[QUOTE="mikelaubach, post: 7380503, member: 632557"] Something inside went "poof!!" I had an older amp that died, and having an electronics background (adn still having the proper tools), I tore into it to see how it ticked. I found that there was a bad solder joint that opened up. The amp did exactly as you describe - turned on, green LED lit, but no sound. Turns out the solder joint prevented the upper voltage to the rail, and the transistors cannot turn on because of that. Therefore, no sound. I did have to trace the lines and find the voltage, then find where it disappeared before i found the bad joint. It was NOT something I would have ever seen with the nekkid eye. Might be worthwhile to find a local electronics repair shop and see if they can fix it. [/QUOTE]
