Greetings, Question about normal computer audio - the unit of +2 columns. In a column (in one) after 5 minutes of operation became there is a rumble strong. Not in a column, to be exact in one channel. Untwisted a box, saw that one transistor was turned off from the heat sink. I fastened it, but the audio a box any more does not work. The supply spark does not burn. A question: I a backlog while assorted something or this transistor was responsible for a supply and could burn down and become the breakage reason? On a picture I outlined pads of this transistor an oval. There what that shading or me seems.
