marckyy Posted January 17, 2014 Report Posted January 17, 2014 Salutare, am un tv Panasonic TX21 AT2P, sasiu CP-521P, problema este urmatoarea:- Imagine ingustata pe orizontala si verticala (1cm), cand schimbi canalul isi revine apoi se ingusteaza iar.I-am schimbat electroliticii din baleiaj si sursa (inainte sa-i schimb functiona vreo 20 min. apoi intra in stand-by).Am masurat tensiuni...bune, banuiesc trafu de linii.Ce parere aveti ?Multumesc.

ZWhk Posted January 18, 2014 Report Posted January 18, 2014 (edited) la cf baleiaj nu se ingusteaza imaginea, apar dungi pe vertical si orizontal sunt de obicei in jurul valorii de 420-460Uf / 16- 25v capacitorii.1.vezi finalul de linii treaseul pe schema sa nu aiba ceva vizibil(de obicei se duce un rezitor sau un capacitor ce alimenteaza/filtreaza un anumit pin} dar mai mult ca sigur e finalul, dar atentie de obicei finalul nu se duce inaintea caderii capacitorilor mentionati mai sus !.2.zi-mi modelul finalului am cateva placi..
