Neither are we. Make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple. If you did not purchase it from Apple then you will need to look to the vendor for service or How to find your nearest Apple Authorized Service Provider (AASP) or Distributor (AAD).
I should probably mention that the left side of my laptop got some water on it while the lid was closed (mostly got on charging/usb port). I dried it out in front of fans and a dehumidifier, but this problem arose 12 hours after the water was spilt. There is no other damage to the device other than the discoloration on the screen (obviously it's from the water). I just want to know if it is an inexpensive or easy fix (especially since the problem goes away sometimes on its own and then returns).
It has been water damaged. It will probably cost a lot to repair, but I can't really give you any cost estimate. You can take it in for a diagnosis and cost estimate so you can decide to repair it skip it.
