I have the same problem. When turning on the laptop screen goes to white, I can hear windows starting but cannot see anything. I connected it to an external monitor, which will only display once windows has loaded. I then took the whole laptop apart and discovered the LCD cable was frayed due to a faulty laptop hinge. I replaced the cable and it was the same, just white. The problem I think is with the motherboard and the intergrated video card. Upon taking the whole thing apart I noticed that where the video card plugs in is right where the heat sink is and the cooling fan which gets exceptional hot. I figure it has fried the board to the extend the monitor will not work where it is plugged in, but the external monitor will work but only when windows boots. So sad to say because of the the heat this laptop puts off and if you have it sitting on your lap or bed or anywhere else that it cannot cool properly it has over heated and you will have to get a new motherboard.
