I'm having the same problem and this is what I did.

Go into your picture settings on your tv and choose custom. Lower your backlight setting to 60-70 and the buzzing should be reduced significantly.

It's working for the moment, but I'm sure glad I got the extended warranty in case this turns into a real problem.
