I think that the sound problem was caused by part of the speaker contacting the frame. I put some electrical tape on it, and the sounds work fine now, so that was just a false alarm.
But I agree, I think my only option now is to bring it to a repair person, since I still haven't been able to find any messed up wires. I've heard that thermal paste can be used to mitigate the heat that these motor driver boards generate, but I don't know how effective that will be in my case.
