有

回頭訊號??水/火線倒轉, XLR 2/3倒轉...可能性太多..
冇法嫁啦, 掹哂D線, HiFi最基本連接試起, 冇事一樣一樣加上去, 睇吓邊件野唔生性....

其實一裝左有線條天線就已經係咁

試吓換咗有線果個分線器 :a009:

原來影響左係部Onkyo AV amp, 其他前級後級都冇問題 :042:

試左部AV amp接地, 電流聲細左小小但都仲係好大聲 :042:

但係一甩左有線條天線就乜電流聲都冇晒 :051:

I've same problem before, its cause by ground looping.

I resolved this by adding an ground loop isolator made by "Jensen - US" connect between the RF cable out from wall socket and cable TV box. I ordered this from US by email. The elec. current sound immediatetly disappear.

Hopes this help.
