Sanatate permanenta!Poate ajuta:am avut un NEI cu acelasi simptom(acu mult timp).Cineva a incercat repararea sursei si a montat C820-1 micro/100V invers,el e cu + la masa.Tens. din sursa au luat-o razna,la fel si recuperatele s-au marit mult.Am gasit TDA3653-BV ars.Dupa ce am rezolvat sursa am inlocuit integratul si a fost OK.
