Transformer Buzz on Panasonic TH42PHD5

My TV is about eight years old and the picture still looks great but there is a transformer on the power supply board that's starting to buzz loud enough that it's a little obnoxious. The loudness of the buzz changes as the picture changes. My question is, does this happen because of the transformer itself, or could it have something to do with another board or component and the load it's putting on the power supply? I checked most of the caps on the power supply PCB but didn't find any that were bad.
