Hi board,
I have a used KN2000 that was working ok (apart from fan not working) until it lost speaker sound on the left - i opened it up after doing lots of research, unplugged and replugged connectors, but I fear I forgot to reconnect the one black cable to the mainboard. Now I have a specific question because all of sudden the sound went completely and i only hear a really loud buzz when i turn it on, it says "initialized", then the fan (which wasn't working before) now goes on, and it stays like that.
In the attached picture, I've used red arows to show what look like solder joints on the board pins. Now i'm not sure whether these were like this beforehand, but i don't think they were....and no others pins look like that on the board.
1) Could it happen that the loose cable "shorted" and melted those pins?
2) Would that be enough to cause the behavior described above?
Would really appreciate any help as i'd love to understand these things better.
Thanks so much, Acorn
