Hello there,
If there is a good soul that had expirienced the same problem or knows where the problem might be i would be gratefull for the answer.
I own an Asus n550jv laptop (not a touch screen). (full hd screen)
The screen is randomly going black (sometimes when i enter chrome, sometimes when I do nothing, random events), I can change brightness during that blackout (it can be dark black or light black). If i press my fn+turn off screen button the screen turns off (so that means it wasn't turned off only blackened) and when i move the mouse as it should turn on again it does but only for a milisecond and then goes black again.
Sometimes turning off the laptop or going to sleep mode helps but not always (sometimes i need to shut him down and leave it that way for a few hours and then it works perfectly fine as before).
So as you can see, the problem doesn't appear every day, but I noticed it appears more often when the pc is on battery (not a rule, it went black today on a charger aswell) and sometimes when i move him (just moving him few inches to the left or the right)
I went to check the problem out at my registered asus service provider and they told me it was a software issue (since it wasn't going black while it was in their hands) which i don't believe because it has all the drivers installed (maybe I am wrong but i doubt that).
It was working perfectly fine for a month and now I am expiriencing this issue again on daily bases.
For any clue or advice you will make me smile again and save me a lot of nerves.
Thank you for even reading this and good day to you.
Cheers

I'm personally not thinking software at this point.
If this only occurs after the laptop has been running for a while and never at startup, I'd suspect heat as the underlying issue. You can monitor your temps with CoreTemp http://www.alcpu.com/CoreTemp/ or HWMonitor http://www.cpuid.com/softwares/hwmonitor.html to see if you are running hot. You want to ensure the vents on the bottom of the laptop are not blocked or restricted, the use of a cooling pad can help with airflow.
Something that may be occurring here (which probably wouldn't be discovered by service) which relates to heat is that solder joints and/or motherboard traces can lose connection when the motherboard (or solder joint) heats up and expands some - if you have a...

Something that may be occurring here (which probably wouldn't be discovered by service) which relates to heat is that solder joints and/or motherboard traces can lose connection when the motherboard (or solder joint) heats up and expands some - if you have a dedicated graphics card in your laptop, it is more common (simply due to the heat graphics cards generate)
Check your temps, see what is being reported there
