My neighbor has a lenovo g500 laptop. I have worked on this PC a few times in the past with software issues and back then you had to have the screen at a certain spot to keep the picture on. I started taking it apart and noticed both hinges are broke for starters. Now the laptop has to be over 3/4 closed to get the proper picture. At certain spots you get a picture but it is really faint (like there is no backlighting). Other spots you have no picture. I have 2 questions.
1. What senses whether the screen is up or down?
2. Do you think replacing the LCD cable will fix the problem?
