Permalink Thanks very much for your great Input... I have a Toshiba Satellite L755, and I had a white screen for the past few days and I was very angry since it has 2 years only so I did search on Google and I came to to this site hoping to get an advise and I read your input and I connect an external monitor and I did see the computer is working, and I did another search and I find a site selling computer's LEDs and they have video on how to change the screen and I did check it and I find the video cable is loos ... I used my glue gun to hold the cable and the computer back to work again .. thanks again for your input ...
