TV LG

Recommended Posts

Este un TV LG sasiu MC00AA trasnit.Avea puntea in scurt.Dupa scimbare TV porneste,iar dupa cateva secunde trece in st-by.Toate tensiunile sint OK.Am marit UG2,si fortind pornirea apare un rastru mat,cateva secunde.Ce parere aveti

Tensiuniile recuperate sint in ordine.Cum pornesc aparatul apar toate tensiunile porneste FIT,dupa cateva secunde scade 8 volti,si TV trece in st-by

Daca maresc UG2 apare un rastru mat,deci cadrele sint OK.Am decuplat alimentarea finalului video,doar se opreste TV.Eu suspectezi procesorul'fiind-ca se duce primul la trasnit,doar in rest merge totul bine.Am pus o memorie goala,doar face la fel.

Vinovat este memoria.Am fortat alimentarea de 8 volti,am marit UG2,si a aparut blue screen.La schimbarea canalelor aparea sus programul cu niste caractere ciudate in locul denumiri postului.Am pus o alta memorie,cu care la schimbarea programului,apare si rastrul cu pureci,nr.program,si alte caractere ciudate.Am pus alta memorie,alte caractere ciudate.A-si avea nevoie de o memorie inscrisa pentru sasiul MC00AA LG cu proc SDA5555-A007,fiindca eu nu am insciptor de memorii.M-ar interesa si un pret aproximativ.
