I have a Samsung R530 that my son broke the screen on. I replaced it, put it back togoteher and found the screen colors were washed out. I took it apart and found that I pinched the wires by the hinge while wiggling the wires with the laptop on. So I tried to pull them away from the hinge and the screen went totally off. I assumed that I broke a wire so ordered a new one. Put that in and no screen at all still. What else can I check to find out what is wrong?
