Ce masurati dvs se gaseste pe sursa mica....de Stdnby...intrebarea a fost daca sunt toate tensiunile bune inclusiv cele din sursa principala.Nu fortati plecarea prin alimentarea separata daca nu ati masurat totul!!! Imi aduc aminte ca la modelul asta apareau frecvent probleme la Q1204 si respectiv 1201 de tipSMD din seria BC8xxx ...cu verificarea/inlocuirea obligatorie a diodei 1205 de tipul 1SS....Acum trebuie sa vedeti si conditiile date de procesor precum pin comanda ON/oFF ==> oscilator...==> si protectLE: trebuia sa fie 5V dupa primul IC regulator...verificati si alimentarea din el
