Tv Panasonic Defect

Recommended Posts

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.

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..
