I have this acer laptop been using this for almost a year or two and its my first time to experienced this kind of problem, my laptop won't display anything on the screen but the power supply, the fan and hard drive works very well. I tried the thirty-one-two method which means to drained all the power in my laptop but it didn't worked and now I'm using the VGA port to connect my laptop on any monitor and yes it does worked well.. But the thing is I don't have any idea how to bring back or rather how to fix my laptop screen to its original function which is the screen should display everything like it used to be... I definitely need your help guys! :( thanks.
