How can I stop the 15625 kHz line deflection frequency from infecting my entire Hi-Fi system whenever any video equipment including my TV, video sender, video recorder or digital STB is switched on, other than switching the whole lot off or disconnecting it from my amp or anything connoted to it connected to my amp. Even when the video input is not selected there is still a residual -60dB deflection tone present on all the audio outputs of my AV amp, whereas if I switch the video equipment off the audio is clean.

Would having a Hi-Fi system with isolated Balanced Line Inputs and Outputs prevent my audio being interfered with and why don't AV amplifier manufactures start making them?

Use the Optical out from your digital STB.

Yes, I've done that, but since my video recorder and other stuff also needs to be connected to the amp and that is also connected to the TV the 15625 kHz line deflection tone is still infecting my system on every audio input.
