First of all, I too, must thank you for your guys's patience. And excuse myself for taking so long to reply, but indeed these last days where impossible to me. But this HT thing was eating me inside the whole day while I was working, so I came home 1AM decided to take this to the bottom end.
okay, I was already quite in despair, so I start on doing all kinds of tests.. and FORTUNATELY in one unusual test I put the friggin' machine to work perfectly. I was actually, very reluctant to do that test because IT, could actually really blow the speakers, but since I was hopeless and already thinking they were blown, I tried.
Here it is : All the cables get divided in two on the edge, right? These two extremities on both sides will connect on the speaker and on the receiver jack. On each side, the division is one colored and one half-colored, half-black. For example: Each end of the blue cable ends has one part blue, and one part blue and black.
So, narturally I connected the blue part on the hole that had a blue jack in the speaker, and the blue-and-black part on the hole with a black jack of the speaker. And of, course, I did exactly the same on the receiver jacks, cuz I understand that you gotta stick the exactly same part of the cable on the speaker and the receiver, because of the polarity, and a switched cable could even blow the speaker, right???
So, I checked and re-checked all the connections and they were all 100% CORRECT, with the polarities completely right. At a stage of despair and complete bleakness I tried the absurd : I switched the sides of the cables of the red (front right) and green (central) and BINGO!!! Everything is working!!!!...
What would you understand by that?? A defect on the cables? Can this lead to a problem in near future?
