Hi everyone! Very good forum! I tell you what happens to me, I have a sub woofer yamaha yst-sw015. The problem from the beginning was that I turned on the LED and not No audio came out, not even the kicking speaker. I opened it and saw a burnt resistance, changed it and burned again. Look on the Internet and many said that if that resistance was burned or regulators (which were also changed having the same result) the problem was the power burned. Desolder it and turn on the equipment and the resistance does not heat. Now the problem is that in Argentina this stk model is not achieved, so is there any replacement? Can you put another power adapting it to the equipment? Thank you very much!
