|When I turn on my Sony Laptop the display will turn on but will have horizontal lines and looks scambled (so I cant actually read anything on the screen) This used to happen 1 in every 20 boots but now is a lot more frequent - 2 in 3 boots. |
If I apply a fair bit of pressure to the back of the screen the it will come good but as soon as I let go it goes all scrambled again.
I am able to hook up the laptop to an external screen so I know the video card is alright. I suspect that it may be a loose wire between the screen and the motherboard.
I took my laptop to a family friend who is an electrician and he said that I would need a new motherboard. Im not sure if his diagnoses is correct as the screen does work fine now and again and I can use it on an external screen with no problems. I guess its possible the connection to the screen on the motherboard is damaged thus the suggestion for the new motherboard. He said it would cost 295 for a new motherboard and 50 for labour.
I would appreciate any suggestions or thoughts.
