My HP Pavilion Screen Won't Turn On

My HP Pavilion screen stays black A black HP Pavilion screen can often be caused by a broken, (or inadequately attached,) screen cable, a faulty screen or a broken motherboard. Below, you'll find advice that will help guide you through your screen related problem. HP Pavilion screens that stay black/won't turn on  Explanations and solutions To establish the cause of your black HP Pavilion screen, attach an external monitor to your machine. Here, you'll find instructions on how to do this. If your laptop works when connected to an external monitor, your dark screen could be caused by a faulty signal cable, (the grey cable that is attached to the top, and back, of your laptop screen.) 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. At the bottom of this page, you'll find a handy list of screen cable suppliers. Remember: when trying to establish the cause of the problem, take care to note the circumstances in which your machine was damaged. For example, if your machine has been dropped or trodden on, the chances are the screen is at fault. If, on testing the laptop's keyboard and disc drive, further faults arise, the problem may be more severe.                                                                                                                                                         If moving your laptop screen backwards and forwards does nothing to change your black HP Pavilion screen, it may be that the screen cable is not sitting, properly, in its connector at the back of the screen. To check this, you'll need to have a look at the back of your laptop screen. In this free video tutorial, we guide you through the laptop screen removal process. Having removed the screen, you should see a ribbon-like cable, (the signal cable,) connected to the back of the screen, (running from the bottom to the top.) Check that this cable is being held in place firmly, both at the bottom and at the top of the screen. Once you have checked that the the signal cable is in place, secure the screen back in place and, see if the display will turn on.  If securing the signal cable doesn't fix your black HP Pavilion screen, the problem may be caused by a faulty screen. If this is, indeed, the case, you'll need to purchase an adequate replacement. Contrary to popular belief, however, laptop screen replacement requires very little technical expertise.
