Problema baleiaj vertical TV LG model CF-21K51KEX

Recommended Posts

Va rog sa ma ajutati cu urmatoarea problema la TV-ul din titlu: dupa circa o ora de functionare imaginea se restrange la o singura linie orizontala.

Uneori cu cateva socuri isi revine, dar de cele mai multe ori nu. Cel mai des isi revine cand aparatul este "rece" (nefolosit cateva ore).

Ma gandesc la o lipitura rece, "activata" de incalzirea aparatului.

Schema am descarcat-o, dar nu stiu unde sa ma uit mai exact dupa lipitura problematica, cateva indrumari mi-ar fi de folos, sa nu caut pe toata placa.

 

Va multumesc.

Pe placa este un integrat  montat pe radiator  LA 7848 , refaceti  lipiturile  integratului si pieselor de pe langa el prima data !!
