My guess would be that the display panel connector has come loose.  Check to make sure that it and the video card are still seated.

 

 

display connector is tight and the video card is still seated. Never took it out to begin with. Anything i can check?

found it. Little black screw that you have to turn to lock the heat sink down wasnt fully turned. Thanks

I'm glad that you found the problem and thanks for reporting back that you fixed it and what the solution was.

 

Have a great week.
