Display Distortion on Retina Macbook Pro 2014: Is it always the LCD? I have a 15&quot; MBP Retina from mid' 2014. Out of the blue the bottom 2/3 of the display turned a dim grey. Randomly this part of the screen will ghost images, flash white, and return to translucent grey. I have ruled out a software issue by resetting PRAM, SMC, and booting it into Windows.
My question is this: What possible parts could be causing this?

(On a possibly related note... I noticed under About This Mac &gt; Serial Number: Unavailible)
Combined with the lack of a serial number I'm thinking hardware damage. Possibly liquid spill or drop damage. Any pictures of the logic board?
