HP Pavilion Dv6-6160se Display :: Random Laptop Screen Black Out / Turn Off

First of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
 
To the problem now : A few days ago my laptops screen started  out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen  had no lights, and if i use a flashlight on it there is nothing. like its turned off completely.

Before this happens. This behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a random color (green mostly) then becomes black/shuts down.

NOTE: The laptop keeps running, i can hear the videos playing so it probably isn't a gpu chip or gpu issue , music and games.
 
Here are everything i tried and all or the details i could accumulate in past couple of days:
 
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered (  on both amd and intel ).
 
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
 
3. I tried installing 4 different drivers all with clear install. ( didn't work)
 
4. I tried to  to recover system with restore point. ( didn't work)
 
5. I tried to lower the screen brightness. ( didn't work)
 
6. tried this trick: Turn off laptop.. Remove battery.. Hold the power button for 30-45 seconds.. Plug-in the charger ( don't put the battery in )Turn on laptop and see if it works. 

Very Noticable details:
 
7.  Since  on of the rare fixes requires to move the lid  i tried shaking the screen a bit or pushing it slightly to different directions. This actually  does the trick and turns the screen back on ( i am right now typing  this after using this "trick"
 
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure ...
 
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see  your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
  
Currently the screen looks ok ( maybe its the certain angle it has after i moved it. Tried to play a game for a few mins and i got the black screen again. Closed the lid  so the laptop goes in sleep mode then opened it and it worked. Just for the records.
 
Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers? 
 
Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed) ...
