patulong po,,,pioneer mini-component,model:XR-P670F.
pag-plug pa lng ay ON agad sya tapos STANDBY na after 5 secs...pero yung power LED ay laging naka Standby....yung system ic(LC75394) nya ay nainit kahit standby lng....normal ang power supply...mga supply voltage.

nakahiwalay yung supply sa power amp(2 pcs of LM3886).....syanga pala,may supply syang 6v papunta sa system,....yung 6v ay nagiging 2v n lng pag kinabit ko na yung line papuntang system(pag naka-isolate yung 6v line puntang system ay normal na 6v galing PSU).
