For modern TV's like that, also the magnetized inductor for the S-Correction can be noisy; is very audible for normal 15kHz TV's the bad ones. For HDTV's (~31kHz) is unlikely.
Don't disregard the SMPS since even if the majority operates far higher than 15kHz, the closed loop can make oscillations and audio noise (rare, but can occur), and waveforms can have a lot of subharmonics at some pulse width.
