veirone Posted June 28, 2014 Share Posted June 28, 2014 am si eu aceiasi problema la un tv beko-21B9T44-TX sasiu 12.6, are sunet si etc doar ca nu are imagine.. mai apare si dispare se intuneca la loc. daca stie cineva de unde poate fi problema sa posteze. ms apropo condensatorii sunt oke decat ca nu am pe cativa condensatori tensiune si pe b+ la traf linii am 13v in stand-by si 11v cand ii dau drumul PS sunt mai incepator in electronica:) Link to comment
veirone Posted June 28, 2014 Share Posted June 28, 2014 oke, o sa ma apuc acum ca tot e placa data jos din tv sa vedem daca rezolva ceva. ms Link to comment
veirone Posted June 28, 2014 Share Posted June 28, 2014 refacut lipituriile trafo si tot asa sunt voltajele Link to comment
veirone Posted June 28, 2014 Share Posted June 28, 2014 (edited) am uitat sa mentionez, in sarcina cu sasiul montat in tv face un fel de bazait trafo linii si cand revine imaginea si cand nu este imagine, cand dispare imaginea nu mai este nici acel filament aprins.
