SONY KDL-42EX410

Recommended Posts

am primit la reparat acest tv :sony sasiu EX1,( LED) ,care porneste pentru o clipa (apare sigla sony) dupa care dispare apoi iar reapare si tot asa o tine incontinuu. am verificat sursa ,scoate 3.3v,12v si 24v. ledul de pe panou este verde tot timpul ,nu trece in stand-by nici din telecomanda nici de la tastatura. am dezactivat tastatura dar defectul persista. practic nu afiseaza nici o eroare ledul fiind tot timpul verde. va rog daca ma poate ajuta cineva cu un sfat (schema o am de pe elektrotanya). multumesc!

-condensatorii din sursa sint buni ? chiar daca tensiunile sint ok ar fi indicat sa schimbati ceva elcouri in sursa , -in momentul cind face ciclurile descrise nu se intimpla nimic cu tensiunile ?

S-ar putea sa trebuiasca sa-i schimbi dump-ul la EEPROM. Poate cumva s-a corupt...
