Dear Chayro and Syntax,
Many thanks for your advice.
I did contact the dealer as well as the manufacturer. It seem they in difficulties to find out what is realy happen to the unit itself.
I onced sent it to the dealer, they hooked it to their hybrid Audio Research amp and found that things seem just fine. But when I brought it back home, the problem remain occurs. Then I brought the unit again to the dealer when we finally confirmed that there is a Highly fluctuated DC Offset. Not as high as in my home AC, but that might be caused of their using power conditioner in their system.
They suspecting a leakage in the output capacitors, but considering of its sensitifity to the AC fluctuation I suspect a more serious problem in the upstream side of the circuitry, could be in the power system.
The manufacturer strongly suggested me to manage it through the dealer. While I am away, I did text the dealer to check the progress of their observation but no reply. I am affraid they in trouble of finding the real caused of the problem.
Perhaps I need to find the way to manage and repair it by myself, but need in advance advices before start working on it.
