Hello to readers/members/veterans who knows how to help...

I bought this set of speakers since 2009. Ever since then I am very satisfied of the quality, although not much of functions, it gave a great deal of high powered volume for music and movies, especially personal use... (tried in living room watching movie and blast music, great!)

Now and then, whenever I turn on the power from the sub, usually, if I'm not mistaken, it came a "boom" sound, which naturally for me to understand most speakers have their own characters. But this time is different. It produced unwanted distortion sounds. Even so, I still persist to test it with music. Let's say I put Chris Brown "Run It" (booming bass kick test) and the sound crackling from the main LR, center and surround LR, not the sub. For some time, the distortion became lesser and still have some minor distortion going on from the background.

Later on, the distortion became sustaining, it never go less than usual . I've tested over and over again, only that I found out, when I switch to 2.1, the distortion went off and played the music or movie normally.

I've told one of my audio friend who's in professional audio field. He said it maybe the IC (I don't know what is that, can't Google the meaning, if you know please tell me) was faulty.

Little that I've my own experience of opening hardware, the console (some apply amp?) gave me a very hard time to open it, and it never been opened completely (the cover was like stuck at the front panel). How the hell to check any burned components in there?

Anyways, I use Digital Output (Optical SPDIF) for the audio connection from my laptop. I don't find my settings affected the speakers' distortion issues (tested).

Anyone who can troubleshoot this issue will be much appreciated.

there is a few not so smart people here who can't seem to locate a electronic repair shop......and yet can locate an professional audio field friend...
