My ground looping problem was caused by my PS3's power cable being connected to an UK plug (the rest of the equipments (integrated amp, av amp, cd player, digital vcr...) were connected to US).Problem was resolved after changing to US.

但你部TV有經HDMI或者色差接駁AV嗎? 如有既話一樣有機會出現ground loop, 但ground loop多數發生係av bypass既case, 唔知你係咪。

我都係影音分家，好彩聽唔到 hum hum 聲。{:6_237:}
天線-->MTV3000(經濾波)->SAMSUNG LCD TV(經隔離牛)
Bluray(經濾波)->AV-AMP(美式)->Int. Amp(美式)

請問方法2好定3好?
我而家CABLE TV -> MAGIC TV -> TV
ONKYO 806 AV BYPASS CREEK INT AMP 都有呢個問題，一拔了CABLE TV 條天線就少左9成雜聲，睇戲要拔天線。
想問方法2 OR 3係咪都係做入CABLE TV果條就得? 如方法3，條水線駁去一個只用左L同N既電器既3腳插OK嗎? THANKS..

I have similar problem, once I bought my Magic TV 7000D, there is very obvious noise (hard disk nosise) not just humming sound when I swith on the Magic TV.Any idea how to resolve?

my connection Cable TV + Now --> Magic --> TV
                           Naim (av bypass) + Bluray play + CDP --> AMP

剛買了int amp就出這個問題了，好彩有你這篇分享，我把roksan K2 chassis gounding 同 onkyo 806的 chassis接在一起，hum聲也會減少

是呀, ground loop和器材係有好微妙的關係, 試多些唔同既方法效果也不一樣的。
