my laptops screen goes black

[great7]

(Asus N550J) Hello, my laptop is fine but when i open a browser/ the D drive or when i adjust the lcd, the screen goes black. and sometimes when im watching movie and the screen goes black, i can still hear the audio and mouse is working so is the keyboard. so when the screen goes black while im using the browser or other things, i close the program by using the ALT+F4 then i use the FN+F1 for the sleep mode, when im back ON, the screen is good but when i open the same program again its goes black again.
it happens like 20 times while im using the laptop and then it stops. its really annoying please help and sorry for my bad ENGLISH.

Sounds like a faulty connection somewhere between the LCD display and the laptop. When the screen goes black, if you jiggle it backwards and forwards, does it come back on?
