lcd and keyboard was larger than 60 degrees. I suspected that something was wrong when the internal microdrive was replaced. I am no expert in this and have no clues at all. Hope someone could give me some suggestions.
