I would check the whole circuiut for cold solder/loose connections,
check ESR of as many caps as possible, look for any more open resistors
or bad semiconductors, be especially wary of any solder joint that
appears to have overheated.
Replace the defective components and best of luck.
DO NOT connect your speakers until you are sure the unit is working
properly with no DC on the speaker connectors or you could fry your
speakers.
