Why is the right side of my MacBook Pro screen distorted?

Question

I've had my MacBook Pro for 4.5 years and have really had little trouble with it. A little over a year ago, however, someone in my family dropped something on the laptop when it was closed and broke the screen.  One trip to the Genius Bar later and we now had a new screen, one that has again given us little to no trouble whatsoever since then.
However, as of a week or so ago the right side of the screen has become distorted.  At first, it was a minor annoyance, as it’s only about an inch wide and would come and go at random.  Plus, if I applied some pressure to the screen where the distortion appeared, it would go away.  Unfortunately, it would inevitably re-appear a short while later, usually if I lightly bumped the laptop or moved it a bit. 
Now it’s there all the time.  I’ll open the laptop to use it and, after a minute or so, it’ll appear.  Now the only way to make it go away is if I close the laptop.  I can still use the computer, but the distorted column makes it hard to concentrate, plus I don’t know if it’s wrecking the screen any further.  It’s hard to use various programs such as iMovie, as I’ll have to move them around so the distorted area isn’t covering any of my work. 
What could have caused this?  I installed any and all updates the other day, so everything’s up to date on there.  I always keep it out of harm’s way, especially ever since our incident last year.  When it’s not being used, it’s always on a soft surface, always under a bed, couch or some other area where our two-year old and cats can’t get to it.  I also never keep it anywhere other than our family room or bedroom, where the room temperature is never too hot or cold.  Trust me, nothing else has fallen on it since the new screen was purchased last year.
Are there any possible remedies to this?  Or is it back to the Genius Bar again?  I’m reluctant to try and take it apart at all, but if that’s my only option and there’s an easy method that won’t harm the computer, I suppose I could give it a shot.  Or if there’s some video card setting I need to adjust I’m all for hearing about it.

Answer 1

It fixed it self when i picked up to use it this morning. Thanks for the tip I'll try that when all else fails.
If anyone else would like to tell me what they have done to fix this problem I would take any other advice as well.
Thanks, Ashka!
