No visibly display output

I went to bed and closed the lid on my MAP. The next morning I opened it up and there was no display output. It was completely black.

I connected it to an external display and there is an output l.

I shined a flashlight through the logo and I can faintly see the display.

I reset the NVRAM by pressing opt + cmd + p + r and that didn't work.( did this a couple times)

So I decided to forget about it and gave it to my mom to connect to a TV and use. After a week of two of using it connected to a TV it turned on. There was finally a display output! But then I put it in a suitcase and it was shaken around and there was no display again. I reset the NV RAM and it turned on! Then turned off after I put it to sleep..

I've tried to reset the NVRAM and that hasn't worked. I can see faintly see some of the display when I shine a flashlight through the logo and it gives output to a external monitor.

What in the world is wrong with this?
