Default ta8200ah humming?

hi, i have some zenith 50" tvs which are brand new but have a quite loud humming sound coming from the speakers, its the same on all of them so i dont think its a fault, i have tried removing the amp from the tv and putting onto some veroboard but its still the same, i have tried grounding it and have even tried it on my regulated, smoothed bench power supply, has anyone had aa similar problem with these chips or any ideas? thanks joe
