To test whether this is, indeed, the cause of your problem, carefully move your opened laptop screen backwards and forwards, taking care to note whether there is any change in the appearance of the display. If you find that your display does change when the screen is moved backwards and forwards, it may indicate that the signal cable is at fault.If the screen cable is at fault, you'll need to purchase an adequate replacement.
