AW r4 washed out screen

So an Alienware tech came out and replaced my faulty motherboard along with GPU, the GPU now finally shows in the bios and system but there's a problem I hadn't had before that i do now. As you can see the screen is very washed. The tech told me that it could be the connector to the motherboard but since the connector worked with my previous motherboard then it could possibly be the motherboard again. At this point im exhausted with the amount of problems this laptop has had lately. Also to make sure it wasn't still the GPU I plugged my system to an external monitor and it didn't show the screen washing the laptop's screen does.

 

He buggered up the LVDS cable for the display when tearing your rig apart. you need them to replace the display now and also to bring out a mainboard just in case. I have done this and it was exactly like that.

 

It's possible it just isn't seated properly, if you can lift the keyboard and get at it you can reseat the cable on the MB anyways and see if that helps. Chances are the cable is buggered but it is worth a shot. Either way if you still have warranty phone and report it again, they will have to send another tech.

 

I presume that you still have warranty.
If you want, I can go ahead and check what's going on with this case.
Could you please go ahead and send me your Service Tag via PM?
