So my sister and I were watching YouTube videos. She was holding a bottle of water and accidentally spilt a few drops on my rMBP's right speaker. Now the sound coming out of the right speaker is lower than usual (clearly lower than the left one). When it's not just me watching I usually connect my Pro to an external display. I regret not doing it this time. Now my question is, is it fixable? If I took it into a store will they be able to repair it?
