Buna ziua.Am ac. tv sasiu china tub slim 21", la care am inlocuit 2 diode din punte-1n4007, l-am pornit dar face un zgomot ciudat in stand-by(ca un traf care nu este strans bine), iar in functionare se mai estompeaza. Am inlocuit in sursa tranz. v501-B764 cu A1013, zgomotul aproape a disparut in stand-by, iar cu liniile pornite zgomotul este acceptabil. Ma intereseaza o schema pt. el:-procesor TDA11156PS/N3/3-cadre LA78141 9t8(cred- nu se distinge f. bine)-memorie 24C08-traf linii BSC 25 NO608,-sursa cu tranz. C3807, B764, C4460.Ce scheme am eu pt sasie china nu sunt compatibile.multmesc.cu stima!
