My acer laptop went black

Few months ago my laptop fell from a very small height.But that did it.My screen went from bad to worse progressively.IT had whit stripes or it went all white and i had to hold it so it could be normal.by the time i took it for a consult the screen would go bad by every mive.he said that the screen cord is not out of place but he cant check if the cord is broken because he didnt have any good to check the laptop with.that happend yesterday.today i tried to turn it on but it wouldnt.i thought it was the battery but when plugged it wouldnt start either.i tried holding the power button down and the repushing it and the led light went on twice then dead again.Any suggestions as to what may be the problem?
