Daewoo model:K21C6NT Sasiu CP185....Tv pleaca din standby ledul se face verde si atat ..tensiunile din secundarul sursei sunt bune...singurele tensiuni care nu le am ..sunt cele de pe trafo linii..cea de 13,5v care alimenteaza B.V(tda8357). si cea de 45v...Sa fie oare memoria?...merge cu o memorie nescrisa?....sau trafolinii?

Dupa ce am schimbat T401...tv porneste dar la inceput 2-3 minute imaginea este multiplicata ..vede de 3 ori imaginea cu linii albe si se deformeaza geometric.iar in timp ce merge asa se aude un sunet in trafo linii . care dispare.dupa 2-3 minute de functionare isi revine treptat la normal si apoi merge bine......
