Buna ziua,

am un televizor Hitachi CX1626T diagonala 37cm 14" si prezinta un defect si anume: imagine neagra, cu o singura linie orizontala colorata.
Sunetul functioneaza perfect, schimbarea de canale este in regula, doar problema mentionata mai sus.

Ma poate ajuta cineva cu un sfat cu privire la reparatie?

Multumesc.

1. Refă lipiturile la transformatorul de linii.
2. Verifică existenţa tensiunii 24V ptr. BV. (Ce integrat are ptr. BV?)

Am refacut lipiturile.
Am masurat la integratul TDA8174A, pe pinii 1 si 6 si nu am tensiune.

Am atasat si schema electronica pentru sasiul Vestel 11AK36 A8.

Nu functioneaza, acelasi simptom.
