  6. check u muna spkr sa iba tapos check u rin volume control pag ayaw pa rin sundan u ang linya ng spkr papunta sa IC..sana mkatulong kahit konti...
     
  7. Check mo per channel.. kung transistor power amp malamang per channel nyan is protected. if integrated siya papalitan mo ng buong IC. but before that. try to compare the left and right channel ng PCB mo. Probable to check is resistor rated 1 ohms, rectifier 1amp and voltage checking.. subukan mo po.. after that kung wala parin. upload me picture baka makatulong ako.
